I start describing my body. I'm severely overweight, but carry all of my fat on my stomach and upper body. My body is shaped like a top, so it's hard for me to keep my pants on because I don't stretch in the hips and buttocks. To hold my pants I need a very tight belt. I've tried several of these tactical style belts as nylon generally doesn't stretch like a leather belt. However, the buckle mechanism can still be an issue when I'm sitting or crouching. I can get the belt to slip through the adjustable end of the buckle unless there is an additional mechanism to keep the belt from slipping. Some straps I've tried have a decent anti-slip mechanism, but when loosening the strap in a public restroom, it's too difficult to loosen the adjustment, re-tighten, and then tighten the strap again. The buckle mechanism on the adjustable side of the buckle prevents the strap from slipping off and is also great for adjusting the strap as needed. For a sling this cheap I am very impressed and would highly recommend it to anyone interested in a tactical sling.
