Pushfins began with a simple design goal: to make high quality, performance surfboard fins that have a minimal impact on the environment. As raw materials exponentially raise the environmental impact of consumer products, we chose to source as much material as possible from post-consumer and industry waste channels. The primary materials in our fins are used/manufacture defect skateboard decks (seven plies of Rock Maple, one of the top five sustainably harvested hard woods in the world), fiberglass scraps from the surfboard shaping/glassing industry and Entropys bio-based resin. The only raw material that goes into our fins is a percentage of the resin and the stainless steel pins in our slider box fins, which means that over 90% of the material in each and every fin would have otherwise been headed for the landfill. SHRED MORE. WASTE LESS.
