Arc’teryx’s Ion Lightweight Chalk Bag hones in on function, with a streamlined design and durable construction. Easy to use and providing long-lasting reliability, the bluesign approved siliconised fabric is lightweight yet hardwearing, and the spiral closure has a straightforward drawcord system. It opens wide for quick access to chalk and prevents spills and leakages when closed. The Ion features an elastic brush loop and comes with an adjustable waist belt. The two sizes mean you can choose the one that suits your chalk needs best.
