Our Drifter Hydration Pack is another pack from Red Rock Outdoor Gear that's perfect for the field or the city. The master compartment is large enough to carry a small laptop or tablet. With an expansion zipper on the master compartment, it's sure to hold any clothing, gear, or survival essentials. Internal dividers and organizers are included on the front compartment. A zippered utility pocket is located on the both sides of the hip strap which provides access to an MP3 player, phone, multi-tool or any gear that needs to be accessed quickly. The Drifter also includes a 2.5 liter hydration bladder that can be routed over either shoulder.
