Red/white/blue strap.
I bought a couple of these in 2016 for my son, I kept one for myself. Worn every day, for work, I climb in it, swim in it several times a week. It goes in chlorinated pools, oceans and rivers. It has performed outstandingly. I have finally caused a very slight tear, whilst climbing. Going off the 'stich in time...' adage, I replaced it today. Nine years of exemplary service, so I bought two, to last me into my dotage. Ordered at 01:30 on Friday morning and it arrived at 10:00 Saturday. The service matches the product. Fantastic.
