A used Komet Miller Butterfly 2 Harness 

Light and ergonomic, the Butterfly II positioning belt has been designed to meet the requirements of the tree pruning professionals.

This harness is particularly adapted to operations where the tree pruner is continually moving around the tree.

Combining technical features (side and front anchorage points) with comfort of use (large back pad and independent leg straps) this harness is particularly adapted to operations where the tree pruner is continually moving around the tree.

Leg straps, front anchorage straps and seat straps are also available and interchangeable. 

Excellent Freedom of Movement : The lightweight materials and ergonomic design enhance manoeuvrability and are particularly adapted to operations where the tree-pruner is continually moving around the tree.

Greater Comfort : A wider, more robust padded belt and padded leg straps ensure good support and a more comfortable fit. The rigid seat strap option increases comfort during prolonged work in suspension on the Butterfly belt. 

Greater Versatility : The leg straps, seat strap and front anchorage parts are all interchangeable on the Butterfly II tree-pruning belt, enabling the climber to easily adapt the belt to a particular work site. 

Features:

• Tree pruning belt with padded belt and removable legstraps
