Zephir Altitude 2015



My vote: None ( 3 avg )


Extremely lightweight alpine harness with minimal packing volume for high-altitude tours and ski tours. The Split Webbing technology (patent application pending) in the hip belt, together with the very strong Dyneema® webbing in the leg loop construction, ensure great comfort and allow a modern design with large ventilation openings for high breathability. Gear loops and the drop seat buckle are positioned to allow the Zephir Altitude to be worn easily together with a backpack with a hip belt.

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.”

2 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.

Powder Magazine Gear Review no rating given just a review

Weighing 215 grams, the Zephir is lightweight, and it features a wide waist belt and leg straps so it is comfortable when skinning, skiing, and especially when rappelling. The gear loops have a thin plastic outer lining, which keeps your gear in place rather than swinging between your legs when you are climbing to reach the top of the couloir. The wide Dyneema, a durable webbing material, dries out incredibly fast—even in the Northwest–and stuffs easily in your pack because it is so low volume. The harness also has sewn loops for two ice clips to be added to the harness in case you need to carry additional gear; perfect for climbing up the North Ridge of Mount Baker, and then skiing back to your car.
