Many lightweight thru-hiking packs either don't have hip belt pockets, or if they do, they are too small to hold much else than chapstick.

I wanted to create a pouch that was large enough to hold an iPhone X and a granola bar.
After sketching and making paper models, I drew up the pattern panels onto a Fusion 360 sketch and used parametric dimensioning, so that the pattern can be easily scaled to fit different phone sizes.
Designing for domestic manufacturing, where labor is expensive, sewing and assembling the pouch required as few steps as possible.
Because I chose X-Pac VX21 Terrain, a premium highly durable and waterproof fabric, the pattern needed minimal material waste.
The final pattern requires two panels and five sewing operations.
