Why would I need desiccant?
To absorb condensation in humid conditions.
In humid climates there will be moisture in the air sealed inside the case. With cameras, this moisture tends to condense inside the lens. Desiccant sachets will absorb any such moisture, keeping the contents completely dry.
Many of our cases come ready supplied with one or more desiccant sachets. We recommend use of desiccant sachets in all Aquapacs in humid climates.
