[This review was collected as part of a promotion.] Nice color pop with the orange stripe, admittedly that's why I bought this even though it was much more expensive than similar weight shirts (even on sale!)-- Lighter than other similar weight shirts, I think it seems warmer than 200 weight.
[This review was collected as part of a promotion.] It fit well and is warm. I gave it one less star because I bought it 2 weeks before the new color arrived. I wanted the other color. I purchased early because my discount benefit was about to expire.
[This review was collected as part of a promotion.] Is comfortable, though a tad itchy. Great body temp regulation and sweat dissipation. Doesn't smell after Sweating. Bought a size bigger assuming for shrinkage and weight/muscle change.
[This review was collected as part of a promotion.] Bought it for my husband. He had the green one and wears it constantly in the winter! Gives him another option.
