1. its a fucking underarmour loose fit athletic shirt
2. it fits about the same as a regular tshirt
3. it isn't a tall tee, it isn't measured in height, it is measured just like every fucking shirt
if you want it to fit right, measure your chest
if you want it to fit loose, get a size up from a tshirt that fits you right.
i usually wear a medium or large tshirt, i ordered a large UA tee with the eye trip preorder, its a good loose fit for a wicking layer.
