However, you can still lose critical heat through conduction (the transfer of heat to colder surfaces around you). Thickly pad the area underneath your bivvy with as much dry debris as possible to add insulation between you and the cold ground. Find a safe spot for your shelter that is free from the risk of falling trees or rocks, running water if it rains, high winds, or other natural hazards. Foot vent. Thermo-regulated design enables you to close the bivvy to keep heat in or to open up the side and top to let heat and moisture escape.
