Quick Answer
Protect sensitive gear from moisture in extreme cold by storing it in airtight containers or dry bags, ideally with silica gel or desiccant packets to absorb moisture. Seal containers in plastic bags or wrap them in dry towels for added protection. Store these containers in a dry, insulated area away from direct cold.
Waterproof Containers
Use containers rated to withstand extreme cold, such as airtight plastic bins or Pelican cases, to store sensitive gear. Look for containers with a waterproof seal and consider adding extra protection like silica gel packets or desiccant bags. For example, a 5-gallon plastic bin with a waterproof seal can store a laptop, power bank, and other essential gear.
Desiccant and Drying Agents
Utilize silica gel packets, desiccant bags, or instant drying agents like Dri-Z-Air to absorb moisture. Store 1-2 packets or bags per container, depending on the size, to maintain a dry environment. Check the packets or bags regularly and replace them every 3-6 months or sooner if you notice reduced effectiveness.
Insulation and Storage
Store waterproof containers in insulated areas, such as a thermally insulated backpack or a dry, insulated cabinet. Maintain a consistent temperature range between 32°F and 50°F (0°C and 10°C) to slow down moisture buildup. Consider using a temperature-controlled storage unit or a thermally insulated cooler with dry ice for prolonged storage.
