XTERRA Lava Pants
The draw: Superhuman speed
We’ll say it straight up: Wearing these neoprene pants is cheating. They’re like jammers on steroids, giving your hips the lift of a pull buoy, but letting your legs kick like heck. We put them on at the end of a 2,000-yard workout and busted out a 100 about 15 seconds faster than usual. But they’re not just for showing up your fellow Masters swimmers; forgetting about your hips for a while will let you focus on stroke technique. A low front waist makes flip-turns comfy. Note: Wear these over your swimsuit or you might have some awkward chafing issues.
