The full body harness Master Up Al Lock features a revolutionary waist adjustment system, allowing it to cover a wide range of sizes.

The chest part of the harness is equipped with a sewn-in lightweight compact blocker Chest Up, designed for professional use in rope access systems. Chest Up is equipped with a unique rotating swivel. Another very interesting and useful advantage can be found in the positioning loops, where the user can adjust the loop position (EN 358) exactly according to their needs.

The harness is very comfortable not only because of the excellent waist system but also thanks to the reinforced leg straps.

A broad versatility is also provided by the variable slot system (combined with a repka) on the back padding. For storing smaller items (e.g., knife, etc.), there are slots in the shoulder padding.

Reflective elements, 6 classic material loops, and a haul loop are included.
Adjustment via Al quick-release buckles. Loose ends of straps can be secured with the SB system (Clip Smart). The attachment points are made of aluminum, except for the rear fall arrest point, which is used exceptionally. This point is stored in a cover pocket and only pulled out when needed. To reduce weight, it is textile.
