VERY warm and comfortable
Color: Black-gray Green Size: X-Large
I find them very comfortable. When working as a paramedic, I sometimes have to be outdoors for an extended period. While others are shivering, I have been relatively comfortable.

Warm, comfortable, check sizing
Color: Black-gray Green Size: XX-Large
Bought these for my husband to use for snowboarding, they feel like they will be good for a base layer, and feel warm. He is an athletic build so I sized up for him which was good because the pants wouldn’t have fit in his regular size, but the shirt is loose now because of this. I’d say shirt runs true to size, pants run small. I ordered a 2x for him and he is 5’11 240lbs ... show more
