This is my favourite strap:
Its on my GP Sea Hawk. I like it because its easily adjusted to any length by clipping these little prongs through the segments:
and its stretchy - but not like those old Spiedel or Fix-o-Flex straps.
It was made in Hong Kong. Very comfortable and looks good - to me anyway.
Anybody else got an old strap/band/bracelet that they'd like to share?
