In celebration of our 70th anniversary we doused the classic, all-condition Barrage Cargo Backpack with Panaracer purple.

The signature, adjustable 5-point cargo net system allows additional space to hold shoes or a helmet when not in use. Featuring heritage materials like a DWR coated, abrasion-resistant nylon shell and a welded waterproof tarp liner, the Barrage Cargo Backpack will hold up on any commute.

Waterproof, fully welded main compartment liner, abrasion resistant nylon shell, a mini iconic seatbelt buckle, and an adjustable exterior cargo net, the Barrage is built to adapt to any environment or payload. A favorite of bike messengers the world over, rolltop bags give you extra room when you need to haul a ton of gear and fold over to keep everything inside protected from the outside world. Ideal for travelers, commuters who need to carry a variety of cargo or cyclists who get gnarly in all weather, rolltops get the job done.
