The Selkirk S2 Pro Pickleball highlight is a fast, firm, and exceptionally durable tournament-style outdoor ball that stands out for its unique warranty and visibility. It is a VERY fast ball. I recently played a few games in cold weather (starting at about 40% F) and found that you had to be careful with your ground strokes, especially if you are trying to hit underspin ground strokes. The ball will fly.
However, I got used to the ball after a few shots and was able to create it. I will say this about it – a Franklin X ball certainly would have cracked in the weather, but this ball showed no signs of wear.
The S2 features a 38-hole injection-molded design and is backed by pickleball’s first 1-year no-crack and no-out-of-round warranty. Virtually all other major pickleball brands (such as Franklin, Onix, and Dura) offer no warranty against cracking or softening, as lifespan depends heavily on temperature, court surfaces, and frequency of use.
Here is a comparison with other balls.
