AI pick (line): Friction Labs Unicorn Dust

A fine-to-medium chalk with no fillers that coats evenly and stays dry, and the default pick of serious gym climbers and boulderers.

Not for: Climbers at gyms that ban loose chalk, or people who chalk up heavily and want the cheapest bulk option.

Metolius Super Chalk (line)

A dependable, widely sold loose chalk that suits high-volume use.

Not for: People with very sweaty hands who want a premium drying chalk.

Black Diamond White Gold (line)

A chunkier chalk that crushes to your preferred consistency and contains a drying agent.

Not for: Climbers who want powder-fine coverage straight from the bag.

Friction Labs Secret Stuff (line)

An alcohol-based liquid chalk that dries into a long-lasting base layer and is allowed in gyms with loose-chalk rules.

Not for: Climbers with cracked or sensitive skin that alcohol aggravates.

Composition: Magnesium carbonate with no or minimal fillers; any drying agent should be stated on the label Fillers reduce how well the chalk absorbs sweat and leave a slick residue.
Texture: Choose fine, chunky or super-chunky to suit how you chalk up Fine chalk covers fast, chunky chalk lasts longer in the bag, and texture affects dust and how long one dip lasts.
Gym rules: Check whether your gym requires liquid chalk or chalk balls Many indoor walls restrict loose chalk to keep dust down.
Skin tolerance: Prefer liquid chalks without harsh additives if your skin splits Alcohol and some drying agents aggravate split skin.

Many climbers put liquid chalk on first as a base layer and top up with loose chalk while climbing; liquid alone suits gyms that ban dust.
