Winglets are small protrusions on the upper surface of the paraglider near the wingtips that, generally speaking, stabilize straight-line flight. At UP, they’re only used when they fit meaningfully into the overall construction - as is the case, for example, with our 2-liners like TORRE. For wing models which are particularly agile, the winglets help to stabilize the glider to fly straight when needed. That can be useful for example when exiting a spiral dive or during transition from one thermal to another.
