Ian Lauerwrote a review of Edelrid Zack Harness on August 10, 2017
Familiarity: I've used it several times
We bought this harness for our nephew who is 10 and getting into climbing. We bought him a S and it will have TONS of room to grow. We especially appreciate that the padding slides around waist belt, which allows it to be re-positioned for comfort and gear loop access as the waist changes in size. This is a massive problem I have with other harnesses, which cause gear loops to be offset if you use the same harness with bulky clothes or your waist is between sizes.
He noted to us that the comfort was awesome and had no complaints. I would definitely consider replacing my harness (a new Petzl Adjama) with this one.
