Amazingly light and quick to dry so the hoodie great for swimming or dancing. I bought a white that's great for reflecting light. Will be buying a black version for a more striking look.
I am 5ft 11in (height), 140 lb (weight), 30inch (waist), and got the large which allows a nice flow. I could go down to a medium for a more fitted look.
Shirt is very light and very comfortable. very breathable too...
wore it to go swimming and after swim i was still sweaty, but dries up quite well due to the shirt being thin and breathable.
I especially love the pockets on the shirt, can fit in quite a number of items in addition to my bigger than usual phone.
