BaseCamp XL Military WS Pulk System

The BaseCamp XL Military WS "War Sled" Pulk System has been used by the US military for 30 years. 

BaseCamp XL is 59" x 22" x 7.5" weighing 12 lb / 5.4 kg and providing 385 liters of capacity. It uses a fully removable 4.2 lb / 1.9 kg Rolltop bag, with the pole and harness system weighing 4.5 lb / 2.0 kg. The XL provides additional capacity for expedition loads and can also be configured for CASEVAC. Total system weight is 20.7 lb / 9.4 kg

History of Wilderness Engineering XLPE Hull Use

XLPE (Cross-Linked High-Density Polyethylene) is one of the most fielded sled materials in U.S. military history, with over 10,000 Wilderness Engineering systems deployed worldwide over more than 30 years. It was deliberately chosen over rigid materials like fiberglass, epoxy composites, standard HDPE, and standard polyethylene because of its rare combination of toughness, cold-weather strength, and controlled flexibility in extreme cold. The manufacturing process results in an ultra-durable plastic without weak points in critical corners and edges.

Military Performance 

Built to handle rough operational environments, it offers a proven track record of durability across demanding field conditions. When pulled behind a high-speed snowmobile, a fully loaded sled repeatedly slams into hidden rocks, frozen ruts, and rough terrain. Rather than using a stiff shell that can crack, split, or break apart under heavy impacts, XLPE flexes to absorb shock and snaps back into shape. To ensure steady handling, the material combines the natural slickness of polyethylene for easy sliding with an engineered surface texture that helps the sled dig into side hills resulting in unyielding dependability.

Built for U.S. Military

Wilderness Engineering systems are built for the realities of U.S. military use. Personnel may come from regions with little experience in snow or extreme cold, so the equipment must perform reliably across a wide range of skill levels and familiarity. Our systems are designed to withstand hard use, accidental misuse, hot-container storage, worldwide transport, and demanding field conditions. Built for military maintenance cycles, the system uses common hardware where possible and simple Wilderness Engineering replacement parts for easy unit-level service.
