I only use the best materials I can get my hands on.

Ultra 200, 400 and 800 from Challenge sail cloth. (119gsm, 158gsm, 274gms)

Ultra is made of woven UHMWPE (Ultra High Molecular Weight Polyethylene), the generic name for unbranded Dyneema fiber. Its insanely tough and highly water proof. Its also the only fabric I seam tape when making a pack. This adds to seam strength and waterproofness. The higher the number the thicker the fabric. Ultra 200 is great from light weigh pack, ultra 400 is used for high wear areas or main body's on larger pack and the 800 is total over kill for most applications but i still use it on the bottom of the larger packs or if you wanted a truly bombproof pack.

210D HDPE Gridstop. 

It has a base nylon fabric with 210 denier fibers with an HDPE fiber reinforcement grid to add tear and tensile strength. It has a softer feel and not as stiff as the other fabrics i use making it a great choice for pockets.

Colours Burnt Orange, Charcoal Gray, Dark Olive, Moroccan Blue, Black


420D ROBIC® At 207g / sqm its not the lightest but its worth the extra grams for its toughness. I use this for the majority of the backpack bottom, backs and strap attachment points. Also good on high wear part on bikepacking gear.

X-Pac VX21, VX15 and V15 are lightweight yet super tough fabrics, ideal for backpacks and bike bags. Stiffer then other pack fabrics it helps the packs retain their shape. Also extremely waterproof.


LiteSkin LS21 is light, waterproof and tough. Only comes in gray but it looks very smart.


I use heavy wearing 1000D coated nylon for the contact points on my bike packing gear.
