The Best Thermal Shirts For Women
When temperatures drop, you either need to bulk up or layer up. But if you're an adrenaline junkie, doing a cold-weather hike in a cumbersome coat can be a drag. Here's where thermals can really help. Stretchy, comfortable, and — most importantly — warm, thermal base layers are designed to retain your natural body heat without restricting your movement at the same time. Whether you're skiing, camping, or just want a bit more security when out doing errands in the cold, we've rounded up a few of the best thermal shirts available for women.
What to Look For
We took comfort, durability, and cost into consideration when vetting the top contenders on our list to make sure you get the best base layer for your body and budget. So, if you’re looking for a tougher thermal top that’s made to last through more adventures, then you can’t go wrong with the all-natural wool fiber top by Meriwool. But if you’d prefer a softer, synthetic option that also won’t break the bank, then opt for the more affordable waffle shirt by Fruit of the Loom. Check out the rest of our top thermals below.
Meriwool Midweight Thermal Shirt
A lasting layer
Though synthetic fabrics offer a cheaper alternative to natural wool, you just can’t beat the performance of merino fibers. Made to last through the years, merino thermals like this midweight option by Meriwool offer superior protection for sports as well as everyday wear. But while the 100% wool design makes this base shirt super warm even in icy temperatures, it still lets the skin breathe for a comfortable fit every time.
Pros:
- Spend more time hiking and less time washing your base layers thanks to the durable design of this thermal, which can survive both the washer and dryer.
- Keeping warm doesn’t have to mean looking drab. That’s why this thermal top comes in a range of different patterns and colors.
Cons:
- If you have sensitive skin, the wool fabric may make this thermal slightly itchy.
Under Armour ColdGear Authentics Compression Mock
More moves, less sweat
If you’re a fitness junkie, then you know the craving doesn’t stop when colder temperatures set in. In fact, that’s why thermal workout shirts like this compression base by Under Armour are so popular in the fitness community. Made for movement, this knit thermal is as comfortable as it is warm. While the four-way stretch construction lets you move in every direction, the moisture-wicking fabric will keep you dry no matter how much you may be sweating.
Pros:
- Unlike other thermal shirts that can bunch up and roll up while you’re working out, this snug shirt will stay in place as you move.
- The smooth seams on this shirt prevent chafing even during the most daring of stretches.
Cons:
- After several washes, this shirt can start to pill, especially in the underarm area.
Fruit of the Loom Micro Waffle Thermal Shirt
Save on cost, not convenience
Workout gear can be expensive, and that’s especially true for cold-weather activewear. Thankfully, though, the folks over at Fruit of the Loom designed a thermal with your wallet in mind. Their micro-waffle base layer top is made of a soft, stretchy fabric that can keep you warm in chilly to moderately cold conditions. And because it’s machine-washable, caring for it is as easy as wearing it. Best of all, you can get all this for a fraction of the price of other comparable thermals.
Pros:
- Fabric isn’t the only thing that can make a thermal itchy, which is why this particular base layer has a tag-free neck label for ultimate comfort.
- While the shirt itself doesn’t feel too heavy, the cuffed wrists trap heat in to warm you up without wearing you down.
Cons:
- This thermal runs small, so you should order up if you are normally between two sizes.
Prettoday Thermal Henley Top
Stylish yet supportive
Thermal layers can be worn year-round, but if you’re not a fan of the athleisure look, then it can be hard to justify living in your base layers. We love this thermal henley top by Prettoday because it combines the best of both worlds. Crafted from a soft waffle fabric, this shirt functions as a warm base layer while still looking casual with its looser fit and button-front neckline. It’s even offered in a variety of neutral hues to fit with the rest of your aesthetic.
Pros:
- Though this top has a looser fit, you can tighten it up as you need simply by tying a knot at the bottom or tucking it into your favorite skinny jeans.
- The longer design of this thermal means it covers your butt for extra warmth while also providing perfect coverage over leggings.
Cons:
- The sleeves on this shirt are long enough for taller women, but they may feel a bit tight if you have bigger arms.
Icebreaker 175 Everyday Short Sleeve Thermal
Heat in all the right places
Not all bodies are created equal, so it’s fortunate that base layers aren’t either. If you have bigger arms, for example, then the tight-fitting sleeves on most long-sleeve thermals may not be for you. Instead, try a short-sleeve alternative like the 175 Everyday wool top by Icebreaker. Quick-drying, odor-resistant, and designed for layering, this lightweight thermal lets you move without trapping you in at the same time.
Pros:
- Made of 100% merino wool, this natural thermal shirt is built to last longer than other synthetic alternatives.
- No matter how many times you wash this base layer, it won’t lose its flattering fit.
Cons:
- Due to its premium quality, this top comes with a higher price tag.
Frequently Asked Questions
How often should I wash my thermal shirt?
Most base layers are designed to be worn for several days in a row thanks to their moisture-wicking and odor-resistant properties. And if you’re wearing your thermals mostly in cold weather, then your body will be sweating less anyways. That’s why we recommend tossing your shirt in the wash after three to five regular wears. Washing it more frequently may ruin the fabric over time.
Can I sleep in my base layer?
Absolutely. The snug fit of most thermal shirts helps keep your body heat in without feeling too stuffy. This makes thermal underwear a perfect alternative to heavy blankets, especially if you’re out camping.
