I did another sweaty hour on the turbo yesterday, and popped the strap in a sock in the washing machine again, so nice and fresh today! That's 4 weeks of virtual 24/7 wear, and 8 hand washes and 2 machine washes, on either Voyager or Everest , my only 22mm watches. This is a lot more wear time than my nylon Natos get, as I have a good selection, so although I might wear a particular watch 24/7 in rotation for a couple of weeks it might have a fresh strap every day, or every other at the least. The fibres in the material seem to have settled down and the strap has a nice lightly worn in look, with a faint lightening in colour. I liked it so much that . . .
