{"product_id":"apeks-rk3-fins","title":"Apeks RK3 Fins","description":"\u003cp\u003eTrusted by military divers, special ops teams, coast guards, and public safety divers for decades — the Apeks RK3 is the benchmark rubber fin for serious underwater work. Built from ultra-rugged thermoplastic rubber with an oversized foot pocket designed to fit drysuit boots, the RK3 is as at home on a pebble beach as it is at 40 metres.\u003c\/p\u003e\u003cp\u003eWhether you're kitting up in thick gloves on a cold UK shore dive or gearing up for a technical twinset dive, the RK3's spring straps make donning and doffing effortless.
