A must if you big hands.
This chalk bag does the job. Best of both worlds, when a bouldering bucket is too large and a standard chalk bag is too small for your hands. Use it for long pitches or any boulder session, it holds tons of chalk. The only down side I found is that the Arc'teryx logo is an iron on laminate, not stitching (embroidery) which I though was really lame (especially for the price),It will probably rub off after a while. Either way this is a stellar bag
