Bring out your inner Zach.

When Nathan named the VaporZach 2.5L Hydration Vest after a champion runner, they did so with your potential in mind. The VaporZach helps you stay hydrated and prepared for race day, and for all of the arguably more important training days that get you there. The two ExoShot soft flasks have extended tubes that make it easy to get a sip of water or electrolyte mix with just a turn of your head, so you can power through even the most grueling workouts. Small pockets stash nutritional supplements or your exercise tracker (which may double as a phone when you're not running), and larger pockets in the back let you shed a layer without rocking the old-school, tied-around-the-waist look.

  • Hydration pack for training and racing
  • Two ExoShot flasks included for convenience
  • Extended straws for easy sipping
  • Double chest straps reduce bouncing
  • Small pockets keep supplements and gadgets accessible
  • Larger pockets hold layers and supplies
