This is a very comfortable harness with a good set of features. The front gear loops do a good job at feeding quickdraws as you climb, and the rear ones feel comfortable with a backpack on and reduce the weight without reducing functionality too much. The split webbing seems to split into 2 sections in the leg loops and waistband, which distributes load a bit worse than the 3 section webbing you sometimes see, but allows for better breathability, and it contours over bony parts of my body better. It's not necessarily less comfortable than 3 section webbing, it's just a different feel. Compared to my black diamond harnesses, the buckle is smoother and there's a higher degree of waistband adjustability.

Great product! Lightweight and versatile. I use it 2-3 times a week for sport climbing or multipitch and thanks to the reinforced plastic ring it lasts a very long time!
Ideal sport climbing harness. Light, streamlined, comfortable and pretty bright orange.
Great harness. Perfect service from Valhalla Pure Outfitters. Thank you for your work !
The harness is light and comfortable. The front gear loop has good design to allow gear to slide forward as you take one away.
The only reason i didn't put 5 star i didn't try it on ice climbing for now but it's an excellent belt easy to fit good size very confortable !It's a good go to pretty close i feel of arcteryx harness
As the title says, this harness is EXTREMELY comfortable. All it took was two minutes of adjusting the leg loops and now when I fall it doesn’t scrape against my legs like the rental harnesses at my gym do. I’ve only used rentals and this one, but it also feels light.
I've been through a handful of harnesses now, and the sender is my favorite so far! It finds a happy medium between comfort and weight. For comparison, this harness is similar to the BD solution with a little more padding and a better feeling waist. The only thing this harness is missing is a coated rear gear loops. That said, coated gear loops are unnecessary for strictly sport climbing or even light trad climbing.
