So Warm!

[This review was collected as part of a promotion.] I love this baselayer - it is so warm! This has been the coldest winter we’ve had in New England in 10 years, and this has really helped for outdoor activities. Whether it’s been ice skating, playing in the snow with the kids, or just shoveling, I’ve been warm and comfortable. I would say this fits TTS. Highly recommend!

Keeps Her Warm!

Got this for my daughter, she is a teacher. Her room is cold and then she has bus duty periodically. So the 4.0 is perfect for being somewhat sedentary. Surprisingly, actually keeps her warm! She is a chilly person normally, so cold temps are miserable for her. We've tried many products. The Under Armour is work the investment!

I Will Never Take It Off

I am always cold. This is the solution! Love it!

4.0 Review Ll

The 4.0 top and bottoms are warm as toast. Bring on Winter

Amazing Quality

These are the best long underwear going. I mind the cold but not when wearing these.

The Warmest

The fit is loose but not so lose that I would exchange for a smaller size. The shirt is warm but not too warm when inside. Outside it keeps me toasty at 30 degrees and I’m always complaining of being cold. All in all, I’m very happy with this purchase.

Excellent Baselayer: Under Armour Base 4.0 Crew

I recently purchased the Under Armour Base 4.0 Crew, and it's exceeded expectations. This top delivers comfort, warmth, and performance.

Awesome Product

Very comfortable, warm, and correctly advertised

Warm And Quality Baselayer Top!

Warm, thick, and Quality Baselayer Top. It just 2 inches longer than most brand. I hope that you can me the top and the bottom 2 iches shorter. Than It would fit me perfectly. Great product!

Great For Winter Sports

Very comfortable and warm.

Not The Same As The Original

Completely disappointed with the “new” version, was not warm at all. Will be returning. Please bring back the original!

Definitely Warm!

This is a great base layer and is comfortable under my ski jacket and pullover.

Very Warm For Cold Temps

I rely on under armour to keep me warm in cold weather conditions. The 4.0 is my #1 go to during the winter for outdoor activities. It is comfortable, easy to layer on top of it and just overall does what it needs to do.

Warm And True To Size

This is true to size, make sure you don't order too large.

She's Warm!

Gift to mom, she gets cold easily. And I swear by them, for work or play.
