Over the last year, I lost a lot of weight. This was recommended by a customer of mine. I’ve cut about six inches off as my waistline decreased. Also, I drive to service equipment daily. So, hours behind the wheel. Lots of walking, getting up and down. Simply, I can loosen and tighten as needed in a second. Loosen while driving, tighten when pushing equipment with a tool pouch attached. The buckle is heavier than expected, but after the initial unboxing, I’ve never thought about it again. I’ll be getting another in another color/style for other outfits.
