Grab it and go: the Cloud Walker hydration pack is a simple, classic daypack perfect for hikes and less technical adventures. When you’re staying close to home, just remove the reservoir for extra storage capacity. Hitting the trail? Throw it back in for 2+ hours of hydration. The large inner compartments are also ideal for clothes, snacks and essentials, and the redesigned Crux reservoir is easy to fill and delivers 20% more water with every sip. Plus, the air mesh backpanel offers a close, comfortable fit with plenty of ventilation.
