Description

The next level - this ultra-light sport climbing harness boasts the latest technologies and a progressive design. The Alnasca Women uses a combination of split webbing design and Mammut® Frame technology (a lamination process that applies a TPU reinforcement to the mesh material in order to increase the lateral stability of the harness). This allows even distribution of pressure across the entire surface of the harness and unprecedented suspension and comfort. This is enhanced by the anatomical cut and extreme breathability of the harness.

  • Innovative split webbing technology
  • 2 stable gear loops and 2 ultra-lightweight gear loops
  • Aluminum Slide-Bloc buckle
  • Ultra-lightweight protector prevents wear on tie-in loops

Gear Loops

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.

Worth Considering

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.”

4 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.

Haul Loop

Haul Loop

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.

Outdoor Gear Lab Gear Review rating 4.5/5

For sport climbing and gym climbing where you don't need a ton of storage space on your gear loops or a ton of padding on your leg loops, the Alnasca is hard to beat. This is a well-designed lightweight model made for gym climbing. Its wide mesh waistband distributes weight well, without inhibiting movement. The leg loops are sleek enough to wear this harness around for hours without hardly noticing it's there. The belay loop is definitely sleek — almost to the point of worrying about its durability. The gear loops are also so small that it's hard to fit a lot of gear on them. These downsides are not a huge deal if you plan to mostly use this harness in the gym, though. For that reason, the Alnasca is our Top Pick for Gym Climbing.
