What’s on this list
Speedo’s Endurance+ flyback runs about $42 and Arena’s Icons Super Fly Back runs about $57, both in a chlorine-resistant polyester weave. The flyback’s thin, crossed straps free up the shoulders for stroke work, which is why it shows up on club and fitness rosters more than any other cut.
