MISSIONS

The BUILT TO SEND X0 pack is an ultra-minimal pack for those who have their gear really dialed in. Built for fast-and-light two-day missions in alpine environments, or ultralight two-day ascents on rock, this pack also works well as a cragging day pack or for fast-and-light weekend hikes. This is our most popular pack with Alpine Guides.

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. Load-rated webbing is bar-tacked for extreme strength. Our unique load-rated haul-system avoids “clusters” on difficult belays with bucket-style belaying (rope flaked directly into pack), allows kit management on tight bivvy ledges and is haul-rated for chimney pitches of when back-cleaning on steep ground (pack can be used as a small haul bag).

BUILT TO SEND packs represent an extreme design-optimization point, stripped down and refined to achieve the epitome of bombproof-yet-ultralight. We hand build our packs in limited numbers in Great Britain, to exacting engineering standards under an ISO 9001 quality system. Your BUILT TO SEND pack has been built without any compromise on quality. It’s the finest engineered and strongest pack on planet earth.

FABRIC. 100% expedition-grade VX42 X-Pac composite fabric.

CONSTRUCTION. Unique mono-shell construction technique with almost seamless design.

HARDWARE. Hard-anodized aerospace-grade aluminium hardware.

FOAM. Proprietary BUILT TO SEND 10 mm foam—developed from that used in fighter pilot seats.

SEAMS. Structural seams triple-stitched with V92 bonded polyester thread—higher specification than used in safety-critical military applications.

THREAD. High-strength points (grab-handle/haul loop, shoulder straps, and haul system) bar tacked with V92 thread for load-rated strength.

LOAD RATING. Our packs are so strong we rate them to any practically achievable load.

QUALITY SYSTEM. Individually hand built in Great Britain under an ISO 9001 quality process.
MONO-SHELL CONSTRUCTION. Unique, almost seamless design for near-indestructibility

OVERLOAD CAPABILITY. Pack more into base camp or the start of a route, then reduce pack volume by approximately 1/3 for climbing; crossed top compression straps secure large loads.

X-FOLD TOP WITH G-HOOK CLOSURE. Fast access; extremely weatherproof; avoids stress-points in conventional roll-top designs

HAUL-SYSTEM. Our unique top band with integrated load-rated haul-tabs has been designed for big-walling. This system allows the pack to hang “bucket style” from hanging belay stances and cramped bivvy ledges, so you can easily manage your kit and avoid “clusters” by belaying the lead rope or “tag-line” (when big-walling) directly from the pack. The pack is haul-capable (and bombproof enough) for short chimney pitches or when back-cleaning on steep ground—simply clip into the four haul tabs and cut the bag loose.

INTERNAL ZIPPER POCKET. Large internal zippered pocket for keys and valuables.

LOAD-SPREADING SHOULDER STRAPS. Engineered from proprietary 10 mm foam; ultra-comfortable even under heavy loads; contoured for rock and ice climbing.

FOAM BACK PANEL. Super-comfortable proprietary 10 mm foam, developed from that used in fighter pilot ejector seats.

WIDE WAIST BELT. Wide 50 mm webbing for comfort; this is one of only two places on the pack where we use a plastic side-release buckle to release quickly in an emergency.

WAIST BET PADS. X2 and X3 packs have non-removable pads for comfort and stability with heavy loads; pads are low profile for rock and ice climbing.

STERNUM STRAP. Removable; elastic shock absorption; the second of only two places on the pack where we use a plastic side-release buckle to release quickly in an emergency.

GRAB-HANDLE/HAUL LOOP. Ultra-strong, wider-than-normal, load-rated version of the conventional system.

DOUBLE REINFORCED BASE. Two layers of expedition grade composite fabric make our bases extraordinarily tough.

ICE AXE BLADE RETAINER. Tough 50 mm webbing loop to secure ice axe blades.

UNIQUE ALPINE CUSTOMIZATION SYSTEM. Hard-anodized aerospace-grade aluminium tri-glides give bombproof attachment points to transform your stripped-down climbing/big-wall pack into a fully loaded winter/alpine/ice-climbing pack; customize to the exact requirements of your mission (compression; crampons; ice axes).
