Get the Black Diamond Momentum AL Climbing Harness for versatile performance that doesn't break the bank.

The Black Diamond Momentum AL Climbing Harness provides all-around versatility for both summer and winter use without draining all the new-rope money out of your checking account. Despite the modest price, the Momentum AL Harness includes a bullhorn-shaped, well-padded waist-belt to ensure comfort even at precarious hanging belays. Four molded gear loops hold a large rack of cams or draws. Black Diamond added adjustable leg loops, so this harness fits well even if you have to add a few layers for a cold-weather send.

Great for beginners like myself

I started climbing about 3 years ago with some of my friends. We go indoor climbing quite a bit, and I got tired of using those crappy rental harnesses that they give you because they have zero padding and are uncomfortable on your boys.
So that's when I decide to get my own harness to use. My only criteria were that it had to be fairly inexpensive, yet have some of the things that you would find on a nicer harness. I have to say that the Momentum has done just that. It is really comfortable, reasonably priced, and it has a lot of nice features.
As far as durability goes, I have had this thing for almost 3 years now and it has held up really nicely.
Basically, this harness is perfect for people who are just getting into climbing and want a good, entry level harness.

Beginner's Take

I've only done indoor climbing for just over a week now but this harness fits me fine and is as comfortable as I could ask for. Perfect value for indoor stuff although I really can't say how it would handle the outdoors.

Couldn't ask for anything else for a harness at this price. Easy to get in/out of and wellpositioned stiff gearloops. Use it in the gym og on the artficial wall outside.

I have a fluctuating waist size - b/n 38" and 39". Yeah, I know. Would the 2XL fit me or should I go with the XL instead?

Recommend :
- Summer : XL

Everyone remembers their first

Seems to be a popular first harness for a lot of people for some great reasons. Cheap, adjustable, and comfy. I have since upgraded and realized that this harness did pinch the manparts a bit more during a hard fall than some other harnesses out there, but it could have been worse. Once it's been readjusted after a hard fall, it's still comfy enough to hang in for a long time. I still grab this one as a gym harness as it doesn't cause any issues for me while toproping. For the cost of this harness, it's a good deal and is especially a great choice for a new climber that wants a comfy harness without dropping a larger budget.

Awesome value

Like the other reviewers, the Momentum AL by BD is a fantastic and affordable harness for your rock/ice climbing needs. I've found that its pretty darn durable and very light (didn't notice it while climbing some of the Flat Irons in Boulder). I've had little problems putting it on or off and it can become rather compact for a trek, if you so choose. Honestly, I've trusted the value I get from Black Diamond for years now and bottom line: this harness didn't disappoint me.

Great mid-line harness

This is not my primary harness, but it is comfortable, light, and perfect extra for lending out.

I'm about a 30" waist, should I get a small?

Responded on


A small will probably work just fine, but pay attention to your thigh size as well. I also have a 30" waist, but my thighs barely fit into my small-sized harness. I would also suggest buying a medium if you are unsure.

Happy trails!

Black Diamond (BD) Momentum AL Harness

The Black Diamond Momentum AL Harness is best of both worlds, comfortable & affordable. The Momentum AL Harness works great from desert sport climbing with shorts & a t-shirt to alpine climbing with a parka. I recommend this to friends getting into climbing.

I've never been disappointed with any Black Diamond product I've used. The momentum harness is perfect for the casual climber or someone just getting into the sport. It's easy to use, comfortable and sturdy. High quality, good price. I recommend it for anyone.

Awesome Harness

This is a wicked awesome harness! The buckles are easily adjustable, and the waist/leg straps are ridiculously comfortable. I do a lot of hanging while maintaining our tree course, and I have yet to be uncomfortable in this harness.
The sizing chart, in my opinion is a bit off, I wear a 36 pant and originally bought the XXL harness. It was way too big. So I bought the XL and that fits great.
Would most definitely recommend this harness.

great "everything" harness

So I've grown out of my 20 year old Petzl harness, and this looked like a nice option. I love the adjustable leg loops, partly because it's easy to put the harness on over any clothing you might be wearing, but mostly because I don't feel like I'm trying to wiggle into really tight underpants like it was with my fixed leg loops. Also, this has a real haul loop on the back, 4 gear loops, and it's the perfect balance between comfort, light weight, and affordability.

It Won't Stop Your Momentum

This is the first harness I've owned and for the price you can't go wrong. Easy adjustments will confirm a snug fit in any weather. I haven't felt any pinching or binding at any time while wearing it. The only thing is that it doesn't pack down tightly but that's not that big of an issue.

Excellent First Harness

I've had this for about a year and a half now and find it perfect as a general use beater harness. It's very comfortable thanks to the abundant padding. I've never had any painful experiences taking falls in it. So far it's shown very little wear and tear. The leg and waist buckles are easy enough to operate, nothing special though.

For the amazing price it's a great value. It works well for all types of climbing so I highly recommend it for any beginner. You won't be disappointed.

Only gripe is that it is bulky and does not pack down small. You never forget you are wearing it even after a full day and it takes up a lot of pack space, but this is a tradeoff for the durable and comfortable construction.

There are several "improvements" that could be made but each of those would make it more of a specialized harness and ruin it's all-around quality. The harness is heavy, but lightening it would sacrifice comfort and make it more applicable to sport or mountaineering. Making it more easily adjustable or fancier technologies would just make it more expensive.

Definitely great as it is for the starting climber.

For 50 bucks, this is one of the best buys you can find. Compared to others around its price range, it is lighter and more comfortable. Definitely recommend as a first harness. This thing works for almost any type of climbing, plus its taken all my abuse.

All Day Comfort

Excellent harness offering all day comfort for everything from trad to TR to mixed climbing. Adjustments can be difficult in cooler weather when your fingers are a bit less nimble, but that can be easily cured by simply warming up your hands. Great fit as well - go with the sizing chart and you'll be happy!

Love it

• Comfortable
• Affordable
• Great gear loops
• Durable
• Really safe

• It's a little difficult to take on and off, (compared to other harnesses I've used) but that just means it's gonna stay on when you want it to.

As far as bang for your buck goes, you really can't beat this thing. It's a great harness, and if you're looking to buy your first harness, definitely pick one of these up.

Best all-around harness

Got this for 50$ at REI, and I recommend it to all new climbers. Compared to other harnesses, very inexpensive, but also very bomber. Very comfortable in just about any use including hanging belays, well made gear loops (the design makes clipping gear into it very easy), and all the components you would expect from a good harness. As subjective as this is, it just FEELS burly, but isn't bulky either. You cannot beat this harness for the price.

Bottom line: unsure of what harness to buy? pick this one.
