Replacing my old faithful harness wasn't an easy decision but this one does the job well. This get's used for gym climbing more than outdoor now but I generally sport climb outside and I'm sure it'll do the job there as well. Just like my last mammut harness, I like the reinforced tie in point and it seems a comfortable harness overall, although I haven't used it too much yet. I feel very secure in this harness which is important for me since I don't climb as much as I used to so I'm less familiar with the feeling of being off the ground relying on my gear.

Great lightweight harness

It’s nice that it comes in an extra small. I do wish however that the small sizes had two gear loops. I don’t lead so it’s not that big of a deal. But when I follow it would be nice to organize gear. Helps my partner with better transitions.

My go to harness! super comfy harness and will stand by it! I've taken it on every climbing trip I have been on! Perfect for an experienced climber or someone just starting out; it works great for a great gym, sport, or trad harness! A little heavy for the alpine, but overall a great harness! 100% Recommend.

Comfortable

The thickness makes it kind of warm during the summer but at the same time provides a sense of security

Great for casual sport climbing

I got this as a secondary harness to my usual indoor sport harness, but I tend to reach for this one more. It's very comfy and lightweight but I always feel secure. I love the adjustability, specifically in the length of the leg loops. Favorite part is the shape and structure of the hard points, really easy to thread and tie into.

Not the same as pictured

I wanted to love this harness, because it really is comfortable, but the harness I received has only one gear loop on each side and not two as pictured. This was meant to be my outdoor harness, and I haven't noticed the loop thing because I was saving it for our trip. At the crag I realized I didn't have enough loops to clip on my gear. Even though we were climbing sport, using just one loop on each side was difficult. From now on it will be my gym harness, I guess. If you're looking for a gym harness, it's a great one, but for outdoors just stay away from this one.
