The Stretto system is a very high quality Swiss made humidity control system.
The Stretto bag is charged periodically with de-ionised water and also fixed, inside its container, to the lid of the instrument case. A finely controlled humidity level can then be maintained within the case.
This system is rapidly becoming the humidifier of choice for professional musicians.
The Stretto utilises special humdifying bags which when placed in water become a gel which releases moisture in a progressive manner. They can be re-used several times before needing replacement.
