Abstract: A comfort guard apparatus and method of use comprises a compartmentalized chamber positioned adjacent to protective equipment such as shin guards, chest protectors, and helmets. In one embodiment, the apparatus is interchangeable and removably positioned between the user and the protective equipment. In another embodiment, the apparatus is built in to the protective equipment including clothing such as shirts and pants. The apparatus can be replaced with a freshly cooled or warmed version during use. The apparatus conforms to the body of the user, keep the chamber in contact with a greater surface area, and prevent the contents of the compartments from gravitating towards edges. Adjacent compartments can be separated by a breakable membrane or contain breakable packets. The apparatus cushions the user from abrupt edges of the protective equipment. The apparatus, positioned against the body of the wearer, regulates the wearer's body temperature which contributes to enhanced athletic performance.
