OK Lis, I have tried the "Hind Utility Bike Shorts" and here's what I think....

I have the same muscular legs so I got the medium size for extra leg room. This made them roomier in the waist but they have a belt and clip buckle system that does well, but I did shorten the belt on mine. It does have wide belt loops like baseball pants and is made of the same stretch material as the shorts so the belt doesn't dig in. The belt only goes around each side then the waist changes to a covered elastic panel. This is go for some flex and to prevent gaps. I would like to see this be a touch higher in the back but it's not low or anything.

The shorts are on the shorter side, with the 5 inch inseam but it's seems to be fine. The stretch material & crotch gusset are wonderful! The built in Mesh liner & seemless pad were cool & comfy. It looks like it has a fly but it doesn't and I really don't miss that. Lot of pockets, stretch, good looks, functional, a pretty good short.

I have the Hind Courier Capri that I like as well.
