The BaseCamp tracks true even in crusty, icy conditions, opening up more direct routes to your goals, allowing you to weave safely through the timber or link turns on mile runs down the backside. Made of High-Density Cross-linked Polyethylene (XLPE). Our harness is fully adjustable front and rear allowing you to keep the poles at your sides where they belong no matter your waist size. It's flexible, strong, comfortable and dependable. Your gear is carried in an 11,000 cubic inch duffel bag of 1,000 denier nylon. Two side release buckles and all your gear comes off the sled at once, together. Wide nylon straps make the whole sled backpack able for fording rivers, crossing pressure ridges, walking through airports.
