Why the new Nano Glass skinfile is a must have
If you climb a lot, you’re constantly dealing with rough holds, chalk and friction and your skin takes a beating, gets dry, dull or even cracked. With our KletterRetter Nano Glass skinfile you have a low-maintenance, long-lasting tool that gently removes dead skin cells and smooths the surface of your skin. Perfect for hands, feet or even rough spots on elbows and knees.
What makes the Nano Glass Skinfile special?
- Finely structured nano glass surface:
The special glass texture provides gentle but effective exfoliation. Unlike rough metal or sandpaper-style files, the Nano Glass file doesn’t scratch, it glides in a controlled way over the skin and removes callused, rough areas without sharp edges. - Skin-friendly and suitable for sensitive skin:
The ultra-fine surface significantly reduces the risk of over-irritation. This means you can treat sensitive areas without putting unnecessary stress on your skin. - Durable, hygienic, easy to clean:
Glass does not absorb moisture and is extremely robust. After use, simply rinse under running water and let it dry, that’s it. No roughening, no wearing down like with classic files. - Versatile:
Whether it’s callus on your feet, rough patches on your hands or dry areas on elbows and knees – the Nano Glass file works wherever you want to gently remove excess, callused skin.
How to use the Nano Glass Skinfile
- For climbers, the Nano Glass file works best on dry skin
Filing on dry skin gives you more control, prevents over-filing and keeps the callus structure strong, which is ideal for climbing. Only in rare cases (for example very thick callus on the feet) is a brief softening useful. - File gently
Move the Nano Glass skinfile over the affected areas using light pressure. Work in small, controlled movements, circular or in one direction, without “scrubbing”. - Smooth and stop before it’s too much
Only file until the skin feels smooth and rough edges are gone. You shouldn’t feel redness or burning, less is more here. - Clean
After use, rinse the skinfile thoroughly with warm water. If needed, you can also clean it with mild soap and then let it dry completely. - Care
Afterwards, apply a suitable care product, for example KletterRetter Hand Cream or KletterRetter Repair Balsam. This supports the regeneration of the skin and helps prevent new cracks and dry spots.
Why the Nano Glass skinfile fits perfectly with KletterRetter
At KletterRetter it’s not just about chalk, tape and performance, we think about skin care as a whole. Frequent bouldering or climbing creates rough patches, small cracks and stressed skin. Your hands and feet are your direct connection to the rock or wall, and they deserve proper attention.
This is why we developed the Nano Glass skinfile as the perfect addition to our existing care range:
- It gently removes old, callused skin and prepares the skin perfectly for follow-up care with cream or balsam.
- It reduces the risk of calluses, splits and annoying “edges” on your fingertips that can quickly become a problem when climbing.
- It helps you keep your skin in the exact condition you need for climbing: robust, but not too thick; smooth, but not slippery.
Practical tips for use
- After hard bouldering or climbing days:
Gently remove dead skin and rough ridges with the Nano Glass skinfile. Then wash your hands and apply KletterRetter Hand Cream or Repair Balsam. - Before taping:
Quickly smooth the area with the skinfile. Tape adheres better and forms fewer wrinkles on smooth, clean skin. - For feet:
Regularly remove light callus on your feet. This helps prevent pressure points in tight climbing shoes while still keeping a functional protective layer. - Consistency instead of “extreme sessions”:
It’s better to file a little more often than to go all-in once in a while. This keeps your skin stable and minimises the risk of painful cracks.
Conclusion: Small tool, big difference
The KletterRetter Nano Glass file is not a luxury gadget, it’s an essential care tool for anyone who takes their skin seriously. Especially as a climber or boulderer you know: skin often decides whether you can enjoy a session or have to stop after a few tries.
With the Nano Glass skinfile, you bring your skin structure under control; gently, effectively and long-term. Combined with our care products like Hand Cream and Repair Balsam, you have everything you need to keep your skin ready for long sessions and hard projects.
