Description

Note - We're currently updating some of the labels within the digital delivery package to explicitly state "40L". The contents (material lists, sequence of construction, etc) are all correct and updated for the 40L build, but some spots may still say "34L". Sorry for the confusion! - RBTR

The 40L Mountain Flyer UL Backpack is a great place to start your DIY ultralight backpack journey. The backpack is light-weight and relatively simple to make. If made correctly, it is extremely durable on the trail.

This build features the classic Mountain Flyer silhouette, shock cord compressible side pockets, Y top strap, hip belt, front and side lash points, front mesh pocket with buckle closure, padded back panel, and whatever else you want to add/remove for your personal needs.

Large format template that you can take to any plotting service (like Kinko's). You can also purchase this FULL SIZE template pre-printed from us HERE.
Recommended materials list (*download HERE right now)
