Base 4.0 Crew

When it's bitingly cold outside, layer up with the Under Armour Base 4.0 Crew. Made with thermal grid fleece, this low-bulk top provides huge warmth without weighing you down. Anti-odor technology fends off funky odors, and flatlocked seams provide a comfortable fit. The fitted design keeps it tight enough pull moisture away from your body, but loose enough that you don't get the uncomfortable squeeze of a compressive layer. Built-in thumbholes keep the sleeves from bunching when you layer over this top.

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.

Excellent quality and technology

(This review was collected as part of a promotion.) I bought the product to keep me warm while walking outside during severe winter weather, and it totally worked. I do not need to wear many layers of clothes to maintain my body temperature, I use the Women's UA Base 4.0 Leggings and the Women's UA Base 4.0 Crew underneath my pants and sweater and it is enough.
