Arc’teryx Satoro AR Zip Neck LS Shirt ($139)
This buttery merino base layer uses elastane for a slim fit wear after wear. The Satoro has a zippered chest pocket that’s big enough for a credit card and a key, but it’s low profile enough to layer well.
Patagonia Nano Air Hoodie ($299)
With exceptionally permeable face fabric and 60-gram synthetic fill, the Nano Air breathes when you’re working hard and insulates when temperatures drop. The soft outer remained stink-free after 16 consecutive days of wear. Bonus: Patagonia’s hoodie is now partially made from recycled material.
Under Armour True Wireless Flash Earphones ($169)
Engineered by revered audio brand JBL, these compact Bluetooth earphones stay put during exercise. They run for five hours on a charge (and 15 more via the included charging case) and can boost voices and ambient sounds, letting you hear friends and passing cars.
Nike Epic React Flyknit 2 Running Shoes ($150)
The latest version offers a molded heel for stability while retaining the cushion and bounce of its predecessor. Turnover feels snappy—ideal for speedy short and middle-distance runs—and the stretchy knit upper affords socklike comfort without sacrificing ankle support.
Clif Bar Builders Protein Bars ($9 for six)
When you need a recovery snack in a pinch, we recommend the Builders bar, which is free of high-fructose corn syrup and trans fats. The mint-chocolate flavor goes down easy and has 20 grams of protein to help prepare your muscles for the next mission.
The North Face Flight Night Tights ($99)
With a fleecy lining, these polyester tights saved our legs during blustery winter trail runs. They’re thick enough to insulate without obstructing your stride when temps drop below freezing.
Saxx Kinetic Boxers ($37)
Like all Saxx boxers, the Kinetic features the patented BallPark pouch to keep your business in place, but the fit here is a little more snug. No more mid-run wedgies, so you can focus on what really matters: your workout.
Nathan Peak Waist Pak with Insulated SpeedDraw Flask ($55)
We dig the Peak for its body-hugging fit at the hips. A zip pocket houses extra fuel.
Fits Performance Trail Quarter Socks ($19)
After months of testing, we continue to reach for these socks. The merino-nylon-poly-Lycra blend feels cushy but not too heavy or warm, and the cuff, which sits between crew and quarter height, insulates that cold spot between your tights and shoes.
