Mirage 40 by Gossamer Gear

Ships in 1-2 business days | Based in Austin, TX | Est. 1998
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
- Roll-top closure with two buckle closures on either side
- Side lace-cord compression system
- Multiple accessory attachment points
- EVA foam shoulder harness and waistbelt for comfortable carry
- Trekking pole attachment points
- Top carry handle
- Top compression strap
*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.
