Mosquito Men
Description
This is the lightest harness Wild Country has ever made. Engineered specifically for sport climbing, its precise fit delivers super-lightweight comfort, agility and freedom of movement. The advanced, lightweight, laminated waistbelt construction features internal load-bearing webbing that distributes the load evenly across the entire harness structure, combined with super-light mesh padding and a robust, fast-drying and abrasion-resistant covering with seamless edges that is soft and smooth next to the skin. This harness is built specifically with freedom of movement in mind. Its sleek, stripped-down construction adapts to your body for full, unhindered, flexibility as you climb. An important stand-out safety feature is the wear indicator on the reinforced lower tie-in point – a feature used by Wild Country since the 1990s. To clearly indicate when it is time to retire the harness, it has red threads that only become visible after excessive wear and abrasion.
The Mosquito is equipped with lightweight gear loops: two rigid front loops, two softer back loops, to prevent pressure points when climbing with a pack. All gear loops are designed specifically to hold your gear and draws away from the harness for smoother retrieval. There is also a decent-sized rear haul loop that also doubles as a chalk bag attachment point.
With a self-locking, aluminium slide block buckle on the waistbelt to ensure a secure and comfortable fit plus lightweight, supportive leg loops with elasticated risers. The Mosquito packs down small and comes in a stylish, two-tone black and white design with a classic Wild Country tangerine orange buckle.

The Mosquito weighs in at a scant 240 grams which puts it amongst the lightest fully functional sport climbing harnesses on the market. After several months of use all of the materials are holding up well without any creasing in the legs loops. This has become my go-to harness for sport climbing.

The Wild County Mosquito Harness enters the realm of ultra-light packable harnesses at a very competitive price point. Half the price of a Petzl Sitta Harness (my gold standard for a year round harnesses), $60 cheaper than the Black Diamond AirNet Harness, and able to hold its own in most comparisons. This harness is marketed for sport climbing, but I tested it for both sport and traditional climbing about 50/50 and I think it’s a great traditional harness as well as suited for sport climbing. This harness is not equipped for ice climbing just like the Black Diamond AirNet Harness (no slots for ice clippers), so if you’re looking for a year round harness that can handle ice climbing as well I’d point you back to the Petzl Sitta Harness. If you are looking for an affordable ultralight breathable sport and traditional climbing harness that packs up small and performs great, this would be a solid model to try!

The Mosquito is an excellent and super lightweight harness ideal for higher end sport climbing. It has all the features you need - including ample gear loops - making it a top performer in its class. The only caveat is that it's not comfortable for sitting in for long periods of time, so it's best worn for climbing rather than long belays.
General information and pictorial instruction for using correctly.
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.
