A sleeping pad is a portable, cushioned mat designed to provide comfort and insulation while sleeping outdoors. It is commonly used by campers, hikers, and backpackers to create a barrier between the ground and the sleeping bag, helping to retain body heat and improve overall sleep quality. Sleeping pads come in various materials, thicknesses, and sizes to suit different preferences and activities. These pads can be inflatable or foam-based, with inflatable options offering adjustable firmness and compact storage. Many sleeping pads are lightweight and easy to carry, making them an essential piece of gear for outdoor adventures. Popular brands include Therm-a-Rest and Sea to Summit.
