The Cortech Super-SP 10-12L Expandable Tank Bag is engineered for riders who need dependable storage, weather resistance, and adaptable carrying capacity. Built from waterproof 1000D Cordura® ballistic nylon with a DWR-coated outer shell, the Cortech Super-SP 10-12L Expandable Tank Bag is designed to withstand demanding riding conditions while protecting your gear. Its semi-rigid construction features EVA foam-backed reinforced side walls and a 3D-molded top lid to maintain shape and add structure on the bike. A hidden expansion panel increases carrying capacity from 10 to 12 liters when extra room is needed, while the waterproof main compartment with YKK® Aquaguard zippers helps keep essentials protected from the elements. The low-profile angular shape reduces drag and maintains a clean fit on the tank, while dual side pockets, internal organizers, and a MOLLE-compatible top panel improve storage flexibility. Included magnetic and strap mounting systems provide multiple installation options, while hideaway backpack straps make carrying the Cortech Super-SP 10-12L Expandable Tank Bag easy once off the bike.
