With offcuts from our AK rucksack fabrics going to waste on the cutting-room floor, we decided that chalkbags were a much better solution than landfill. Which is why crux chalkbags come in a choice of two ridiculously overspecified materials – Kevlar® and Dynatec®.

Both models close at the neck with a sleeve of silicon-coated nylon, which is actually taken from our X2 tent flysheets. Easy to slip your hand in and out of, the nylon doesn't delaminate and won’t gather chalk dust. The neck closes slickly with a Dyneema® draw-cord that absorbs neither water nor chalk dust and will certainly never break.

The stiff Kevlar fabric means this chalkbag keeps its shape all the time – perfect for those who need to quickly thrust their entire hand in for psychological support as well as a thorough plastering
