I bought them for myself (female, 5ft 8in, 135lbs, size S). I wear them all the time. Free but not floating. The armholes are a bit deep so I wear it with a sports bra. Very comfortable, like the mesh of basketball shorts. Breathing. Work out. Airplane. Ideal for multi-shift use. I prefer hooded sleeveless tops. Also, it has a pocket! They are amazing.
