Long summer days call for big runs and rides. Staying hydrated on your enduro-epic is key for both performance and recovery. Here, five endurance athletes share their preferred hydration systems for when they鈥檙e on the go and need to keep moving.
UltrAspire Iso Versa

Ian Sharman, Professional Runner and Coach
Ian Sharman is not a fan of race vests. 鈥淚 use handhelds on all my long runs, ultras, or even shorter training runs in the summer heat. It gives me bonus exercise for my arms and shoulders on a run,鈥 he says. This is shaped for easy holding and comes with a mesh sleeve鈥攁lmost like a fingerless glove鈥攖hat secures it in your hand without requiring a firm grip. The design leaves your fingers free to dig through pockets or adjust your hat on the fly.
CamelBak Chase

Rebecca Rusch, Professional Mountain Biker and 国产吃瓜黑料 Racer
鈥淚 love this for cycling for so many reasons,鈥 says Rebecca Rusch. The low-profile hydration system has a 50-ounce聽liquid capacity and pockets that offer easy access to snacks and gear. 鈥淚t allows me to have my food, phone, and other essentials within reach, so there鈥檚 no need to stop and take off the vest,鈥 Rusch says. The close-fitting cut minimizes bouncing and chafing, and the pack sits high on the back, allowing access to back pockets鈥攁nd snacks.
Osprey Duro Series

Payson McElveen, Professional Mountain Biker
Payson McElveen loves his聽聽pack聽from Osprey (he鈥檚 a brand ambassador), because the聽streamlined design聽is聽ideal for the multisport endurance athlete. The pack is burly enough for long excursions yet sleek enough to wear during races. 鈥淚t鈥檚 actually a running-pack series, but they work聽really well for riding, too,鈥 McElveen says. 鈥淚t fits nice and snug and high on the back. I actually usually forget I even have it on.鈥 Though it looks and feels lightweight, the Duro pack provides ample space for food, a layer, and a 1.5-liter bladder.
Platypus Soft Bottle

Steph Davis, Climber and BASE Jumper
A Moab local, Steph Davis depends on easy hydration to fuel her desert adventures. 鈥淚 love the , because they鈥檙e light and so small when empty.鈥 They鈥檙e also cheap and convenient鈥擠avis keeps a couple cooling in her fridge at all times.
Nathan VaporHowe

Devon Yanko, Ultrarunner
Devon Yanko digs this inspired and developed by fellow Nathan athlete and ultramarathoner Stephanie Howe. 鈥淚 honestly find carrying things my least favorite part of ultrarunning, so a lightweight vest like the VaporHowe works perfectly,鈥 Yanko says. The 12-liter vest has a slim fit inspired by technical apparel and was built with plenty of stretch to ensure it stays put. The pack includes a 1.8-liter bladder with an inverted design to minimize air bubbles that cause sloshing on long mountain jaunts.
