Objective
The goal was to assess the chalk’s ability to enhance grip by improving friction between the climber’s hands and rock or gym holds. Superior grip is crucial for climbers navigating challenging routes, especially on smooth or overhung surfaces.

Method
We tested grip in both indoor and outdoor settings by climbing routes of varying difficulty. Testers completed climbing sequences without chalk to establish baseline friction and then repeated the routes after applying each chalk product. Grip performance was also evaluated on different hold textures, such as polished, rough, and sloping surfaces.

Outcome

• Friction Labs Unicorn 2.5 Oz excelled with a perfect score of 10 in grip, providing outstanding friction regardless of hold texture.
• Black Diamond Loose Chalk White and Friction Labs Bam 2.5 Oz received high ratings of 9, delivering consistent performance across climbing surfaces.
• The remaining products delivered satisfactory grip but didn’t match the standout performance of the top products.

Objective
The key focus was to measure the chalk’s ability to absorb sweat and maintain dry hands, particularly in humid or high-exertion scenarios. Moisture absorption directly impacts grip security and chalk effectiveness during climbs.

Method
We simulated both low and high humidity conditions using a controlled environment. Testers performed repetitive climbing sequences to generate sweat, and we noted the chalk’s ability to keep hands dry over time. Absorption capacity was also tested through direct application of water droplets to hands coated with chalk.

Outcome

• Friction Labs Bam 2.5 Oz and Friction Labs Unicorn 2.5 Oz achieved top scores of 9, demonstrating excellent sweat absorption even in humid conditions.
• Black Diamond Loose Chalk White scored an impressive 8, effectively controlling moisture under moderate sweat levels.
• Other options, like Metolius Super Chalk, showed limitations in high-humidity environments, with a lower score of 6.

Objective
This test aimed to determine how long the chalk remained effective on hands before requiring reapplication. Longer-lasting chalk minimizes interruptions during climbing and ensures consistent performance throughout a route.

Method
We measured how many holds testers could climb before chalk needed reapplication. Climbs were done on routes of similar difficulty and length to ensure consistency. Additional testing included exposure to temperature fluctuations and wear from holds to simulate real-world conditions over time.

Outcome

• Friction Labs Original Formula Alcohol, Friction Labs Bam 2.5 Oz, and Friction Labs Unicorn 2.5 Oz all scored a 9, maintaining their effectiveness across lengthy climbs.
• Liquid Grip Combo Kit held steady with a respectable score of 8, benefiting from its slightly thicker application.
• Metolius Super Chalk, though lasting reasonably well, lagged at a score of 8 comparatively.

Objective
To evaluate whether the chalk caused irritation, dryness, or discomfort after prolonged use, particularly for climbers with sensitive skin. Skin-friendly products are essential for climbers who chalk frequently during extended sessions.

Method
Testers used each product over multiple climbing sessions, noting any skin irritation or excessive dryness. Those with sensitive skin paid close attention to their hands’ condition, especially after long climbs or repeated use. We also examined product labels for harsh chemicals or skin irritants.

Outcome

• Liquid Grip Combo Kit and Friction Labs Unicorn 2.5 Oz scored the highest (8), demonstrating excellent skin compatibility while maintaining performance.
• Most other products, such as Black Diamond Loose Chalk White, had moderate performance with a score of 7, causing slight dryness.
• Friction Labs Original Formula Alcohol scored lowest (6), potentially due to its alcohol content, which can dry out skin after extended use.

Objective
Portability testing examined how easy it was to store, carry, and access the chalk during climbing sessions. Lightweight, mess-free, and space-efficient designs were prioritized.

Method
We tested chalk containers and packaging through standard climbing scenarios, such as packing gear, accessing chalk mid-route, and traveling with the product. Factors like weight, spillage, and ease of use were analyzed.

Outcome

• Lightweight and compact products like Metolius Super Chalk and Black Diamond Loose Chalk White achieved strong scores of 8, excelling in both storage and accessibility.
• The Liquid Grip Combo Kit received a score of 6 due to its bottle-style packaging being less convenient to carry and use mid-climb.
• Other products, including Friction Labs Unicorn 2.5 Oz, were satisfactory with a score of 7, balancing portability and functionality well.
