Very light material. Better for hot summer day riding. silicone band on the legs are actually on the outside but it seems to work ok. Light color is almost see-through and leaves nothing to one's imagination. I'm a 5'8" 145 waist size 31. M fits well but seems like Small would be a good fit as well. low rise actually come in handy if you have to stop on the road for a quick excess water dump.
Just what i wanted. very light, folds into almost nothing. good quality material. small pocket on the left side near the waist come in handy, reflective strip across the back adds a nice touch of safety. I'm 5'8" 145lbs. Size small fits nice and slim.
