Customer Reviews Under Armour UA Base 4.0 Leggings

These leggings is something you definitely need if you are in a cold environment, especially in the winter. These leggings will definitely keep you warm. The sizing is spot on and it's very comfortable.

these leggings are very warm and comfortable . you wont be disappointed . you will never buy anything else once you have tried these . highly recommend this product.

This is my second pair of 4.0 also have the 2.0 cold gear i work outside all winter long in Boston and it gets fridged! But I literally wear these... carhart pants and a hoodie all winter with these bad boys underneath! 5++++++ in my book and i use them alot!

best base layer i bought so far, very comfortable, i'm 5,8'' 150 lbs and i wear 30 inch waist pants, the size small for me is just right. i wera these under softshell pants and even at -10C with wind im still warm.

I wear these under jeans and am very comfortable in temperatures below 20 degrees Farenheit. Another awesome product from Under Armour.

I first found that they may or may not have the right size but I felt these ones were perfect for my build i planned on using them for work and were able to keep up with my work regement. Keep in mind you have to keep moving to stay warm no thermals can prevent that.

My father, 96 years old just called to remind me to order his UnderArmor for the up coming winter. We all love them. All four generations of us.

These are the warmest long johns I have ever worn. Since wearing these, I have purchased another pair and have given away my other long johns. I also purchased the UA Base 4.0 shirt. The shirt is the warmest base layer. I will not purchase any other brand from now on.

I had an original pair of coldgear base layer from 2004ish and finally had to break down and buy some new ones. They've definitely come a long way in the past 14 years. They are much more comfortable, warmer, and i love that there is no longer a turtleneck. I would highly recommend them.

It keeps me very warm as I work outdoors at Lester B. Pearson international airport and when used with the matching thermal shirt I've been comfortably able to get through extended periods of time in -20 Celsius weather without the extra layers of clothing which makes moving in and around aircraft easier. I'm thinking of getting a second pair but waiting for them to go on sale again.

I purchased the 4.0 to be comfortable working outside. I am currently working close the the water's edge of Boston Harbor and it does the job of keeping me warm and comfortable. Been outside working in wind chill below 10F with no problem. Great investment. I'm glad I bought 2 sets.

Very warm and comfortable.

Used these as a base layer for hockey. Light and form fitting.

As a female with large calf muscles I've learned that men's leggings are usually cut a little larger in this area as I'm always having problems with this area, that's why I buy men's clothing at times. I found these leggings to be a little tight in that area. So if you are a guy with large calf muscles you are going to have a tight fit in that area.

Nice, would reccommned. I eventually will buy another

I bought this last year in case they changed sizing. I am 5'10", 165lbs. I bought the large and it is the tighest fitting clothing I have ever owned. You have to peel it on and off. Its fairly warm but too uncomfortable. A waste of money because I had to buy somethig else.

I purchased these for duck hunting. The day after I received them it was 18 deg. with a 25-30 mph. wind off lake Erie. Thinking they would be warmer than the Under Armour I had I wore the same clothes. I GOT VERY COLD !
