The Duo is the minimalist, ultra-lightweight device for strengthening one finger... or two. Designed to isolate muscular and tendon work precisely, it features a 25 mm bi-finger grip and a perfectly calibrated mono-finger.

Its compact size fits in the palm of your hand, but it unfolds its full potential as soon as you hook it onto a branch, a quickdraw, or simply use it on the ground with a weight or a bungee cord.

Made from recycled rubber wood, it combines comfort, natural grip and environmental responsibility. The Duo is the tool of choice for climbers who want to progress finger by finger, with efficiency and simplicity.

Précis

Technical twin-finger socket (25 mm)

The Duo features a 25 mm-deep two-finger grip, ideal for training action pairs such as index-major or middle-finger-ring. It's perfect for preparing fingers for bi-finger arches, small flats or the fine rulers encountered on cliffs or hangboard.

Nomad

Minimalist, lightweight tool designed for mobility

With its small size and light weight, the Duo fits comfortably in your hand. It's quickly becoming a climbing bag staple. Whether you're warming up outdoors or training your fingers in your van, you can take it with you wherever you go.

Progressive

Multi-mode operation for all levels

The Duo can be used with bodyweight, suspended from a quickdraw or strap, or with a rubber band or disc for ground work. This allows you to adapt the load according to your level, your objective (strength / endurance / rehabilitation) and the context.

Comfort

Recycled material, pleasant feel, guaranteed longevity

Made from recycled rubber wood, it's environmentally friendly, durable and comfortable on the skin. Its rounded finish avoids painful rubbing and allows regular use without discomfort.
