These Hurley tapered pants are enough like trousers (and have the right trouser pockets) to wear when regular shoes and trousers are called for--anything short of the office or evening party. But they are sleek enough and slim enough to work for hiking or cycling when you don't want tights. Nylon so you get some sound of shushing but not bad. Very stretchy and easy to wear. They would work fine as yoga pants, and they don't have the casual look of sweatpants or tracksuit, so they are more versatile. Besides hiking and cycling in town for coffee, etc., I see these as useful for XC skiing, workouts in the gymn, chores or lazing around the house, camping, travel including especially airline flights... Best thing about them is they are thin and light but not gossamer or drapey. They fit easily over thin or thick tights if you need them to be a wind break over a thermal layer in the cold, but they are cool and comfortable by themselves for all day wear in warm temps.
Fit: the size L is listed as a 36-38 but it's closer to a 34-36 but roomy enough for a cyclist's athletic thighs and butt. The length in size L is a like a 30-32 trouser length.
