Product Description

When you’re on the trail, reach for a daypack that can keep up; the RMU Core pack Performance Hiking Backpack. Purpose built for treks, hikes, and trails, this hiking backpack has it all. Weatherproof 420D nylon fabric offers the perfect balance between long term durability and lightweight comfort. Multiple built in pockets and straps keep you organized. The full height side zippers provide easy access to the main compartment and the large front pocket is loaded with straps and slip pockets to store your gear. This travel backpack is designed to withstand an outdoor adventure but doesn't have to stay off roads. The sleek design and organization pockets make it great for urban exploring as well. The hydration reservoir doubles as a laptop sleeve and the waist belt can be removed when you take it from the trail to the street.
