A compact and supremely comfortable harness that built for versatile ascents – rock, ice, alpine, mixed and more

The FL-365 Men's harness from Arc’teryx is the compact, comfortable, streamlined men’s fixed leg harness versatile enough for sport, trad, alpine, mixed and ice climbing. The FL-365 can cover all of these disciplines with enough racking options to take on nearly any route. Created for lightweight versatility and performance comfort, the FL-365 utilises Arc’teryx’s proprietary Warp Strength technology for exceptional weight distribution with dependable strength. 

Improved tie-in points with orange wear indicators help elevate safety, and the careful patterning and burly double weave stretch material for the rest of the harness highlight the Arc’teryx commitment to the relentless pursuit or quality and performance.

The best bits...

  • Self-locking buckle for speedy adjustment and superior safety
  • Wear safety markers on belay loop and tie-in points indicate when it’s time to replace your harness
  • Four ice clipper slots for racking screws and other winter protection
  • WST (Warp Strength Technology) load is evenly supported across entire harness structure – an Arc’teryx innovation that cradles the body and the load is universally dispersed from edge to edge. This construction method provides a high degree of support and this new generation of harnesses are more comfortable over time and usage than ever before.
  • Stainless steel quick hook on the rear leg elastic permits using the bathroom without taking off your harness – trust us, it’s useful
  • Sure-fit elasticised fixed leg loops enable a precision fit with varying layers
  • Rear haul loop
  • Stretchy mesh storage bag
  • Four polyurethane gear loops
  • Burly double Weave four-way stretch fabric
  • 7075 T6 aluminium anodised buckle
  • Ultra-Compact design – like all things Arc’teryx the FL-365 combines minimalism and functionality in the smallest package possible
