I was looking for a belt that was more adjustable than a regular old belt that uses holes to adjust the length (I'll admit my my weight and waist size change year-round, and I couldn't afford to drill new holes in my belt). This belt does the job perfectly! It cannot be adjusted indefinitely, but it uses a locking mechanism with eyelets built into the back of the strap that allow it to be adjusted by a quarter of an inch or less. I like this belt very much and can only recommend it. I have one in black leather with a simple metal buckle that I wear to work, but there are many options for belt material and buckle style to suit everyone's taste.
