The Tendon Jammy is a featherweight, unpadded harness built for via ferrata, glacier travel and alpine days where every gram counts. A single universal size adjusts to fit a wide range of body shapes, so it works as well for a mixed group on a via ferrata outing as it does stashed in an alpine rack for emergency use.

A reinforced tie-in point and a colour-coded belay loop keep clipping in straightforward even with gloves on, and a single gear loop carries the essentials without adding bulk. Its minimal, unpadded construction packs down small, making it a natural choice for ski mountaineering, climbing walls and climbing schools as well as classic via ferrata routes.
