Cotopaxi’s Allpa 42L is the largest of the brand’s range of rugged, go-anywhere travel bags. The outer shell of the Allpa is made of tough & weather-resistant TPU-coated 1000D polyester paired with 1680D ballistic nylon paneling. It will fit in the airline overhead and keep gear dry squeezed into the cargo-hold of a puddle jumper. With multiple carry options, you can run it as a duffle, pack, or (large) brief. Available in black or blue.
