Materials

SDRT Grade Dyneema® flexible composite fabric

SDRT Grade Dyneema® flexible composite fabric is a waterproof, lightweight and highly durable laminate, made from non-woven UHMWPE and high performance coatings. Dyneema is about twice the strength of Kevlar or around half the weight, this makes it ideal for ultralight outdoor and mountaineering gear, including high performance equipment such as body armor and experimental UAV designs. It is resistant to UV light, is a ripstop and is 100% waterproof.

Dyneema® can be crinkled, or rolled up without losing structural integrity. The challenges of working with such an unforgiving material and its cost restricts mainstream use.

Dyneema® starts out a little stiff and takes about three solid trips for the material to reach a crumpled, lived-in state.

We chose an SDRT Grade 50 denier polyester face for better abrasion resistance. A raw, slightly translucent version is used in the inside-lid pocket of the D3.

YKK Zippers

We use water resistant YKK Uretek zippers throughout the duffel.

Made in Japan & the USA.

Petzl Carabiners

Petzl Ange S carabiners connect the D3 strap to the duffel. Designed for mountaineering and multi-pitch climbing where weight reduction is key — each is only 1 oz. On the duffel they enable a versatile range of carrying styles (the straps are not designed to support an adult human weight). The compact shape of the nose is designed to optimize clipping and unclipping and has a hole that allows ice, snow or dirt to be cleared out. The strap loops are engineered to sit snugly in the carabiner’s rope loop.

We use matte black Petzl locking carabiners on the D3 Raw.

Made in France.

Pamir Mountain Stone

Pamir River Stone

The outer zip pulls on the D3 Traveller, and all our pouches include a pebble from the tributaries that flow through the Pamir Mountains, in the Gorno-Badakhshan Autonomous Region of Tajikistan, one of the world’s great mountain ranges, and home to a SDR Traveller R&D site. In a world well travelled, it remains one of the most remote and geo-politically interesting parts of the world - bordering Afghanistan, China and Kyrgyzstan.

Hand picked and precisely drilled they are smooth on the hand, cool to the touch. For a number of years we’ve collected stone on our travels — a tangible and present reminder of where we’ve been and where we plan to return. Each stone tells a story: a border crossed, a mountain climbed; a check-point negotiated; journeys well travelled. You might find it curious to add stone to ultralight luggage (each adds less than 0.1 oz), but these will add a spring to your step.

Airplane Grade Aluminium

The loop and tri glide on the D3 strap are precision machined from a solid block of aircraft grade aluminum (6061-T6), before being plated with a durable anodized finish.

Made in USA.

Silver/Copper/Nickel

Silver, Copper, Nickel coated fabric

The 1M Hauly Heist uses a double-walled silver/copper/nickel coated ripstop, to minimise the risk of RF tracking for any electronics placed inside the pouch. The silver coated hook and loop is optimised for conductivity, making it ideal for RF shielding. Tested in accordance with modified Mil Standard 285, it can be used repeatedly with minimal shielding degregation. Is RoHS compliant.

Made in the USA.
