Ultimate Direction Signature Series Adventure Vesta 4.0 Pack ($160)
At 12.4 liters, the Adventure Vesta holds enough for your most high-caliber days, with ten pockets sized for everything from gels to jackets, plus a hydration-bladder sleeve and load-securing straps.
Coros Apex Watch ($350)
Ultra in everything but size, the slim Apex lasts 100 hours with GPS (30 days without), has wrist-based heart-rate tracking, and designs workouts based on lactate threshold. Navigate with just two buttons.
Rowkin Ascent Charge Earphones ($120 and up)
Perfect for those who need some distraction on a multi-hour run, these wireless earphones stay put and pack 50 hours on a charge. An app locates misplaced buds via Bluetooth.
Norrøna Wool Singlet ($79)
Norrøna’s simple merino-polyamide tank regulates your core against high-elevation temperature drops even when wet, but the relaxed fit and light fabric let in the breeze when the mercury rises.
Survive Outdoors Longer Emergency Blanket ($5)
Carry this three-ounce, vacuum-metalized polyethylene lifesaver on high-mountain runs. Waterproof, windproof, and heat reflective, it’s inexpensive insurance against the unexpected.
Fits Performance Trail Quarter Socks ($19)
Cut just above the ankle, these merino-nylon-polyester socks protect against roots, rocks, and grabby flora. They’re thicker in high-abrasion areas to stay hole-free over the long haul.
Tracksmith Session Shorts ($62)
Cut from a silky blend of nylon, elastane, polyester, and spandex, the Sessions stretch with every stride. The 2.5-inch inseam strikes a perfect balance between mobility and coverage, and the adjustable, covered-elastic waistband stays put and resists chafing.
Salomon Ultra Pro Running Shoes ($150)
The Ultra Pro’s midsole is cushy without the bulk, and the TPU insert won’t pack out over 100 miles. Four-millimeter lugs grip slop and ride smoothly over rocks.
Brooks FastForward Free Sports Bra ($32)
Don’t let the dainty looks fool you: this bra’s light poly-spandex mix dries fast, and the thin crossback straps are surprisingly supportive. Bonus: a stylish cutout above the bottom band liberates under-boob sweat.
