A What materials are used in Slammer fenders, and how durable are they in harsh marine environments? Category: Product FAQs Slammer fenders feature a premium closed-cell foam inner core that’s highly impact-resistant and absorbs minimal water, ensuring it maintains its shape even under repeated pounding from waves and boat impacts. The outer cover is made from 30oz PVC-coated, marine-grade fabric—the same UV- and abrasion-resistant material used in top-tier marine inflatables—protecting against saltwater corrosion, fading, and cracking. This construction makes them impervious to extreme weather, saltwater exposure, and daily marine punishment, far outlasting traditional inflatable fenders that degrade in 1-2 seasons.
