But most other places don't offer return on climbing gear. Even REI said they wouldn't take back my approach shoes if I didn't like them.
Certainly no load-bearing climbing gear is ever returnable. Harnesses, ropes, draws, and pro aren't (and shouldn't be) returnable or resalable ever. I assume helmets can't be either.
But non-safety gear like chalk bags can be returned, and I'm surprised they won't take back approach shoes since they aren't even used on a wall.
