There is only one way to make a bag truly waterproof – by welding its seams. For the Barrage Rolltop Chrome combined a Welded-Waterproof floating bucket with an abrasion resistant HD Ballistic Nylon outer shell to make the toughest waterproof rolltop possible. It features a low-profile design and side compression straps for load stabilisation and increased visibility, and a Welded-Waterproof bucket liner that can keep personal items bone dry in any weather. The Barrage adapts to accommodate a range of cargo. The main compartment expands from 22L to 34L. Each Barrage is made with military grade materials and specifications. The 100% Welded-Waterproof bucket liner is made with 600 denier truck tarpaulin. The abrasion resistant outer shell is made with HD Ballistic Nylon.
