Details on the YY Vertical Duo
The Duo is a featherweight climbing accessory specifically designed for training. It isolates muscles and tendons from a finger with the 1-fingerhole or two fingers with the 2-fingerhole.
It can be used with a rubber band, a weight, or just body weight. With its smooth design made from recycled rubberwood, the Mono offers a soft-touch surface that climbers will love for its comfort and grip.
We can recommend the Linebreaker BOLT as an accessory: you can use it to lift weights from the ground.
