Waldo
Description
The Safe Tech Waldo Harness is the world's most comfortable big wall harness. This is also the harness of choice for route setters, and anyone spending long days hanging in a harness. Our patented, adjustable-rise 3-D system creates the best-fitting harness in the world, and ½" (12 mm) thick slabs of foam contour around waist and legs for ultimate comfort. Monstrous components (5-5/8" (143 mm) waist belt and 5" (127 mm) leg loops) spread the load. Super-durable, closed-cell polyethylene foam with fleece lining also contributes to maximum comfort. The Waldo has diamond pattern body fabric and drop seat rear elastics, as well as dual front belay loops to minimize gear clutter. There are six gear loops on the medium and large, and five on the small. Sizing Note: When fitting the Waldo harness, the buyer should choose a size that will allow him or her to tighten the harness a few more inches from what feels initially comfortable. Wall climbers find that after a few days on a route, with a load of gear clipped to the harness, the ability to further tighten the harness is crucial.

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.” | 6 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. | No, 0 |

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) |

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
