How to use, warnings, inspection and retirement with instructional pictures.
A great all around harness, the Sonic features a wide, flared waist for excellent comfort and superb fit. Improved with 500 D Nylon Cordura fabric at high wear areas, it has a cool Grey/Copper/Black color scheme. Great for all types of free climbing, the Sonic is equally at home doing laps on sport routes as it is at hanging belays on multi-pitch trad.
* Flared layered waist is 4” wide in back for support
* Leg Loops are 3” wide in back for comfort
* Rear webbing

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|
|Leg 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.

When you’re pumping out 10 feet above your last fiddled-in nut, the last thing you want to sweat about is how much it might hurt to take a fall in your older-than-dirt harness. Don the completely redesigned Sonic and you’ll be as relaxed as Willie Nelson getting recreational in Colorado. Testers loved it for long routes like Yellow Spur (5.10a) and The Naked Edge (5.11a) in Eldorado Canyon, Colorado, where tight belays forced semi-hanging stances. “I could sit in this harness for long periods without experiencing pain or numbness,”
A pictoral representation of UIAA-105 and EN-12277 standards for harnesses.
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.
