Reviews

Last Gen was better

"Last gen base 3.0 feel thicker and probably same amount of warmth. Just giving my real world experience using these daily. Purchased the 4.0 in end of 2024, thinking they would be warmer and ticker than last Gen 3.0. I was wrong. Waffle weave of what ever you call it, it is tiny compared to the 3.0. Maybe not important."

Joech (3/5)

Well made

"Purchased for tactical operations. Well made product with great heat retention. Used during cold weather operations and these extended the operational time of individuals, making relief operations an easier task. May be too warm in an active environment."

FNULNU (5/5)

The waist is too low and the inseam is to short

"You�re off to a good start with these. The material is great for keeping you warm but the waist needs to be about 4� higher so you can tuck a t-shirt I and stay tucked, to keep those cold drafts off your back and backside! Who likes �Plumber Butt�? For me, I need a couple more inches in the inseam. Make these changes and they would be perfect! Seems like an easy fix to me!"

UA Base 4.0 Leggings, Nice Warmth and Comfort

"Just used these leggings for the first time watching a football game in 36 degree weather and I was impressed with how warm they kept me. Wore them under a pair of jeans and made it through the entire game in comfort. Fit was snug but not binding, very comfortable. A little pricey but you get what you pay for and I�m glad I made the purchase."

Witz55 (5/5)

Very warm!

"I work outside at night with many nights reaching below freezing and this in conjunction with the matching shirt keeps me very warm. I highly recommend for anyone spending prolonged periods outside in freezing or near freezing temperatures."

BobbyJ0517 (5/5)

More than what I expected

"I bought this because I wanted some super warm clothes while being out in the cold for extended periods of time. I haven't tried with exercise yet. But, they don't seem so bulky that I couldn't."

Great product like all Under Armor

"Keeps very warm. Only wish is they need to bring back option to be able to use the bathroom without having to drop your pants. Kinda sucks having to do that when outdoors."
