Osprey Kestrel 38 Size: M/L Color: Picholine Green Weight: 1.54kg The rain cover can be stored at the bottom of the backpack. The back length is adjustable from 19 to 23 inches (approximately 48 to 58 cm). I purchased this about 5 years ago from Wild-1 and used it about 10 times for mountain hut stays and river trekking, but I'm selling it because I don't use it often. I used it quite hard, so there are some minor scratches, but it's a very durable backpack, so I think it can still be used. Please refrain from purchasing if you are sensitive to used outdoor gear. I will lower the price at my own timing, so please purchase it when the price reaches your desired amount.
