If you don't know already, Arc'teryx has been building and selling harnesses since 1989. They were originally called Rock Solid Manufacturing and harnesses were the first gear they made. After using all kinds of harnesses out there, I can tell you Arc'teryx's harnesses are on a totally different level! They are incredibly comfortable and lightweight, yet as strong as it gets. I've seen them made and R&D tested in person in Arc'teryx's Arc'One in New Westminster, BC, and was blown away by the amount of detail that goes into these harnesses. After wearing and seeing how they are made, I feel they are the best and most comfortable harnesses out there.
Arc'teryx has 2 models of women's harnesses currently, the FL-355 and the AR-385A. The main difference is that the AR-385A (AR for All Around) has adjustable leg loops and the FL-355 (FL for Fast and Light) has fixed stretchy leg loops and weighs even less. Both are great, it just depends on your preference for leg adjustability and the size of your legs.
Tipping the scale at only 12.5 oz, the FL harness is so light you don't even notice it is there. I like for my legs to feel snug in a harness, so I wasn't sure what I would think about the FL until I tried it. After wearing it, I realized I actually prefer the leg loops in the FL to the AR because the stretch leg loops move with you and feel secure yet extra comfortable. I wore it around all day climbing in Squamish and barely noticed it was there whether I was climbing, sitting, or hiking to the next climb. I never took it off until I was done for the day.
The ultralight, yet feature-rich FL is designed to handle any and all types of climbing. It has 4 gear loops, 4 ice clipper slots, auto-locking buckles, rear haul loop, SureFit elastic fixed leg loops, a quick hook that allows you to easily release the rear strap to go to the bathroom without taking the harness off. The whole harness is built with incredibly strong Warp-Strength Technology that provides an unprecedented even weight/pressure distribution across the whole harness structure, eliminating pressure points and providing next-level support.
The last thing you want to be thinking about when you're climbing is your harness, so if you're looking for an extremely comfortable, lightweight, and low-profile harness with every feature you need that's as strong as they get, I highly recommend you try the Arc'teryx FL or AR harness.
