Prism Duos straps give you sensitivity and fingertip control for the most advanced maneuvers. Extra finger loop lets you hold them traditionally in stronger winds or as finger straps for in light winds. Our clever foldover design means no plastic hardware to break or dig into your hands. Textured areas on pigtails let you keep a finger against the line for ultimate sensitivity without cutting into your finger. Color coded red and grey for easy reference. If you're serious about your flying, these are the best straps you can buy.
