The Ortlieb Gravel-Pack is ideal for multi-day tours and self-supported races. They offer you a combined payload of 25 liters for additional gear such as supplies, food and other items. Mounting the Pack to your lowrider bike rack allows you to maintain a low center of gravity and undiminished off-road agility despite your extra gear.While the Pack’s streamlined design helps to keep it in the featherweight class, its lightweight, wear-resistant material withstands even the harshest of rock and gravel conditions you encounter on your way. And no matter how wet the weather, your things will stay dry thanks to the proven ORTLIEB-waterproof quality and roll closure.With the QL2.1 system and two mounting hooks, the Gravel-Pack remains tightly attached to your bike rack while you ride over hill and dale on your gravel bicycle, mountain bike or fatbike.
