How to use DMM Harness, warning, inspection and maintenence with instructional pictures
The Viper is officially retired.You've found a page of history! The Viper is no longer produced by DMM and it is not available to buy from major online retailers. You can still check out all the specs and claim your ownership.
If you want an adjustable padded harness, but one pitched perhaps at a more affordable level, then the Viper is an excellent choice.
This is a great value, well designed, all rounder suitable for the full gamut of climbing disciplines. Use it down the wall, out on the crag; the adjustable leg loops also make it a good winter harness.
It has many of the features of the top of the range harnesses, but we have simplified the design slightly. For example, there is no floating waistbelt, and there are 5 gear loops instead of 7.
It does have the Slide Lock buckles though, which we’ve given a rounded off, low profile shape to reduce ‘snagability’.
Newcomers will be pleased to note that it is available as part of a Starter Pack, which includes all you need to get going, namely a belay device, a Belay Master 2, a chalk bag and chalk ball.

Number of Gear Loops
Gear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common.
0 - 1 Gear Loops
Most often on full body harnesses or guide/gym style harnesses.
2-3 Gear Loops
Mostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority.
4 - 5 Gear Loops
The standard/most common number for climbing harnesses. Perfect for sport and trad.
More Than 6 Gear Loops
Designed for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear.
Occasionally, 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.”

|Ice Clip Slots|
Ice Clip Slot
Ice 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.
|Belay / Tie-In||One Loop|
|Waist Buckle Type||Quick Adjust|

Trad 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.
