A cutting-edge ultralight framed pack

The Mirage 40L backpack is Gossamer Gear's largest fully waterproof backpack made with ALUULA® Graflyte™. This revolutionary fused mono-polymer fabric has no adhesives, no coatings, and no risk of delamination or frying. Graflyte™ is lighter, stronger, and more durable than traditional laminates. This adds up to a durable, fully waterproof, framed pack that weighs just 19.4oz (550g) or 18.7oz (530g) without the side compression and lightrek bungee attachment.

Gear up with integrated water bottle pockets that cinch tight, a stretch mesh front pocket for overflow gear, 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.

Features:

Carbon fiber X-frame made with solid 0.125-inch carbon rod connects to the hipbelt for optimum load transfer
Hip belt
Full interior taping for waterproof seams
Customizable back air space
Adjustable torso length and customizable shoulder harness for precise fitting
Integrated water bottle pockets with cinch top
Stretch mesh front overflow pocket

*Please note, the pack is shipped flat to prevent damage to the frame in-transit. Just clip in the attachment points to activate the X-frame system.

This pack is NOT submersible in water.
