The Fusion Comfort Technology creates an interior webbing that evenly distributes pressure: no more wriggling away from pressure points while hanging off the wall to figure out beta.

  • Single waist buckle and fixed leg loops for quick-and-secure fit
  • Fusion Comfort Technology breathes and moves with you
  • Four pressure-molded gear loops for quickdraws and other gear

Most comfortable harness out there

I’ve tried a ton of harnesses and this one really takes the cake for long days at the crag. Best sport harness out there. Big enough gear loops for draws and some gear even on long routes. Comfortable to belay in and even better to sit into on a rappel.

Super Comfortable!

I've been using the Black Diamond Men's Solution Harness in size large for my indoor climbing sessions at the gym, and it's been a game-changer. Transitioning between the bouldering wall and top roping has never been smoother. As someone who stands 5'11" and weighs 185 lbs, the large size fits me perfectly and provides exceptional comfort and support during lengthy climbs. The harness is incredibly easy to put on and take off, which is a significant advantage when moving quickly from one climb to another. Additionally, its sturdiness gives me the confidence needed for both safety and performance.

Extremely comfortable and effective

Saw some review online stating these are comfortable. After putting them on, I would have to agree! I do have athletic thighs and they fit snuggly without being uncomfortable. I feel confident while hanging for a break and lowering after finishing a send. Recommended my wife gets a set of her own. We're both happy (climbing) campers.

Comfortable and light

Bought for gym climbing. My last harness was close to 10 years old and I needed a refresh. I didn’t need leg buckles and these work great to not constrain me while stretching for a ledge. Padding is comfortable and overall this feels airy but well designed and safe.

Was having issues with pinching around the thighs with my last harness, with this harness I no longer have that pain!!

Solution harness

Super comfortable, light harness. I know it's mostly for sport climbing but a runner strength loop on the back would be good for shoes, trail line, etc. if you find yourself on a multi-pitch climb. The place where you tuck in the waist belt tail could be closer to the harness buckle, or the waist belt could be longer. I'm in the lower range of the waist size and it barely reaches to tuck in.

Very comfortable and light.

I've put it through the wringer
Size Bought:
5' 3"

I have owned this harness for 3 years now. It is my main harness and I use it for everything from top roping to lead climbing. It's super comfortable. The only issue is the position of the gear loops. The loops on the left side are not very well placed compared to the right side. Fortunately the loops are big enough to hold at least half a quick draws each.

Great Starter Harness

This is a great first harness. I am new to climbing and this is a great reasonably priced, comfortable option. I have no complaints.

Fits well; legs a bit loose but thicker pants make it work fine. 5’10” 125lb size small
