While our bags are weather-resistant, we also understand that sometimes you need even more protection against the elements. Our Rainfly ensures your gear stays dry in the gnarliest of storms! Made with lightweight and durable 50D ripstop nylon, our new and updated Rainfly features several attachment points to secure the Rainfly to your bag (our Rainfly loves high-speed motorcycle rides) and an integrated stuff pocket for easy storage. The Medium Rainfly fits all sizes of the PRVKE, the NIMBUS, and the STRATUS, while the Large Rainfly fits the FERNWEH, the TRANSIT Travel Backpack, and all sizes of the CARRYALL Duffel.
