What Our Gearhead(R) Experts Are Saying:"This pack is a perfect way to add storage without cluttering the frame. I use it for my small sleep system or an extra water bottle on long rides. It's securely attached, and I don't worry about it shifting on rough trails. The waterproofing has been great for keeping everything dry, even in heavy rain."When our rides stretch into the backcountry, the Apidura Backcountry Downtube Pack steps up as an adaptable storage solution. This low-profile pack attaches seamlessly to the downtube, creating an extra compartment that's perfect for essentials, spares, or even a water bottle when frame space is limited. Its single-motion attachment makes it easy to secure and remove as needed, and the reinforced waterproof construction keeps contents clean and dry on muddy trails and through streams. With a roll-down closure that adjusts to our load, we're able to carry everything from tools to an entire sleep system, ready for wherever the trail takes us.
