The Crag Wagon backpack from Mountain Hardwear is designed with durability in mind. Combining a unique canvas material known as X-Ply™ Dimension-Polyant™ with a Kevlar® base, this backpack combines functionality with comfort and durability to create a great backpack for heavier gear setups in more extreme terrains.The Crag Wagon features a contoured aluminium frame combined with Hardwave sheet to distribute your load as evenly as possible to ensure a comfortable carry. This combined with adjustable dual-density shoulder straps and a removable, fully padded hip belt allows you to customise the fit and feel of your pack to suit you and the load being carried on that particular journey.The customisation continues, with the ability to either top load or panel load the pack. The front panel full U-Zip completely opens the pack and offers full access to to all contents of the main compartment with ease.

Additionally, there is an inclusion of a padded base to protect your gear and increase durability long-term.To further increase durability, Mountain Hardwear have treated the Crag Wagon with a UV resistant polyester resin to improve resistance to moisture and abrasion while the three-layer X-Ply™ fabric features a waterproof polyester film treatment for an extremely water-resistant construction.
