The reason Gewa SPS cases are so robust is a result of their clever design. Gewa SPS (Side Protection System) cases consist of a fibreglass inlay worked into the external Cordura fabric. Not only does the fibreglass offer exceptional protection, but it also keeps the bag lightweight.
For extra protection, SPS bags have a coating of 20mm highly-compressed foam padding. This padding combined with the fibreglass inlay and high-quality Cordura fabric come together to produce a case that will not only stand the test of time, but will protect your instrument.
