While the Triton was one of four vented fins in our test, a closer look quickly shows that it’s really more a mix of classic and contemporary design. It’s almost 6 inches longer than any of the other vented designs and is made of a thermoplastic that’s quite light, making it nearly a pound per fin lighter than the heaviest model. The material has flex but with a decent snap (the Triton was one of the few fins that wasn’t rapped by any testers as too flexible or too stiff). The Triton finished our test with one of the top combined scores, tied the highest scores for stability and acceleration, was rated best for surface swimming (thanks to its light weight), and multiple divers put it on their lists of top-three fins of the test.
