REI Pinnacle Hiking Alpine Backpack Model 13104 65 Liters 4 pounds 9 oz

I looked up the model number 13104 and found a review in Backpacker Magazine   The foam back panel slides vertically along two aluminum stays to fit torsos from 15 to 19 inches; it secures with large Velcro swatches that hold without a hint of slipping, eliminating the need to microad just throughout the trip. The large torso range makes it ideal for growing teens, the pack’s target audience, but one 50+ tester called it his favorite pack ever, proving that great designs have no age limit. Organization is big-load friendly: A large exterior pocket swallows extra layers, two pockets in the lid keep small items from sloshing around, and a full-length waterproof side-zip enables easy access.   Note: cover image is an AI approximation, please use photos of specific garment for reference.  Condition: gently used and in good condition. One of the zipper pulls may have been replaced (as pictured). I am not an expert on this, but all zippers work, and all of the plastic clasps work. There are two spots on the back pad, and a tiny wear spot (as pictured).   above description is based off of model number 13104
