Unless otherwise specified, all sizes in this post are listed in women’s.
1. A pair of fleece-lined leggings you can wear on their own on those pretty cold days to keep your legs toasty without adding too much bulk (and slowing you down). They're also great under snow pants when you go skiing or snowboarding!
Promising review: "These are the most comfortable tights I have run in. They’re perfect for the winter cold. I ran in these in the mountain winter at temperatures below 15 degrees, and they were perfect. In addition to buying myself another pair, I bought some for my daughter and sister because they were so comfortable, and they look great." —Amazon Customer
Get them from Amazon for $30+ (available in sizes XXS–XL and in 14 colors).
2. A cropped hoodie that has an adjustable bottom hem so you can either wear it cinched (and keep in your body heat) or relaxed (when you need to breathe). Plus, it's made of fleece from 100% recycled plastic bottles for a more sustainable addition to your workout clothes rotation.
Promising review: "I absolutely love this. I love the drawstring around the waist. You can create such a cute cropped look with this sweatshirt, and it’s so warm and soft!! It will stay cinched in all day, the drawstring cord is strong so you don’t have to tie a knot in it or readjust the string! Size up for a perfectly oversized look." —Megan D.
Get it from Girlfriend Collective for $92 (available in sizes XXS–6XL and in three colors).
3. A fleece thermal I'm pretty sure will become your new favorite base layer because the fabric not only wicks away moisture (aka your sweat) but also keeps you warm, no matter if you're going for a run or weight lifting in a gym with a sub-optimal temperature.
Promising review: "My lifting gym is primarily outdoors, so I needed some base layers to make the winter workouts more bearable. I'm very impressed with the quality, especially considering how inexpensive they are. Highly recommend!" —Elys
Get it from Amazon for $26.99 (available in sizes XS–3X and in eight colors).
4. A FP Movement pullover puffer with a really cool feature — it folds into a bag in its own pocket, creating a travel-sized pillow. That means you can take it with you on your trip and have lightweight yet warm top layer that will keep the cold out during that epic early-morning hike.
Promising review: "I live in Colorado at 7,300 ft above sea level. So I’m always looking for an easy warm puffer for the crisp fall and cold snowy winters. The design, fit, and function of this puffer is perfect for layering. I love the high hugging neck, deep pockets, and length. Super comfortable, light weight, and true to size. Perfect for all outdoor functions and adventures." —sew2soul
Get it from Free People for $198 (available in sizes XS–XL and in 13 colors).
5. A fleece ponytail hat designed with a drop down ear warmer for some extra protection from the cold cold wind. It also has a hole so you can keep your hair up and off your face because getting sweaty hair stuck to your neck is one of the most uncomfortable feelings in the world, IMHO.
Promising review: "I gave one to my sister as a gift, and she wore it for a week straight, even indoors. She raved about it, so I bought one for myself. It has made my winter running so much nicer by keeping my ears warm as part of an insulated baseball cap. I need the visor for bright days. I use the slat for my pony tail. It’s a snug fit, so if you require large sized hats, it may not be comfortable, even though it fits using an elastic rim. Can’t believe I waited this long to own one!" —HL
Get it from Amazon for $38 (available in four colors).
6. An insulated jacket reviewers can't believe actually works because it's so lightweight — until they try it out. It's got eco-insulation for warmth in wet weather, is water-repellent, and is moisture-wicking. You'll be ~running~ to grab it in the morning before you head out the door.
Reviewers do say it runs small, so order one size up for a better fit.
Promising review: "I wear this for running on chilly mornings in north Florida, good down to maybe 30–35 degrees. The fabric does feel thin, but my husband says it's similar to the latest materials worn by professional and collegiate athletes. It really is amazing how light but efficient it is. A small amount of insulation in the mid-section to keep internal organs warm. I may buy in another color. It's not too bulky." —Melissa
Get it from The North Face for $129 (available in sizes XS–XXL and in black and lavender).
7. A pair of thermal joggers, a must-have if your pup requires a daily walk, no matter the temperature outside. These pants have fleece on the inside and are water-resistant, so your legs won't freeze, even if it starts to snow when you're still a mile away from home.
Promising review: "I want these in every color. They check all my boxes and are not $100 like other similar pants. What do I like? They are super warm (walked my dog in 20-degree weather and my legs were cozy), high wasted so I am not always pulling them up, and an all-around 5-star jogger." —J. Raithel
Get them from Amazon for $33.99 (available in sizes XS-3X and in five colors).
8. A Ponyback beanie here to help you solve the dilemma of how to keep your whole head warm *and* keep your hair up during your workout. This hat is designed with a large magnetic opening down the back, meaning you can wear a ponytail with it one day and then with your hair down the next. You'll be ~a-head~ of the curve owning this genius beanie.
Ponyback is a woman-owned small business that was started by Stacey Keller, who was frustrated with the different hat options in the market, so she decided to create her own.
Promising review: "I absolutely LOVE my Ponyback beanie. It’s so nice to be able to keep my ears warm and wear my hair up without having to wear earmuffs or a headband. I’ve had so many compliments on it, too!!" —Bethany A
Get it from Ponyback for $30 (available in S–XL and in black and gray).
9. Or a moisture-wicking beanie if you don't need to have your hair up during your workout. This will keep your head from getting super sweaty but also keep it warm (so you don't lose any heat from your head).
Promising review: "I bought this to fit under my ski helmet to keep my head and ears warm, and it's just perfect for that purpose. It absorbs moisture well and is quite comfortable (as in not too loose or tight, and not itchy). Takes up no room in the ski bag or pocket, and would be a good cap to keep in your winter coat." —D. Bratman
Get it from Amazon for $13.95+ (available in 10 colors and also packs of two).
10. A cropped hoodie perfect to pair with your favorite high-waisted leggings because it will keep you covered without feeling bulky. It's a great layer to throw on as you make your way to the gym in the morning when you're too scared to look at the temperature for fear it will say, "Too cold, go back to bed."
Promising review: "I love this hoodie! It's so comfortable and perfect for the gym. I have a long torso, so I was worried the crop would be too short, but it’s the perfect length." —Amazon Customer
Get it from Amazon for $29.99 (available in sizes XS—XL and 26 colors).
11. Outdoor Voices FrostKnit leggings that have the perfect amount of compression — you'll feel more supported than when you tell your friend you're going for a jog, and they reply, "In this weather???" Plus, they're sweat-wicking, have a soft feel, *and* feature reflective details so you can be seen, even if it's dark out.
Promising review: "These are great winter running leggings. I like the bit of compression, but there's still a good amount of stretch. I live in Minnesota, and these have stood up to some pretty cold winter runs here. I sometimes have to wear a second layer on top, when temps really dip down, but these leggings are great either on their own or as a base layer. Love the color options and the reflective details. Also, I love a side pocket so I can keep my phone snug and safe while running." —Ashley
Get them from Outdoor Voices for $118 (available in sizes XS–XXXL and in five colors).
12. A three-pack of compression tops made with moisture-wicking fabric to keep you dry and comfortable during even the most intense workout.
Promising review: "Surprisingly, these shirts work very well. I expected them to be somewhat cheap and not fit correctly, but they fit well, not too tight, not too loose and keep you warm and dry. I exercise in Montana where it gets very cold, and when you sweat while being active, you are even colder. These shirts dry very quickly and give me good insulation from being too cold. They are thin, but they are supposed to be. Great as an undershirt for winter sports for sure and as an outer layer shirt to keep you warmer. I will buy some more." —Jyllian Stephenson
Get a three-pack from Amazon for $33.86 (available in sizes S–3X and 11 color combinations).
13. A vest providing you warmth exactly where you need it, but still giving you the ability to move your arms freely and without feeling like you're the Stay Puft marshmallow from Ghost Busters.
14. Windproof pants ready for whatever adventure you take them on — no matter if it's hiking, kayaking, or even just winter walks. They're made to be breathable, warm, and comfortable, plus they have plenty of pockets you can use to store your phone, keys, wallet, and (most importantly) snacks.
Promising review: "Bought this pair for my trip to Iceland, and they were great! I went to waterfalls, hiking, and they held up under rain. Super comfy and kept me warm in 50 degrees Fahrenheit and below temps because of the lining." —Alli J
Get them from Amazon for $35.19+ (available in sizes XS—XXL and 15 colors).
15. An earwarmer constructed from a combination of recycled polyester and elastane, so it won't be a ~stretch~ to say this will become your favorite accessory. It will make your ears feel like they're being wrapped in a warm hug, even if the wind is whistling around you.
Get it from Aerie for $11.97 (originally $19.95; available in red and blue).
16. A long-sleeve top that comes in many different options, including with or without a hood — you can pick the right layer that will keep you cozy yet covered.
Promising review: "This top is so comfortable to work out in, wear at home, or as casual wear outside the house!! I love love the feel and fit! I’m ordering another color!" —Nora S Marquez
Get it from Amazon for $25.99 (available in 1X–5X and in 36 styles and colors).
17. A zippered running jacket I'm convinced might be the unicorn of workout layers because it can do it all. Not only is it compressive enough to keep you warm during a cold morning run, but it also has mesh panels to prevent overheating, is sweat-wicking, has thumbholes, *AND* (maybe the coolest feature of them all) has built-in mittens!
Promising review: "This jacket has built-in mittens! Don't believe me, check my photo. Often when I go for a run I think, 'no, it's too warm for gloves.' Then a mile in my hands are ice, literal ice. I have two Under Armour tops with these kinds of built-in mittens, and I LOVE them. I would like this jacket even if it didn't have the awesome built-in mittens. Finally, a zip-up workout jacket that fits, without paying $90. Built-in mitts forever!" —NN Dye
Get it from Amazon for $20.99+ (available in sizes XS–3X and 28 colors, patterns, and styles).
18. Thermal workout leggings that come highly recommended by many, including reviewers who live in Minnesota, and they *know* cold there, so that's the highest stamp of approval. The moisture-wicking, brushed fabric is windproof, waterproof, and has reflective detailing on the sides.
Promising review: "Best light colder running pants ever! Just ran a 5K, 10K, and a half-marathon this weekend and ran in my Baleaf pants. They kept me warm. Not too hot. They were comfortable during all of my runs. I have two pairs and I might buy two more just to keep on the shelf for a later date." —Jillnaomi
Get them from Amazon for $23.09+ (available in sizes XS—XXL and in five colors).
19. A funnel neck half-zip hoodie you can throw on post Pilates class when you're still very sweaty but know stepping out into the freezing cold without a jacket just isn't an option. It's got a cozy relaxed fit, which means you might wear it on your rest days, too.
DYM Athletics is a woman-owned small business offering high-quality active and athleisure wear.
Promising review: "This is SUCH an amazing quality hoodie. The fabric is so soft and comfy to wear, it moves with you, and is so nice on a chilly morning or while you warm up at the gym. I will be buying more in other colors soon!" —Kelcee S.
Get it from DYM Athletics for $64 (available in sizes S–XL and in three colors).
20. A merino wool sports bra, which might seem like an odd choice for an undergarment while working out, but wool is actually better to wear than cotton in the winter because it wicks away sweat to keep your body at a reasonable temperature. Wool is also odor-resistant and super durable, which makes this a great first layer.
21. A compressive long-sleeve top meant to give you an extra layer during the colder months without instantly overheating you. Reviewers love the simple design and one of the coolest features — thumbholes to keep your hands warm!
Promising review: "I LOVE these shirts. I live in Wisconsin, and these tops with a running vest over them have been perfect for running in the winter. They pack extremely small and are great for travel. I frequently wear them on planes with a light jacket and leggings, as they are so comfortable. Really a great item for the price. I have multiple colors and wear each of them regularly, and they show no wear after weeks of regular use." —Beth
Get it from Amazon for $28 (available in sizes XS–XL and 23 colors).
22. A featherless jacket providing warmth without bulk, because it's made with recycled Thinsulate insulation. It also has an adjustable bungie in the hem to stop the cold air from finding its way to you.
Promising review: "Best jacket ever! I had this jacket last year and some how lost it at the end of the season. I was devastated! I walked in it all winter long! It kept me warm, and I love how it is longer in the back for extra coverage but still easy to move in! I was so excited to see it come back and snatched one up right away!! Great jacket!!!" —Deborah
Get it from Athleta for $129.99+ (available in sizes XXS–3X and in three colors).
23. Touchscreen gloves to keep your fingers warm *and* give you the ability to switch to the next song on your playlist without exposing your fingers. Plus, these gloves are thin, so you can use them as a liner during more intense winter sports, such as skiing and snowboarding where you need stronger protection.
Promising review: "I like these gloves because they are light and just warm enough for a run outside in the beginning of winter. I use them for playing soccer outside and the grip on them is a plus! I can also easily use my phone with them." —Amazon Customer
Get them from Amazon for $16.99 (available in unisex sizes S–L).
24. A pair of "CozeCore" joggers many reviewers love so much they have returned to grab a different color (or two). They're kind of a mix between a legging and a jogger with light compression and warmth that you'll be working out in all winter long (and probably into early spring, too).
25. A thermal half-zip fleece that may just be the Goldilocks of top layers because you won't be too hot or too cold while wearing it. It's meant to fit close to wick away moisture, has a deep front zip for ventilation, draft flaps to keep the cold out, and a zipper garage so that little bugger doesn't cause chafing.
Reviewers do say that it runs small, so size up for a more comfortable fit, especially if you want to wear another layer under it.
Promising review: "What a great top for cold weather! I wore this during my 50K trail race, and it was PERFECT. The temps were 25–30 degrees with 15 mph winds. This top kept me warm, it moisture wicked my sweat, and was super comfy. I usually wear a small but ordered a medium with the hopes of wearing a thin base layer underneath it when the temps get even cooler. It’s fit is snug, but I understand why, didn’t move around and kept me warm. I highly recommend. I’ll definitely be ordering more!" —Molly H
Get it from Amazon for $36.99 (available in sizes XS–3X and in nine colors).
26. A HeatTech-lined sweatshirt that may look like any old sweatshirt, but it's actually made with a special fabric that not only retains heat but also generates warmth.
27. Under Armour ColdGear compression leggings designed with a dual-layer fabric that has an warm, brushed interior and a smooth, fast-drying outer layer. Plus, reviewers confirm that these leggings stay in place, which means you won't have to waste any time pulling them up 1 mile into your run.
Promising review: "These are my absolute favorite pair of leggings. I cannot believe the quality for the price! They are the most comfortable pair of leggings I have ever owned! I run and work out regularly, and the first time I wore these, I ran 12 miles in the cold. They keep my legs warms and compressed, and unlike most pairs of leggings, I am not constantly pulling up the waistband (so annoying when you're trying to work out). They fit great and are not see-through. I absolutely love them, and they will be my go-to from now on!" —Kailey
Get them from Amazon for $49.99+ (available in sizes XS–L and in black and navy).
28. And a colorblock quarter-zip you'll be ~v~ happy to pull out because not only is it lightweight yet warm, but it's also super stylish.
