Introducing the Missile Hydration Pack, brought to you by Outrak! 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 Missile Hydration Pack features a 2L capacity, keeping you hydrated throughout your adventure. Made from lightweight polyester and ripstop, it can also fit comfortably under your pack without adding much weight. The team at Outrak have developed this pack with a lightweight mesh harness to ensure that the pack is comfortable and breezy. If you are looking for convenient hydration on the go, look no further than the Outrak Missile Hydration Pack!
