Why the name SIGNATURE SERIES? Because each bag is handmade right here in Sherbrooke, QC and signed by the person who made it. The series consists of two waterproof urban bicycle panniers i.e. the Signature H and Signature V, one super comfortable waterproof cycling backpacks, the Signature D and a small handlebar bag the Signature BB. The Signature V, H and D come with a dedicated laptop pocket and organizer, to make your bike commute safe, fun and worry-free. These urban style bike bags are made of tough and durable Cordura® nylon shell with a 100% waterproof liner. This means your belongings will stay totally dry and your SIGNATURE SERIES bag will provide years and years of reliable service.
