Super Lightweight and Comfortable!

I've used it several times
Size Bought:
5' 8"

I love every On Running Product I have purchased! These shorts delivered while I ran a 100 mile ultra marathon. No chaffing and the lightweight properties make it a comfortable and supported ride for short and long distances. The shorts are not too short and not too long which makes it for a great streamlined fit. Honestly the perfect short for me.
