Briggs and Riley Luggage

1000-denier Cordura nylon — the heaviest-weight commercial nylon fabric available, originally spec'd for military field equipment. The HDPE frame sheet is the same material used in bulletproof vests and cutting boards. Internal frame channels distribute load directly to the hip belt with the efficiency of a hiking pack in a daypack form factor. The compression-molded carry handle and bar tacks at every stress point are military construction. GORUCK guarantees the GR1 for life — the company was founded by a former Special Forces soldier who wanted the same gear quality he used in the Army to be available for civilians.

The body is Rugged Twill — a 14.5 oz oil-finish cotton canvas that Filson has used since 1897 for the Alaskan gold rush market. The oil finish makes the canvas water-resistant without a membrane; rain beads off the surface. The webbing straps and carry handles are woven nylon sewn with a harness-stitch pattern that can hold thousands of pounds without fraying. Solid brass hardware on the adjustable shoulder strap. The bag is made in Seattle, Washington. Filson's guarantee is unconditional — they will repair or replace any Filson bag regardless of age or condition.

Mystery Ranch uses 500D CORDURA nylon with the brand's proprietary FUTURA yoke — an adjustable spine-length system that positions the shoulder harness attachment at the correct point for any torso length using a single-tension pull. The sternum strap uses a quick-release buckle rated to 500 lbs. All main compartment zippers are double-pull YKK #10 — the largest, most durable YKK zipper available. Built in Bozeman, Montana for the US military (the company was founded by former DANA Design and Kelty engineers). The 3-Day Assault is issued to special operations units as their standard off-mission bag.
