Not bad, but I have a minor issue wth the shape in the front.  I am 5'7", 140 with 30"waist, slim/muscular.  Size small is a, good fit, but the way it's made in the front is awkward.  I would almost prefer it be more flat, then I could point up or to the, side, but the way this is made, the front seam leaves an odd protrusion of fabric right at the bottom off the pouch if I do so.  Pointing down is definitely how this is meant to be worn, but again the odd front seam pushes my head down and almost between my legs; this might be good if you like to look "tucked" lol. Not sure I will swim in this one, maybe just use as a workout brief.  Cool design though
