I've used this backpack hiking in Florida, as well as the Appalachian trail, Colorado rockies and in the smokies. Plenty of room for a multi day hike with proper packing! The waterproof cover included is great to keep your bag dry during those rainy days. plenty of small pockets and access points. Highly recommend!!!! I am 5'10 and on the skinny side but the adjustable straps make the pack fit just about anyone! Buy with confidence!
