Fit Guarantee

All of our Men's and Women's apparel and footwear comes with what we like to call a Fit Guarantee. If the apparel/footwear you purchased does not fit comfortably and you'd like to exchange it for another size, we will cover not only the cost of the return shipping, but also shipping the replacement size (if in-stock) to you. The Fit Guarantee only applies to shipping within the continental United States. At CampSaver you can buy with confidence that you will like what you buy, risk-free. Please allow 2 weeks for replacement item shipping. If you have any questions about our Fit Guarantee, give us a call at 1-877-883-6276.

Extended Return Policy

On top of our other fantastic policies described above, CampSaver has a very liberal 180 Day New/Unopened Return Policy. New, unused, or unopened products may be returned to us for up to 180 days, no questions asked. If you wish to return a new, unused, or unopened item after the 180 day return policy has expired, request a return or give us a call at 1-877-883-6276. CampSaver will accept those items at it's own discretion. If an item that is used is returned to us after the 180 day limit we will assess a 50% restocking fee.
