For a while there we were talking about carrying the seatbelt nato (Omega nat0) but we had an issue with them, comfort. Not that we didn't like them, because they are really nice strap material. The issue is the design of nat0 uses two layers of nylon under the watch head.
If you have a material that is 1.5mm thick and up then you will have at least 3mm's of nylon under the watch head. So unless you have a super-thin watch, then that is an uncomfortable and weird-looking combo. In comparison, this material can be thicker than most zulu'z.
NOT all seatbelt nato material straps are the same quality. So you need to shop around for one with the best-sealed webbing.
