They have a convenient label that measures the moisture content that turns from blue to pink when they require drying out - To dry the packs simply place in the sun or put in the oven on a low heat Maximum 80 Celsius for 20 to 30 minutes. Available in 2pack and 4 pack quantities, we recommend 2 packs for smaller areas like small tents and packs and 4 packs for large tents, roof top tents etc.
