Climbing Chalk & Chalk Bags

Climbing chalk (magnesium carbonate) absorbs sweat, increasing friction between hands and holds. Studies show it improves grip strength and hang time, though some debate exists about its friction benefits. Most climbers rely on it to combat sweaty palms and enhance performance. 

Loose chalk is powder applied directly to hands, while liquid chalk (mixed with alcohol) dries quickly, coating skin evenly. Liquid chalk lasts longer and reduces airborne dust, making it ideal for gyms or sensitive environments. 

Opt for a durable bag with a secure closure (drawstring or buckle) and a brush loop. Size depends on use: smaller bags for sport climbing, larger ones for bouldering. Belt attachment should fit snugly around your waist or gear loops. 

Reapply when hands feel moist or lose grip. Over-chalking creates clumps—use sparingly. Liquid chalk typically requires fewer reapplications than loose chalk. 

Empty residue, hand-wash with mild soap, and air-dry. Avoid machine washing to preserve waterproof liners and stitching.
