The Salamander Bak Yak Whitewater Kayak Backpack System is the ideal way to carry a kayak long distances. We use them all the time hiking into Vallecito Creek, Cascade Creek and any run that requires a hike to access. Equipped with ultra adjustable straps to fit a large range of kayaks. Thick 1/2 inch foam enclosed in the shoulder and hip straps make this backpack comfortable even with heavy loads. 1.5" wide adjustable torso strap running the length from the waist belt to the shoulder harness; truly "one size fits all" adjustability!
