These straps are perfect for my cargo pants. Nylon buckle, sure. The woven fabric looks good and is strong enough to last for years. FYI: I measure as 1 3/4" for the buckle, 1 1/2" for the webbing, and it fits perfectly through 2" pant loops. The buckle, as I said, is reliable, very easy to tighten and remove. This is a great product.
