Ocun Webee Bigwall Rock Climbing Harness - 7 Gear Loop Half Body Safety Harness Review (2026)

What it's built for

Ocun designed the Webee Bigwall as a dedicated harness for aid and big wall climbing, where you spend hours hanging in the harness and need somewhere to organize a large rack. It is a half body design with adjustable leg loops, which keeps it familiar to climbers used to a standard sport or trad harness rather than asking them to learn a full body system. The harness carries CE and UIAA certification under EN 12277 Type C, the standard for climbing harnesses, and is made in Czechia, where Ocun manufactures its climbing hardware. That background matters for climbers who want a harness built by a company with a long track record in technical alpine and big wall gear rather than a generic import.

Gear loops and organization

The headline feature is 7 gear loops plus 2 ice clipper slots, giving you a lot of places to rack cams, nuts, pitons, and other hardware across long aid pitches. That loop count matches the Trango Double Rack chest sling in this same lineup, though the Webee puts everything on one integrated harness instead of stacking a separate chest sling over your waist harness. The haul loop is rated to 9kN tensile strength, and the harness includes 2 belay and tie in loops, both standard features for a harness meant to anchor and haul gear on multi-day walls. Spreading a rack across seven loops also helps you keep cam sizes and hardware types separated so you can find the right piece quickly mid pitch.

Materials and comfort

Ocun uses what it calls WeBee technology in the webbing, which the brand describes as light, breathable, durable, and machine washable, a useful detail for a harness that will get sweaty on long days and needs to be cleaned without falling apart. The 4 slide lock buckles are stainless steel SS-420J2, sized at 28mm and 20mm, and include a wear and tear indicator so climbers can check the buckles for damage over time. In the XS-M size the harness weighs 530 grams, and the L-XL size weighs 570 grams, both fairly typical for a big wall harness with this much hardware. Being able to wash the webbing is a genuine advantage after a multi day wall push where sweat and dirt build up fast.

Sizing and fit

The XS-M size fits a 68 to 95 cm waist and 50 to 68 cm leg loops, while the L-XL size fits an 85 to 110 cm waist and 55 to 73 cm leg loops. That is a wide range within each size, which should cover most adult climbers, but as with any harness it is worth checking your own waist and thigh measurements against these ranges before buying rather than guessing from a shirt or pants size. The leg loops adjust, which helps on wall days when you are wearing different layers depending on weather, from thin approach clothes to a warmer layer for cold belays or bivy nights on the wall.

Who should buy it

This harness suits climbers heading onto aid routes or big walls who want a proven half body design with enough gear loops to rack a full aid kit without a separate chest sling. It is not the harness to learn multi-pitch trad on, since the extra loops and big wall focused features add weight and bulk that sport or single pitch trad climbers do not need. Climbers already comparing options like the Black Diamond Long Haul or Petzl Corax for a wall trip should also put the Webee Bigwall on that shortlist given its loop count and European build quality, especially if they value a washable harness for multi day trips.
