So last year I've been cooking at home and I've gone from a 5ft 8210 athletic build to a softer version of myself with an over 50 bonus Pounds up... turns out My cooking skills are pretty solid, in contrast to my new waistline. So, with this new physique, I realized that not all harnesses are comfortable to sit on. The elasticity of this strap allows me to adjust it so that it performs the same function as the straps when standing while not being too tight when seated. The buckle isn't perfect, but it's SIGNIFICANTLY better than a more traditional buckle, and the plastic doesn't cause any reaction or wear on my stomach like some metal buckles. "It's All Lava" just as serious and went outside and withstood the outdoor crowd a little more, but since I did, I'm sorry I didn't find that belt sooner. Not perfect but I can't think of anything that could be which is why I got 5 stars for the best belt I've found. I recommend it. I'm sitting up straight and the belt doesn't hurt.
