Patagonia is pretty good.
From their website: (https://www.patagonia.com/customer-service-faqs.html) We do not set a time limit on returns, though we ask that returns for fit or color be made in a timely manner and that items be kept in new condition with tags attached. We accept both current season and discounted items for return. Items purchased from a Patagonia retailer or authorized dealer that are new with tags attached can be returned with the Return Form and receipt for merchandise credit.
