Slightly OT, I have a wristband made like that, with a clip at either end.
I got it cheap, from China, via Amazon (using up the last few pounds on a voucher I got for my birthday)
I view it as useful to have in case of emergency and it only weighs a few grams. This is all part of my weigh-reduction plan for the trip next year (including ditching the full sized leatherman in favour of a tiny little one)
