Discovery is the lightest weight collection of professional-level bags that Tenba has ever created. Built to our legendary "Crafted Without Compromise" standard, Discovery bags are the perfect carrying solution for photographers who want to walk, bike, hike or climb with their gear - activities which truly require the lightest bags available. Weighing only 2.6 pounds, the Discovery Large Photo/Laptop Daypack is remarkably lightweight, yet it fits a professional-size DSLR system, including cameras with a booster/grip. And the light weight comes without sacrificing quality or protection, as the bag is built with rugged, weather-repellent nylon and self-healing zippers. There is even a waterproof bottom panel to keep the bag protected if it has to sit on a wet surface.
