What to Wear for Tough Mudder: Indestructible Gear for Mud Races

Squeezing into the UA EVO ColdGear Compression Leggings might take some maneuvering—they're ultra tight, like a second skin. But its compression technology keeps your muscles engaged the whole time for increased power and circulation. Dual-layer fabric keeps you warm in cold temperatures and wicks sweat away. Plus, an elastic waistband stretches with your core as you move so you won’t feel restricted. You’ll be thankful when you climb out of the ice-cold plunge and it takes your legs less time to recover than the guy wearing regular sweats next to you. ($50; underarmour.com)
