I thought I'd post this here in case anyone would be interested. It's currently on Kickstarter and not yet funded. I pledged and figured maybe one or two of you guys would like this.

Readers digest version: A day pack made in the tradition of old school military seabags. Simple, one large compartment (21 liters in size) with one interior and one exterior small pouch and made with USA sourced material in California. Heavy duty construction including 1000 denier cordura exterior, ripstop interior, mil-spec webbing, double stitched, and featuring NO/ZERO zippers or plastic parts. The main compartment can be locked as well. Should last a lifetime.
