The Stretto from Switzerland is an effective system for maintaining a safe and consistent humidity level in a case's interior. The Stretto bag effectively humidifies for up to two weeks. When ready to rehydrate the bag, simply re-soak in water (use distilled water for best results). Benefits to the player include an instrument safer from the risk of cracks, more consistent performance, and bow hair that does not dry and shrink.

Available for Violin/Viola, Cello & Double Bass.

The Humidifier comes with 2 spare bags and the bags can also be purchased separately. Hygrometer also available separately or as a package twinned with a humidifier if required.
