First Impressions: Brand & Website
One thing that immediately caught my attention was Gekco’s branding and website. The logo looks fantastic with its vibrant green accents, and the overall design is sleek and modern.

It reflects the company’s eco-friendly ethos and innovative spirit. Their training clothes are also a pleasant surprise—stylish, comfortable, and durable, they’ve become an essential part of my climbing routine.
Loose Chalk: Pure & Eco-Friendly
Gekco’s loose chalk is made using a unique seawater-processed method, which yields a higher-purity magnesium carbonate compared to mined chalk. This means fewer contaminants and a more sustainable, renewable approach. Knowing that I’m using an eco-friendly product without sacrificing quality is a huge win.
- Performance: The fine consistency coats your hands evenly, improving grip and friction for those challenging crimps or long bouldering sessions.
- Purity: There are no fillers, just pure magnesium carbonate, so you get a chalk that won’t irritate your skin or leave any odd residue.

- Packaging: The paper bag is both recyclable and home compostable, which is nearly unheard of in a market flooded with plastic or bags that require industrial composting. With Gekco, you can toss the bag in your home recycling or compost bin without any guilt.
Comparing this to other mainstream brands, Gekco’s chalk is noticeably smoother, lasts longer on my hands, and doesn’t dry my skin as much. Plus, you’re paying less for a significantly higher-quality product.
Liquid Chalk: Pure Magnesium Carbonate & Alcohol
Gekco’s Liquid Chalk is just as impressive. While many brands add resins or thickeners, Gekco sticks to pure magnesium carbonate and high-grade ethanol.
- Zero Resins or Thickeners: This translates to faster drying times—just a few seconds—and a truly secure grip without any sticky residue.

- Skin-Friendly: Gekco uses ethanol instead of isopropanol, making it gentler on the skin. If you have any skin sensitivity or conditions like eczema, this formula might be a game-changer.
- High Chalk Content: Some cheaper liquid chalks add thickening agents that make it seem like you’re getting more, but in reality, you’re often getting less actual chalk. Gekco ensures every bottle is packed with as much magnesium carbonate as possible. Just remember to give the bottle a good shake before each use!
Why It Stands Out Against Other Big Brands
- Cost-Effectiveness: Not only is it cheaper, but you also get more chalk per dollar spent.
- Eco-Conscious: From the seawater-processed magnesium carbonate to the fully recyclable and compostable packaging, Gekco’s commitment to the environment is evident.

- High Performance: The chalk’s purity and carefully developed formulas deliver outstanding friction and comfort, so you can focus on sending your project rather than worrying about your grip.
After using Gekco Climbing Chalk, I’m convinced it’s a game-changer in the world of climbing essentials. The website is well-designed, the logo is sleek, the clothing line is top-notch, and most importantly, the chalk quality is unparalleled—at a price that makes sense for climbers on any budget. Whether you’re a seasoned climber or just starting out, give Gekco a try. You’ll be amazed at how it performs compared to other big brands, and you’ll be supporting a company that genuinely cares about the environment and its customers.
If you’re looking for the best chalk out there—one that’s cheaper yet more effective than the big-name brands—Gekco Climbing Chalk is the way to go. It’s become my go-to choice, and I’m sure it’ll become yours too!
FAQs
What makes Gekco’s Loose Chalk more eco-friendly than other brands?
Gekco sources its magnesium carbonate by extracting it from seawater rather than mining it out of the ground. This process produces a purer form of chalk with fewer contaminants and is more sustainable. Plus, the packaging is 100% paper-based, so it’s both home compostable and recyclable, reducing plastic waste in landfills.
How does Gekco’s Liquid Chalk differ from most other liquid chalk brands?
Many liquid chalks are loaded with resins, thickeners, or use harsher alcohols like isopropanol (IPA). Gekco uses only high-grade ethanol and magnesium carbonate—no extra additives—resulting in a faster drying time, better grip, and reduced skin irritation.
Is Gekco Chalk suitable for people with sensitive skin?
Yes. Since Gekco avoids harsh additives and uses ethanol instead of IPA, it’s generally gentler on the skin. Many climbers with conditions like eczema find it less irritating than standard liquid chalks. However, it’s always advisable to do a small patch test if you’re unsure.
How should I dispose of the packaging?
Gekco’s loose chalk bags are made from paper and can be placed in your household paper recycling or even in a home compost bin. Unlike many “compostable” or “recyclable” plastics, there’s no need for specialized industrial facilities—this ensures the bag won’t end up in landfill or incineration if disposed of properly.
