Increase your power to weight ratio with Hollis Gear's new F2 Fins. If you are a traveling diver, looking to reduce weight or just favor a lightweight fin, look no further. The patented F2 is designed to add blade surface on both the down stroke and up stroke to increase your efficiency with any type of kick. The F2 is injection molded using high grade, heavy-duty monoprene construction and uses a shorter blade design which packs easy and improves agility in tight areas. The F-2 Fin has a vented blade design that reduces stress while accelerating water over the blade. The generous foot pocket will accommodate various foot wear depending on the water temperature. The F-2 Open Heel Fin is available with adjustable stainless-steel spring straps that have angled strap mounts for comfort and a better transition of power. The fin is equipped with multiple strap mounting positions for a fine tune fit. The spring strap assemblies have an easy grip heel tab for quick and efficient donning and doffing. The spring straps are also depth compensating so no need for adjustments while on a dive. Fin is black in color, and comes in multiple sizes.
