Overview
Performance climbing harness
Features / Notes
Approved by Adam Ondra – Mammut athlete, multiple World Champion and the first to make history climbing Silence (9c).
This ultralight harness gives you total freedom of movement and support – whether competing at the Olympic level or tackling tough routes at your local crag.
With just two gear loops and one buckle for adjustment, the harness has been stripped down to the bare essentials for exceptional lightness and performance. An extra-strong Dyneema belay loop reduces bulk.
Ondra states the harness provides “excellent hanging comfort with so little weight” and is “hands down the best climbing harness”. The Adam Ondra Sender Light Harness is made for greatness.
