Yes, it's a belt, and yes, it holds my pants up. But I love this belt. I had been alternating back and forth between the Patagonia Tech Web belt and your standard brown/black leather belt for a couple of years. On a whim, I decided to throw down the $25 for this one, mostly just because I wanted a fresh color option. However, it's become the only belt I use.
At first I was concerned at its minimal 1.25 inch width, thinking it would dig in (I'm an adventurous sort but I could stand to lose a couple pounds, I admit) or somehow be less effective than the wider Patagonia Tech Web belt. In fact, it digs in considerably less! I didn't realize how uncomfortable I had been until I got my new belt in the mail and wore it for a few days. In addition to the increase in comfort, I find it considerably easier to put on because of how slender and lightweight it is. It just glides through my belt loops. The buckle, though just a simple, small chunk of anodized steel, works flawlessly. I almost never have to make any adjustments throughout my day. I've got about a 36 waist and it's just the right length. It might be fine for a 38. From the tip of the belt to the tip of the buckle it's 45 inches long.
This may seem like an absurdly long review for a simple belt, and it is, but that's just a sign of how much I like it. In fact, I think I'll buy another one in a different color right now!
