MISSIONS

The BUILT TO SEND X3 pack is designed for longer multi-day alpine climbing trips (where bivvy or camping equipment is involved, for example), winter alpine climbing trips, extended multi-day hikes, winter ski-touring, and expedition use. Built for big missions where you need extra space for climbing equipment, cold weather clothing, or camping gear, this is the largest pack in our range. This is our most popular pack for high altitude or serious expedition use.

 

DESIGN

The unique BUILT TO SEND mono-shell design makes our packs almost indestructible. The main body is made from a single piece of expedition-grade composite VX42 X-Pac fabric leading to an almost seamless design. The only way of breaking a BUILT TO SEND pack is to tear though one of the toughest materials on the planet. The fabric is 100% waterproof, making our packs extremely weather resistant in rain and snow.

 

Our contoured shoulder straps and back panel are engineered from a proprietary foam (we developed our own 10 mm thick physically cross-linked polyethylene foam) based on a type used in fighter pilot seats. The properties of this foam give it excellent load spreading capability for shoulder straps and belt pads (X2 and X3 packs), and make the back panel forgiving of poor packing when fully loaded. Shoulder and hip pads are low-profile, for harness compatibility during rock and ice climbing.

 

Our hardware is custom-designed and engineered from aerospace-grade aluminium, with a hard-anodized coating for extreme durability. Our seam allowances are almost twice the industry standard, and we triple stitch structural seams using V92 bonded polyester thread, exceeding the military specification for safety-critical equipment.
