Every Signature campsite comes with a Coleman Sun Shower. The sun shower has a reservoir that holds up to 5 gallons of water, potentially enough for multiple showers. It's constructed of heat-locking material that warms the water when it's left in the sun, even on cool days. The shower features a strong handle for reliable hanging and carrying as well as a handy on/off shower head valve to conserve water.
Simply fill the reservoir with water, leave it in the sun for a while to warm up, hang the bag then enjoy!
