Black Diamond Flight Harness Reviews:


I have only used this harness a couple times because the ski season is still in. It only took one use, however, to make me a believer. This harness is awesome. It is comfortable. Sometimes you almost forget it is on. It's great. I really like the leg loops. You can adjust them to fit perfectly. The plastic is not weight bearing and therefore is not an issue. It just makes it more comfortable. The only thing that kind of bugs me is the lack of a gear loop in the back. I still haven't figured out where the best sport for my chalk bag is because of this. That was the only surprise. If anyone has any suggestions let me know.

Excellent minimalist harness. No frills, but still possesses the essentials. Great for sport climbing. Has the necessary padding for comfort, and fits a wide range per size.
One start deducted because the leg loops are small. I'm about at their maximum, but have plenty of room in the waste. I am big for a climber (6'3"/ 220#), so this might not be a problem for most.
There is a nice divider on the gear loops that helps one sort things out but keeps gear pretty close. This can work for some, and be a nightmare for others. I like not having to reach way back to get to the rear loops.

I'm 32' waist and 20.5' leg and Medium was perfect. Super lite and the speed adjust buckle works great for one hand tightening and no double-back needed. Don't worry about the trakFIT leg loop plastic adjustment buckle, its not load bearing and cannot see it breaking unless maybe by stepping on it. In 20 years of sport climbing this is by far the best harness I've had, its one of those great pieces of gear you want to buy two of so you have a backup of your favorite. I attached my chalk bag to the adjustable leg loop hardware in the back for no waist belt needed.

i love this harness!! so light yet so bomber. i can't even tell i have it on. no problems with it catching me on my redpoint attempts and no problems hanging out in it as i clean my sport routes. super comfy during both. i love the speed adjust feature. i was kinda sketched about the gear loops being so close to each other. i actually can't tell the difference with gear loops that are farther apart. not to mention the color is awesome. if u want a super lightweight and bomber sport harness, this is it.

I bought this harness to trad climb. There are two things about it that are attractive:
(1) It is minimal but supportive. Trad climbers carry more gear than sportos, what you don't want is even more bulk.
(2) The gear loops are square-shaped versus the traditional sagging loop in which the biners all bunch tight, comingle and clip to one another.
More than a few times I flew in the Flight, it doesn't bite when you hit the bight.

I love this harness so much its my first one and I have not gotten to use it yet but just by the way it feels on me I know its going to kick but out there. I was worried about the plastic parts of the harness but they feel very sturdy and they aren't even weight bering, Im sure they will be great.

Wow! Ive owned several harnesses...mostly BD, but I can say this is by far my favorite! At only 11oz it is as light as some of the other "top end" companies sell for over $100! You can barely feel this thing on! It lacks nothing you don't need and feels great doggin' on the wall! She is comfortable! Another AWESOME BD product!

Wasn't a huge fan of the fit of the flight harness. Felt a little loose and somewhat cumbersome in comparison to the minimalist harnesses I've owned previously. Ended up exchanging for the ozone and happy with my decision. For the money, however, the flight is probably one of the better harnesses on the market. Lightweight and versatile.

I love the fit of this harness. 32"waist, ordered medium. I have worn it from Shelf Road to Red River Gorge and it is quick drying. Only downside is there is no loop for a chalk bag. I would recommend this to any sport climber.

This harness is truly amazing. It's lightweight, comfortable, and adjustable. It's not a plush harness by any means but it packs a punch for being a minimalist harness. Black Diamond knocks it out of the park again with this one!
