Alchemized with waterproof ALUULA Graflyte V52, this revolutionary fused mono-polymer fabric has no adhesives, no coatings, and no risk of delamination or fraying. This innovative manufacturing method delivers a framed pack weighing just 19.4 ounces, or just 18.7 ounces when the removable components are stripped away. Gear up with integrated water bottle pockets that cinch tight, a stretch mesh front pocket for overflow essentials, and a roll-top closure with a two-way connection point to keep your essentials secure and accessible. The new carbon fiber X-frame provides ultralight structure and direct load transfer. The Mirage 40 isn’t just lighter, but the lightest 40 L pack available.
