Gewa 20" x 16" SPS Bass Drum Bag
The Gewa 20" x 16" SPS Bass Drum Bag is a professional-grade protective case designed for standard-depth 20-inch bass drums. It utilizes Side Protection System (SPS) technology and military-grade materials to ensure instrument safety during transit and storage.

Overview and Material Composition
The Gewa SPS Bass Drum Bag is engineered for drummers seeking a high level of protection without the bulk of a traditional hard-shell case. The exterior is constructed from 1680 Denier CORDURA nylon, a synthetic fabric originally developed for military-grade body armour. This material is highly regarded for its resistance to tearing and abrasion, making it suitable for the rigours of frequent touring.
The 'SPS' designation refers to Gewa's Side Protection System, which incorporates reinforced fibreglass inserts into the walls of the bag. This provides a structural rigidity that bridges the gap between a standard soft gig bag and a moulded flight case.
Protective Features
Beyond the outer CORDURA shell, the bag features a multi-layered interior designed to shield the drum's finish and hardware. It includes 20mm of thick foam padding to absorb impacts and vibrations. The innermost layer is a soft fleece lining, which prevents scratches to the lacquer or wrap of the drum shell and protects the chrome hardware from scuffs. The combination of dense foam and fleece ensures the drum remains secure even when transported in a packed vehicle.

Ergonomics and Transport
Despite its rugged construction, the bag is designed for ease of mobility. It features multiple carrying options to suit different scenarios:
- Shoulder Strap: An adjustable strap equipped with a shoulder pad to distribute weight during longer walks.
- Soft Carry Handle: A cushioned handle intended for short distances or quick lifting from a van.
- External Grip: Reinforced points to assist in manoeuvring the drum into tight storage spaces.
Target User and Suitability
This bag is primarily aimed at gigging professionals and students who require reliable protection for a 20" x 16" bass drum. It is particularly well-suited for drummers who transport their own gear in private vehicles, where the bag protects against the 'rolling around' common in the back of a van. While it offers more protection than budget alternatives like the Gear4music Rock Fusion sets, it remains more portable than heavy-duty flight cases.
