Made a ~50L pack liner out of 1.0 oz Dyneema to fit both my larger ULA Catalyst backpack and my Osprey Mutant 38 mountaineering backpack.

The design minimizes seams and uses folded darts to create a domed bottom and elevate the bottom seam by about 8 centimeters. Fully seam taped to keep water out.

The roll top uses 4mm foam as a stiffener and 3 snaps to hold the edges together before rolling. A 15mm (5/8") Magic buckle snaps together when closing thanks to small magnets in each half.

The Bio Hazard alerts anyone who dares to open the liner after sweating for several days in the great outdoors.

Total weight: 58gr.

The backpack pattern thus far in Seamly2D (https://seamly.io). Piece mode shows the 3 pattern pieces: Back, Bottom & Front. The Variables dialog window shows some of the parameters driving the dimensions of the pieces.

A 2nd packpack prototype, this time out of Tyvek. The final version will be made out of Ultra 200X which has no stretch and rather stiff. This prototype out of Tyvek shows how the final pack will "feel".

This version is deeper, taller and wider than the 1st version. I refined the bottom shape, which was relatively easy to do thanks to the parametric design in Seamly2D (https://seamly.io).

First prototype in fabric after drafting a pattern in Seamly2D (https://seamly.io/) based on the initial paper prototype. Made from recycled cotton. This prototype validated the pattern while also identifying several areas of improvement.

Starting to prototype my first backpack. Made the initial prototype out of paper to get a feel for the shape I have in mind. I find it easier to iterate with paper and tape before continuing the design in software and fabric.
