The Osprey Kode 42 is a backpack with a comfortable back panel and adjustable straps. - Brand: Osprey - Model Name: Kode 42 - Size: M/L (18-22 inches) Thank you for viewing. I purchased this item around last spring, but I'm selling it because I no longer need it. It has been used very little and is in good condition. How about it for this season's backcountry adventures? If you are interested, please feel free to inquire.
