This one comes from a reader who has been very happy with several Bison belts. Most of them are “infinite adjust”, like the USA-made GRIP6 belts, and they can be had in a staggering variety of widths, colors, and designs. Note that some of the belts use the Austria Alpine COBRA buckle, like my old (and no longer available new, but still working perfectly) Waterfield bag. Those buckles are NOT made in the USA, but they ARE made entirely in Austria.
Find them at Bison Designs.
