Lost cover to your favourite fin? Don't leave it unprotected. Heavyweight polyester fabrics on the outside, comfy soft neoprene on the inside secures your valuables. A thin ribbon of clear silicone gives a snug fit around the fin - so won't fall off easily. Our robust covers match most slalom- and freerace fins, however if you have a normal straight / rectangular tip fin, you might want to choose one size larger than for the original Hammer SL. The covers have a nice transparent pocket, in case you want to add a note or specification. Comes in three generous length intervals.
