Jay IV
Description
All-round climbing harness for gyms, crags, and via ferratas.
The JAY is a tried-and-tested, all-round harness for use when climbing in the gym and at the crag as well as on via ferratas and when mountaineering. Now in its fourth generation, the harness is more comfortable than ever. This is partly thanks to the butterfly shape of the waist belt, which optimally distributes the load and offers good hanging comfort. The hip padding can be moved using the center fit construction for optimum adjustment and positioning. The two parallel tie-in points are very soft and smooth. Together with the enlarged upper tie-in point, this enables simpler tie-ins and offers greater overall comfort. The enlarged central ring also provides additional comfort when standing and belaying. The O-shape of the JAY makes it particularly ideal for climbers whose waist and hips are of a similar size.
- Center fit construction: sliding waist belt padding that can be centrally positioned enables optimum harness adjustment
- Butterfly shape for increased hanging comfort and optimum load distribution
- The hip belt and leg loops become higher with increasing size
- Parallel tie-in points on the hip and leg loops with textile abrasion protection made from an HMPE-polyamide blend
- bluesign® PRODUCT
- Fully opening, self-locking Slide Block buckles in the waist belt and leg loops, which make it easier to put on when wearing skis or crampons

Gear LoopsNumber of Gear LoopsGear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common. 
0 - 1 Gear LoopsMost often on full body harnesses or guide/gym style harnesses. 2-3 Gear LoopsMostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority. 4 - 5 Gear LoopsThe standard/most common number for climbing harnesses. Perfect for sport and trad. More Than 6 Gear LoopsDesigned for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear. Worth ConsideringOccasionally, the number of gear loops will change on a harness model depending on the size. There could be 7 gear loops for the med/large but only 5 gear loops for the xsmall/small. In this case we list the highest number for the filters, and then write an explanation on the product page like, “Size S/XS can only fit 5 gear loops.” | 5 Gear loops |
Ice Clip SlotsIce Clip SlotIce clipper slots are made to fit a carabiner that holds ice screws. These slots are generally only used by ice climbers but there is no disadvantage to having them on your harness. 
Less than 40% of harnesses will have ice clipper slots. And those harnesses will usually have 2 or 4 slots, often located next to, or between, the gear loops. | Yes, 2 |
| Belay / Tie-In | One Loop |
| Waist Buckle Type | Quick Adjust |
| Leg Buckle Type | Quick Adjust |

Haul LoopHaul LoopTrad climbers often look for a haul loop as they're intended to haul a rope (second line) or pack (while you climb the chimney). 
A haul loop can also hold shoes or other accessories. Although not the intended use, it is also commonly used to hold a chalk bag. | Yes (0kN) |
