I've been using Maratac Zulu straps for about nine years. They are cheap, durable, attractive and washable. And breathable.
Maratec makes the best and although only 1.2 mm in thickness, the toughest. Because of the thinness, as a NATO strap…this results in the watch wearing closer to the wrist. I have tried many brands/ varieties…IMO these truly are the very best. Countycomm service is superb.
Bought this strap for my Hamilton Khaki field watch. The brown colored strap is really more of a dark khaki which compliments the colors of the watch nicely. A few things I really dig about the strap: plenty of length, very close hole spacing with lots of holes (fit is dialed in), and the engraved branding on the buckle is a nice touch. My only minor complaint is that one of the metal rings sort of loosely flops around. It's the one the strap passes through right after it goes through the watch and links the two pieces of the strap back together. Ideally, it would just hug the strap a little more snug here. Otherwise, a great strap and I'm enjoying it.
A great product and compliments the old Radium of the watch face just like I wanted.
