Review on FrictionLabs Magic Chalk Ball 2.2 oz - Premium Chalk for Rock Climbing, Weight Lifting, Gymnastics, Bowling, Crossfit - Mess-Free Gym Chalk with Refillable Sock - No Fillers or Artificial Drying Agents - Enhance Your Performance by Jaleel Pruitt

As a student I usually prefer cheaper materials (eg Metolius chalk blocks) but I bought this for a friend and have been stealing his chalk ever since. I'm used to a thick, rough finish that needs topping up after every boulder wall climb, but the chalk in this bag is a fine dust that stays on your hands, which also means less lung strain (and my belayers seem to appreciate that). ). I no longer apply snow chalk while roped). At the same time, this chalk manages to keep your hands nice and dry without turning your palms into a cracked desert landscape. The only downside is the cost. While FrictionLabs is certainly more expensive than your regular block, I finally gave in and bought a packet of Unicorn Dust, which I feel is the closest thing to the chalk found in this Magic Chalk Sphere. I'm almost convinced this brand is worth a few bucks more and it looks like it's going to last longer.
