Nice Fit

  • Familiarity: I've used it several times
  • Fit: True to size

Got these for yoga class but can see wearing them backpacking or and kind of active sport. Very nice fit, clean classic styling I'm sure will last for years. PrAna makes great products.

these shorts are fantastic. lightweight, super stretchy and very comfortable. i plan on using these for pretty much everything! super comfortable, and the built-in compression shorts are nice so i don't always have to wear underwear if i don't want! 30 inch waist and i went with the S

These are my go to shorts for warm weather running and hiking. Built in liner is more simple and lighter than wearing separate boxers. Super stretchy and ultralight.

Ultralight and ultra stretchy

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Had these in full length pants, first. Sufficiently stoked to order the shorts.

Unlike the pants, these have a loose compression liner, which is not so tight as to hinder airflow, yet tight enough so if you get inverted you won't be exposing yourself. Fabric stretches without limitation. Only one outer right thigh half-cargo pocket w/ velcro closure. Probably could swim in these, but not surf. Medium riding low on the hips comes to mid knee cap on me (6 ft 170). Bought the large, but already returned it bc i'm not into the NBA look.
