The Giant Shadow Seat Bag (Medium) is designed to carry everyday ride essentials in a clean, stable under-saddle setup. It offers more room than a minimalist wedge bag without becoming bulky or getting in the way while pedaling.
This bag is a solid choice for road, gravel, and fitness riders who want organized storage, easy access, and a secure mount that stays put over rough pavement or light trail use.
