This fits me like a pair of Lee jeans. I've got large thighs and a smallish waist. And these fit perfectly with allowing movement. And there is no gap at the waist. I tried on 12 pairs of bicycle shorts with the over shorts, and these were the first pair that truly fit. Order a few sizes, I noticed the sizing was not consistent between the regular hummvee shorts and the 3/4 hummvee shorts.
