Interesting, are they soft or firm? Not really sure would have to feel one but looks cool.
I've been using them for over a year and they're still going strong. They have a breaking point of 80lbs.
I'm sure they'd be fine for my midget digits Are they saving that much weight over 550?
I asked several women that over the years!
They may also be easier to use in production as you wouldn't need to melt the ends and they look easy to thread onto the zipper. Also less chance an employee would burn themselves with the hot cutter I assume you use to cut the 550.
Not really, but you could get some and then sell them on the classifieds.
Along with everything else. I got boat and plane charters to pay for
