The Duo is a super - lightweight climbing accessory crafted specifically for training. It enables you to focus on the muscle and tendon development of one or two fingers, with a 25mm - deep two - finger grip. This amazing tool gets your fingers ready for all types of gripping challenges! You can use it as a light - load training device with an elastic band or a weight. Or, simply hang it on the first quickdraw or a tree and use your body weight. Made from recycled rubber wood with a sleek design, the Duo offers a soft - touch surface. Its comfort and excellent grip will surely win over climbers. Dimensions are 8cm x 5.5cm x 3cm, and it weighs just 50g.

Using the Duo is easy. If you want to use it with an elastic band or a weight, just attach them to the Duo to add some extra load for your fingers. Or, you can hang it on a quickdraw or a tree branch and let your body weight do the work. When using it, make sure your hands are clean and dry to get the best grip. Don't over - train at once; start with a few sets and gradually increase the intensity. To keep the Duo in good condition, store it in a cool and dry place. Avoid exposing it to direct sunlight for a long time, as this may damage the recycled rubber wood material. If it gets dirty, you can gently wipe it with a damp cloth.
