Their return policy is excellent. I've seen some bozos return things like boots that they'd worn for a year, saying they didn't fit well or the soles were worn out.

REI took them back, no questions asked!
I returned a Giro helmet that was less than a year old. It was
red when I bought it, but after a year's worth of riding in the mid-day sun the color had faded. When I returned it the color was
orange.
REI gave me a new helmet.
