DSP-JD: this is a new design that has a new clever but so simple solution to the problem of sleeve covers slipping down your arm. We have made one end with a stronger rubber band that holds it in place. Handmade not machine made so they don't rip when you put them on.

DSP-SPP: these are for use in rooms where the temperature is more of a standard room temperature 18 degrees and above. This allows the sleeve cover to still be water resistant but at the same time allowing it to breath. This stops that uncomfortable feeling of moisture build up under the sleeve cover.
