What Our Gearhead(R) Experts Are Saying: "I like these bottoms for days when I want a playful fit that still feels comfortable in the water. The tie sides make it easy to dial in the fit, and the stretch fabric stays put while swimming. They're a great option for mixing and matching with different tops."
