Size XL: 220l bs, 5'10" male: fits really snug, leg grips still give sausage legs; I prefer my thigh position at a spot that leads to these grippers folding over a touch, but they grip appropriately and don't move once placed; chamois is super comfy, did well on a 60 miler without a problem, to that point that any distance beyond that would typically feel the same; straps are fabulous, no chaffing or movement issues; fabric stretch great for pee break; laundered up well with ease.
