Hydration packs are the perfect accessory for any serious hiker or outdoor adventurer. A hydration pack is essentially a backpack with a reservoir to keep water. Using a long straw, you can take sips from the pack without using your hands, or having to stop and search through your pack for a drink bottle. The Outrak Vapor Hydration pack is a high quality hydration pack perfect for any outdoor adventurer. With a 3L capacity, this pack can hold enough water to keep you hydrated throughout your adventure. You will love the lightweight construction and padded back panel, adding comfort when hiking, walking or exercising. Adjustable shoulder, sternum and waist straps allows for a comfortable, yet secure fit on the go. A large storage compartment has been included to store your food and safety gear, whilst smaller pockets have been included for your essentials, such as your keys and sunglasses.
