10 Reviews: Best Base Layers for Heavy Sweating (Apr 2024)

Designed specially as a training base layer to be worn under a mid-layer or jacket, you shouldn’t worry about sweat. Yes, it ensures your comfort with seamless construction and a flattering fit that isn’t too tight to wear on its own. Thanks to the merino mesh material, it will keep you warm if you wear it on a windy or cold day.

The polyester material makes this layer ideal for wearing on an active day because it is breathable and thus will keep you cool even if you sweat a lot. Even without a closure feature, it quickly dries your sweat. Not only that, but as you can see, it has a thumbhole to keep it in place so you can move freely.

Great fit! Super breathable material.

With the 4-way comfort stretch material, sure, it will make you do your workout more comfortable. Move your body freely without limitation, helping you to reach your goal. With the crew neck and long raglan sleeves design, let this base layer cover your skin completely.

Got a couple of these shirts for my dad who is a hunter. He will not go out without one!

This base layer is specifically designed for active women who sweat excessively while working out, and it comes in a variety of stunning color options to complement the outfits. It’s lightweight, one-of-a-kind knit, and soft against the skin, so you can imagine how comfortable it is. Oh, and it even has a watch window on both sleeves, so don’t hesitate to get it.

love the watch window and thumb holes. fabric is a nice lightweight fabric that even with longsleeves feels perfect with shorts or capris on those semi-warm days. ...

Smartwool’s lightweight merino jersey base layer is here. It does, however, have a nylon core, which makes it durable. Don’t worry, the Marino material is ultrasoft on your skin, so there will be no chafing even if you wear it for long periods of time.

Go to everyday shirt . By itself or as a layer. Also more breathable than a normal cotton tee. Quick drying and smell resistant . Dont let it snag on anything or you will get small holes.

Many people prefer base layers with thumbholes since they help keep the sleeves in place while still allowing for freedom of movement. One of them is this one. The premium material will wick away your sweat, allowing it to evaporate faster. It is labeled as a UPF 50+ base layer, making it ideal for workouts in the sun.

Love this top! I wear it mostly for sun protection on warm days, and it's light enough to be comfortable even when it's quite warm outside. Wore for a 5-mile hike this morning and worked great, and the pale pink color doesn't show sweat (a huge priority for me!). I'm 5'5", 120 lbs, 34AAA, and size small is great if a touch long (but didn't bother me). Will probably buy more, especially if they're on sale . . .

Helly Hansen, a well-known brand, offers this midweight layer to keep you warm in the winter or on windy days. Don’t worry, the fabric used can also wick sweat and trap body heat to keep you warm and dry. This base layer has odor-resistance properties to help you deal with the odor that often bothers your confidence.

If you’re looking for an ultralight base layer to wear while running or doing other workouts, this is a great option. This base layer is breathable, soft, and has anti-odor technology to keep you cool and comfortable. Because of the built-in sleeves, you can move freely while running.

Lightweight, super stretchy, slim fit, and is really breathable.

This baselayer will definitely protect your body by covering your hand’s thanks to the elastic thumbholes. It also has a flatlock seam and rib-knit collar with internal neck tape for chafe-free comfort, as well as raglan shoulder seams and offset side seams that lay smoothly beneath pack straps.

I bought these in a size medium for my boyfriend who is 5'10'' and weighs 170lbs. He loves how they are so lightweight and don't take up much room when hiking/packing in a pack. He also wears it ski touring often. Great base layer.

Finally, but not least. A merino wool base layer with thermal regulation and odor control to provide you with a comfortable layer to wear. As you can see, it has thumbholes for extra hand protection or to keep the sleeves in place.

this was very comfortable, keeps you warm and dry and not too sweaty throughout the day.
