Overview
Slide Bloc buckles set the leg loop fit on this men's harness, and two-part webbing adds strength and abrasion protection where the harness takes wear. Four gear loops and a haul loop handle the rack and trailing gear.
Adjustability and a clear loop layout suit climbers who split time between the gym and the crag. The listing gives no waist size range or strength figure, so sizing needs a look at the maker chart.
Who it's for
Climbers who change between indoor walls, bolted routes and longer outdoor days will use the adjustable leg loops and the extra gear loops. Anyone who wants an ultralight alpine harness, or who is not a Medium, should compare other sizes and models.

Performance notes
A harness spreads load through the waist belt and leg loops, so a snug waist and well-set leg loops matter more than any single feature. Layering clothes changes how much leg loop adjustment is needed, which is where the slide buckles help.
