Arc'teryx FL-365 Review
Our Verdict
Our Analysis and Test Results
Despite the “Fast and Light” connotation that comes from the “FL” in its name, this harness is only 0.6 ounces lighter than the heaviest Arc'teryx choice, and the only noticeable difference is in the design of the leg loops. Instead of the clunky adjustable buckles, these leg loops have retractable elastic bands that stretch as much as needed to put the harness on but then cinch up snug against the leg once in place, an innovative design that we like. For this reason, we enjoy this harness more than the AR-395a and would recommend it first not only for its more refined design but also its slightly lower price tag.
Performance Comparison
Hanging Comfort
This harness uses Warp Strength Technology to disperse the weight of a climber throughout the entire waist and leg loops, rather than a design where there is a thin piece of webbing with padding over the top. It seems to work quite well, but the design also has far and away the fattest (bottom to top) waist belt of any that we have tested. Where it rests against the middle of the lower back, we like the fat design, but when hanging, we noticed that because it is so fat on the side of the body as well, it crushes in against our kidneys and lower ribs even more than most. We also have a problem with the leg loop design. Since it is made of such a thin piece of webbing, it tends to twist and gouge into our femoral region on the inside of the leg more than most. Don't get us wrong, no harness is all that comfy to hang in for protracted amounts of time, but compared to a lot of top-quality competition, this one is not very comfortable.
Standing Comfort and Mobility
The most significant advantage of the design is that it's very supple and mobile. We love how the harness moves with us as we walk about. That said, the very fat waist belt again presents a bit of a problem for us on warm days, when we find it to be quite sweaty. Also, when carrying a large rack, we feel it tends to slip down and chafe a bit. The freely moving gear loops and the very thin waist belt make this an excellent choice for wearing under a pack, and its mobility makes it a good choice for alpine and mountaineering use. However, due to its bulk, we find it to be far more noticeable to wear than most harnesses.
Features
This harness has all of the features you could conceive of a harness having, but we don't like the way that they perform quite as much as the features found on the highest rated Petzl models. It has four large, plastic-covered gear loops that are easy to clip and flexibly rest against the body, but we don't like how they taper downward to a point (we prefer a flat gear loop) because then all the biners crowd into each other and try to overlap, making it harder to unclip the one you need quickly. We also find that the sewn-on keepers for the webbing tail of the doubled-back waist buckle require the tail to be woven amongst the gear loops, and it gets in the way of our clipping once again. This harness does have the nice option of four ice clipper slots, and we think that the design of the elastic leg loops is superior to the bulk of the adjustable buckles found on the AR-395a, and so rated this one slightly higher for features.
Belaying Comfort
We think the FL-365 makes belaying more comfortable than the 395-a. We find that when holding a climbing friend while belaying, their weight is localized almost entirely on the leg loops, particularly as they wrap around the inside of the leg. These leg loops taper significantly in this region, and the added bulk means that we were more likely to need to adjust how it is hanging quite a bit, but also means that the sharp edges of the webbing don't gouge into our skin as badly as we would expect. Even still, we don't find extended belay duty in this harness to be all that pleasurable.
Versatility
This is a very versatile harness, usable for sport climbing, trad and long free routes, and even ice and alpine climbing. With its thin waist belt, we feel like it is even a good choice for mountaineering. However, it is heavier and bulkier, and not quite as comfortable as the harness we consider to be the most versatile, and its fairly snug fixed leg loops do not provide the same level of adjustability as models that have adjustable buckles.
Value
This harness retails for a little bit less than its comparable Arc'teryx cousin. Since we like the leg loop options on this harness better, we think it is a better buy considering it's also a bit cheaper. However, there are a handful of harnesses that we think perform quite a bit better and are way more affordable (like half as much!), so we wouldn't necessarily consider this to be the best value purchase.
Conclusion
The Arc'teryx FL-365 is designed to be “Fast and Light,” with fixed elastic leg loops to cut down on weight and bulk. It is one of the most versatile harnesses you can buy but comes at a pretty high price compared to the competition.
