Compare to 1 pair of original Keepons Superstretch @$8
Hi, what's the difference between primestretch and superstretch?
Superstretch black and superstretch white has been around for a long time, and both have an excellent track record if you look at the online reviews.
The Primestretch black and Primestretch white were recently launched.
Well, from a manufacturer standpoint, both the Superstretch series and Primestretch series use the same material. Yes the exact same material blend. What do I mean by that? Well depending on the style and design, we use different material blends. An assortment of different silicones and other elastomers in varying amounts depending on the style. The reason for this is because each style has its own demands. The original series is very different from the superior series for example in terms of the chassis design. As a result we are constantly tweaking with chemical compound formulas (especially when we receive reports from customers that something went wrong with their Keepons).
So getting back on point, exactly what the Superstretch is made of, so is the Primestretch.
But with the Primestretch we extended its ability to stop slipping glasses on two fronts. One, we made the hook longer. Currently the Primestretch has the longest comfort hook out of all the styles. Second, we curved the hook more to more closely adhere to one's ears. Again, for greater stopping power.
Actually, the Primestretch was a design request from an eyeglass seller that specializes in sports opticals.
So in all fairness to both, the Primestretch is better than the Superstretch in terms of eyeglass slipping prevention performance. But that's why it's more expensive too. see less
