Apidura’s Expedition Saddle Pack features all the durability and versatility of their standard packs but uses a seam-welded body made from heavy-duty waterproof materials for use in sustained wet weather. The roll closure makes makes it easy to pack up 9 liters and a non-hassle air-release vent lets the pack compress down for maximum stability and compactness. HDPE internal reinforcements ensure the pack keeps it shape with odd or loose loads and bungee webbing up top allows quick access to additional layers or a rain jacket.
