Arc’teryx FL-365 Review

Ever since Arc’teryx first released their “Warp Strength Technology” line of harnesses several years back, I’ve been a fan. Light, sleek, super packable, and quite comfortable, these harnesses have been the ones I’ve opted to wear more than any other.

One problem, however, that past models had was the tendency for the leg loops get “crinkled” up. The leg loops would fold/bunch up right under your butt, which would be uncomfortable and less supportive.


The new Arc’teryx FL-365 (FL = “fast and light”) has completely solved that one little nagging problem. With four gear loops, great durability, a compact lightweight form factor that packs down really well, and supreme comfort, the FL-365 might just be the perfect all-around harness. Whether you’re doing trad, sport or alpine climbing, I have a hard time coming up with a good reason as to why you wouldn’t want to wear this rig.

Price might be the one hang-up for most folks, understandably so. At $145, the FL-365 is double what many other, perfectly fine harnesses cost. My last Arc’teryx harness lasted 3 years before wearing out through the tie-in point. The FL-365 appears much sturdier and, while I’ve only been using it for 6 months, it still looks brand new. I expect this rig to last me years.

The major difference in the 2015 line of Arc’teryx harnesses and previous models is that the swami belt and leg loops feel much sturdier and more supportive. This is the best iteration and application of Warp Strength Technology to date.

The harness is about 5 grams heavier than previous models, but for what you gain—increased support and comfort—the extra weight is totally justified.

The FL-365, and its sibling the AR-395a, which is the same harness except with leg loops, has four gear loops, a beefier tie-in point, an easy-to-clip haul loop, and a new drop-seat hook.

These harnesses also come in women’s versions, the FL-355 and the AR-385a.
