No one wants to carry a water bottle when heading uphill for a day on the trails or on a long-distance run. Instead, investigate buying a hydration pack that will provide hands-free hydration. Simply slip on one of these sleek outdoor backpacks and stash up to an entire day’s worth of water (along with maybe some snacks).
Unlike LifeStraw’s Peak Series Water Filters, hydration packs are specifically designed to hold and transport water. The best hydration packs are lightweight, with an ergonomic shape for easy carrying, as well as a drinking tube so you don’t have to slow down to take a sip of water.
When shopping for the best hydration pack, you’ll want to consider the type of activity for which you’ll be using it, examine the hydration backpack’s water capacity and design and if it comes with tubing that is easy to disconnect.
Here are the best hydration packs for whatever outdoor activity you undertake.
