Good for Moderate movement

I use this product for work and purchased this product to replace my old Base3. I found the size to be slightly small/tight and the thickness to be good but the cold penetrated a little too quick compared to my old Base3.

3.0 Leggings

Geat product. Happy with my purchase. I would recommend

Great Base layer for the Canadian Cold

Feel like you are wearing a comfy "Batsuit" underneath your semi-formal clothes. The Base 3.0 is great if you live in southern Ontario, Canada during the wintertime. Ideal for wearing indoors in a drafty Canadian home. Suitable for wearing under dress or semi-formal clothing if you need to look professional and also go inside and out during the day.

This product lives up to its description

Awesome product lives up to description. Keeps you warm all day long. Thanks Under Armour.

Works as intended

I don't work in extreme conditions, usually it will get down to around 15-20 degrees at most during the coldest part of the season. These work well in blocking the coldness from my legs. The only issue is that Medium is slightly too small but large is too big, so I just need to make sure that I don't eat a lot while wearing these.


These fit perfectly, so comfortable and warm! I usually wear these in my sleeping bag and in and out of the tent during cool to cold late fall hunting.
