PACT™300 and PACT™100 are both densely woven fabrics comprised of high tenacity Nylon 6.6 yarns with a double rip-stop construction, and feature a durable water repellent (DWR) face-coating and a water impermeable 25 micron TPU coating on the inside.
PACT™ 300: Using 300 denier yarns and weighing 177g/m² this is the strongest, most abrasion and puncture resistant yet pliable PACT™ fabric. A single layer is used throughout the main body of the Tupilak packs with a double layer providing additional reinforcement and structure in the base. It is also used in strategic areas for additional reinforcement.
PACT™ 100: Using 100 denier yarns and weighing 115g/m² this is the lightest PACT™ fabric. For its incredibly low weight it provides exceptional tensile strength but being lighter it is solely used in the upper body and Cowl of the Tupilak packs as well as internal roll-top closure. An uncoated version of this fabric is also used as an internal lining fabric.

Grappler™ Buckle:

The Grappler™ is a durable, one-handed pack closure system. Its unique buckle design features an easy to grab ‘lobster tail’ and pincer hook which provides a fail-safe ‘grapple lock’ on to the cowl’s integrated webbing spine. Purposefully designed with an angled spine, the Grappler™ buckle lies flush against the top of the pack whilst remaining easy to release with or without gloved hands.

Hammerhead™ toggles:

The Hammerhead™ side compression straps have been designed to be fully removable and low profile. At one end, a ‘Hammerhead’ retainer sits flush against Daisy Chain webbing whilst at the other, a simplified version of the Grappler™ buckle provides a secure yet quick release function.

Shockcord System:

The shock-cord system provides additional functionality for carrying items on the outside front of the pack such as crampons or a sleeping mat.
