I am 6'2", 295 lbs., but my height is more in my torso than in my legs. I was disappointed that the XL Tall that I purchased fits me about like some competitors' Regular lines (think massive marketing campaign for a company that started in Minn.). Despite my size, the XL fit perfectly "around" my body. For those taller than I, though, this Tall crew may not be tall enough to remain tucked, undermining one important trait of any baselayer. The product is awesome, overall, re: material, warmth, etc. I just wish the Tall were longer.
