I ordered the REI Flash 52 Backpack for our recent trip to hike about 60 miles of the Appalachian Trail since mine was getting old and there were so many newer, lighter packs out there. I read a lot of reviews for different women's packs and decided to go ahead and order this one. Because there are no decent stores that carry hiking equipment in South Florida, I went ahead and ordered it from rei.com. I checked their measurement guide and found that I fell right in between the medium and large sizes. Since the large offered more cubic inches, I went ahead and ordered that one.
Other than the size I still loved everything else about the pack. On our drive back to Gainesville, FL we decided to stop at the REI in Atlanta. Can I just say that REI has an amazing return policy?! They took back my wet, muddy, used backpack and gave me a brand new one in size medium with no questions asked! One of the employees even took the time to load it up with some weight so I could walk around the store with it to make sure that the medium was the correct size. When I returned it the backpack was also on sale so they gave me a credit for that which I used to buy a new orange mesh camping chair. So now I have another new backpack, a mesh chair, and REI will continue to get my business!
