Customer Reviews Under Armour Base 4.0 Crew

Works great keeps me warm during the cold days.

Keep me warm while doing ice rescue training

South Carolina experienced extreme cold weather this winter, but while wearing my 4.0 crewneck, the cold weather did not phase me not one bit. I see why the athletes opt for this gear during cold weather games.

Absolutely amazing - wore on single digit weather and only my hands and feet were cold

This gear is amazing!! Top of the line! Remember to buy it on sale as 100 bucks is a lot!! Top and Bottom would cost you 200 gold coins but on sale 40% its only 120 gold coins!

I bought these for my boyfriend who is an avid hunter and Lineman, he loves them! They keep him warm without getting sweaty!

I dont like wearing a coat in Wisconsin. I wanted a solution that provided warmth while still fitting my aesthetic. This base layer 4.0 has been perfect for me. Its fitted, not bulky and makes a huge difference in keeping my chest and arms warm with just a long sleeve on top of it. I recommend!

This base layer is a game changer for cold weather. It is incredibly warm without being bulky it fits perfectly and wicks moisture like a pro. Ideal for any winter activity highly recommend!

The fit was great and the warmth is what I have come to expect with UA cold gear

This shirt blew my expectations away. I wear this on patrol and it keeps me warm throughout the night. I usually wear size L but got a M and it is nice and snug.

I have multiple sets of these and use them for many activities. They breathe well, they keep you very warm but not sweaty unless you are very active and not in the cold

My husband loves these Snug but not too tight Thick for winter outdoor work

These are so cozy. Highly recommend

I ordered this for cold weather days. I am absolutely happy with the product. It is great for cold weather days- wind, snow, rain even. I live in Wisconsin so I need this for the frigid days.

Very warm, was golfing in mid 30 degree weather and stayed warm! Only downfall is the seam across the shoulders! Other than that great product worth the money.

These are my 4th set of 4.0 there amazing great for long hunts in the cold!

Expensive but we'll worth it for my line of work. Can't stand to wear bibbs and jacket, with this i don't need to wear that heavy gear anymore

This Under Armor cold gear is the best there is. I work construction and when its cold outside it keeps me warm. Recommend this for anyone that has to be in the cold!!! Great product!!!

I bought this for my son and it works perfect for him during the winter months.

This definitely helps with staying warm on the very cold waterfront.

Very comfortable base layer shirt. And its extremely warm. No need for bulky clothing with this under a coat or sweatshirt. Worth every penny!

Warm use them playing golf in the winter stay very warm

This is great gear. Working as a k9 Handler I wore this under my uniform top during night tracking training in the woods and was very comfortable and stayed warm during our scenarios. Dont think about it. Just add it to your cart and complete the order.

I spend alot of time working outside In the winter these are phenomenal during the cold snaps

This was warm and durable. It kept me warm in the Alaska cold winter. I wish it had the thumb holes like on the ladies thoughthese are awkward!
