The Arcteryx C40 Chalk Bag has been redesigned with new materials. Made with Burly Double Weave, the four-way stretch C40 Chalkbag is supple and tough. This Arc'teryx climbing accessory comes in two sizes (c40 and c80) to accommodate different hand widths and chalk needs. Soft polar fleece lines the inside so you won't scuff your knuckles reaching for chalk, and an easy drawcord closure keeps chalk in and protected. Useful features include an injection molded belt attachment/ slider, waist belt to keep it close, convenient brush holder, and a bottle opener for afters. The Arcteryx C40 Chalk Bag sturdily holds your chalk in a surprisingly supple shell.
