All The Gear You Need For Trail Running

Corded headphones will inevitably catch on bushes and brush, but even wireless buds aren't immune from snags; slack in the line connecting your earpieces is basically a magnet for low-hanging branches. The cable management system on Jaybird's svelte Freedom Wireless earbuds keeps the connecting wire wrapped closely and comfortably around your head's occipital bone, completely eliminating cord dangle. The buds, too, are pleasantly low-profile (the fiveish-hour battery lives in the in-line remote), so you won't have to worry about your beanie or jacket hood jostling them loose. $130

Even waterproof footwear takes on rocks, sand, and snow. To keep detritus out, protect your shoes' ankle openings with a good pair of gaiters. Outdoor Researcher designed its Ultra Trail Gaiters to be lighter than traditional, knee-high varieties, and more breathable, too—but they'll still keep debris and moisture from collecting in your kicks. $35-$40

Sometimes you eat the trail, and sometimes the trail eats you (or your running buddy). When it does, be prepared to take care of yourself. Adventure Medical's lightest first aid kit is perfect for single-day excursions, packing painkillers, bandages, antibiotic ointments, and moleskins into a waterproof pouch the size of a sandwich bag. The whole shebang weighs just 2.4 ounces, so there's no excuse for leaving it at home. $9

Trekking poles provide extra points of contact on steep, uneven terrain (something your back and ankles will thank you for on grueling mountain runs), and the Distance Carbon Zs do it at a best-in-class weight of just 10 ounces per pair. The shafts even separate into thirds with a push of a button, and fold like tent poles for efficient stowage. $160

Emergency blankets can shield you from chill winds while helping contain your body's radiated heat, reducing your risk of hypothermia if you find yourself injured, lost, or stranded in the cold. They're ridiculously light and inexpensive, to boot; a fancy one costs less than your lunch. $4

By now you've realized that a safe day on the trails requires some extra kit. So where do you stow it all? In Salomon's awkwardly named but impeccably designed hydration vest. It's got room for everything on this list plus three liters of water, delivering the carrying capacity of a daypack in a deceptively low-profile package. Soft, stretchy materials allow the vest and its contents to move with you with minimal bounce, while an array of well-placed pockets grant you easy access to your stuff while you huff and puff up the mountain. $175
