Friction Labs Chalk

The textures refer to the consistency of the chalk. Unicorn is a fine powder that coats hands evenly, Gorilla Grip is a mix of powder and small chunks for a balance of coverage and texture, and Bam Bam consists of large, chunky blocks that you can break down to your preferred consistency.

High-purity magnesium carbonate is free from unnecessary fillers and drying agents. This results in better moisture absorption and friction, meaning you don't have to re-chalk as often during a climb.

It largely comes down to personal preference. If you like a consistent, smooth coating, start with Unicorn. If you prefer having something to squeeze or want a bit more tactile feedback on the rock, opt for the chunkier Gorilla Grip or Bam Bam.

If you climb multiple times a week, the 12oz bag is the most economical choice. The 2.5oz size is best for travel or testing a new texture, while the 6oz bag is a solid middle ground for occasional climbers.

Yes, it is effective for both. Because it is designed for high-performance moisture absorption, it provides the same reliable grip whether you are working a short, intense bouldering problem or a long, endurance-heavy sport route.
