OAKLEY Eyewear Leash LARGE SIZE nero - cinturino, fermo, cordino

For me these are the perfect strap for sunglasses (or my everyday Ray-Ban Wayfarer Metas)
I probably like them for the same reason that others hate them; in that the leash is basically a thin coated wire / cable with rubber ends to slide on the arms of your glasses.(The large fits the Wayfarers so they're plenty big enough for most glasses too)
I really like this design as I find it unobtrusive and comfortable and, with its slightly shorter length: to the top of my shoulder blades, means I actually catch it on clothing less.
Also the design itself is smart and modern. I much prefer its look over the Cottons or neoprenes that are mostly used by rivals. That's a great look on the beach but not so much in an office or mall where these just blend in nicely.
All in all, I'd recommend them 100% and, indeed have purchased several pairs from S2as.com as I've been so pleased with both the leash and their service....and prices!

Great strap for retaining your prized sunnies, but very stiff (like wire), so does catch on hoods and collars, and you can often feel it ribbing on your neck. Does the job, but could be better.
