A reliable climbing chalk can make a major difference in grip, confidence, and overall performance. This Friction Labs chalk review takes a deep dive into one of the most talked-about chalk brands in climbing, known for its high-purity magnesium carbonate, superior moisture absorption, and long-lasting grip. Whether on an indoor wall or an exposed crag, Friction Labs claims to provide consistent performance with minimal fillers, setting it apart from cheaper alternatives.

After extensive testing across bouldering, sport climbing, and gym sessions, I found that Friction Labs chalk excels in moisture control and durability, making a noticeable impact in conditions where sweat or humidity typically cause issues. However, not every climber may need a premium-priced chalk, and the right choice depends on climbing style, preferences, and budget.

Why Friction Labs Chalk Stands Out
Unlike standard climbing chalks that may contain fillers, Friction Labs uses high-purity magnesium carbonate to enhance grip and longevity. The main benefits include:
- Superior moisture absorption – Keeps hands dry longer, reducing the need for frequent reapplication.
- Long-lasting grip – Stays on the skin better than standard chalk, meaning fewer dips in the chalk bag.
- Different textures to suit preferences – Offers fine, medium, and chunky chalk options.
- Cleaner formulas for indoor climbing – Liquid chalk options reduce airborne dust, making them ideal for gym environments.

For climbers who struggle with sweaty hands or humid conditions, Friction Labs chalk provides exceptional friction, often making the difference between sticking a hold and slipping off mid-move.
Friction Labs Loose Chalk: Choosing the Right Texture
Friction Labs offers three main loose chalk options, catering to different climbing styles and preferences.
Unicorn Dust (Fine Powder)
- Texture: Ultra-fine, silky powder with minimal clumping.
- Performance: Provides even application and absorbs moisture quickly.
- Best For: Climbers who prefer smooth, consistent coverage. Ideal for sweaty hands and humid conditions.
This chalk feels effortless to apply and provides instant dryness, but the fine texture creates more airborne dust, which could be an issue in indoor gyms.
Gorilla Grip (Medium Chunky)
- Texture: A mix of fine powder and small chunks.
- Performance: Breaks down easily in the hands for balanced coverage.
- Best For: Climbers who like a blend of smooth powder and tactile chunks. Works well for sport climbing and bouldering.
This was the best all-around option—chunky enough to feel satisfying but still smooth enough for quick, even application.
Bam Bam (Super Chunky)
- Texture: Large, breakable chalk chunks with minimal fine powder.
- Performance: Allows climbers to crush the chunks into their preferred consistency.
- Best For: Those who prefer less airborne dust and a customizable texture.
This chalk lasted longer on my hands compared to finer chalks, but it required more effort to break down before application.
Friction Labs Liquid Chalk: Secret Stuff Variations
Friction Labs also offers high-performance liquid chalk for climbers looking for less mess, longer-lasting grip, and improved hygiene.
Secret Stuff Original
- Texture: Creamy liquid that dries into a thin chalk layer.
- Performance: Provides a base layer that extends the time between reapplications.
- Best For: Climbers who want longer-lasting chalk, especially in humid conditions.
When I used Secret Stuff, I found that I didn’t need to chalk up as often, making it a great option for long sport routes or endurance boulders.
Secret Stuff Hygienic
- Key Feature: Infused with alcohol to sanitize hands while drying moisture.
- Best For: Climbers who train in gyms or want extra cleanliness.
This was especially useful in crowded gyms, where I wanted both good grip and germ protection from shared holds.
Secret Stuff Spray
- Texture: Liquid chalk in a quick-drying spray format.
- Performance: Applies faster and dries almost instantly.
- Best For: Climbers who need quick, no-mess application, such as in competitions or on-the-go sessions.
The spray was convenient, but I found it didn’t last as long as the original formula, making it better for short bursts of climbing rather than all-day sessions.
