When your backpack needs total protection from the elements, look no further than the ultra-packable waterproof Outdoor Rain Fly. Constructed from waterproof Terra Shell™ 50D recycled ripstop nylon with a 2,000mm hydrostatic coating and fully-taped seams, the Outdoor Rain Fly keeps your pack dry in the gnarliest of downpours. A cinchable elastic cord around the perimeter of the rain cover ensures it fits tightly around your bag, and laser-cut holes at the bottom allow any moisture that seeps in to quickly drain. When not in use, the Outdoor Rain Fly stuffs into a zippable mesh pouch that can hang on outside of your bag to dry out. Fabrics are Bluesign-approved and PFAS-free. Fair Trade Certified and 100% carbon neutral.
