Abstract: A reusable face mask with a foam face seal to protect against transmission of airborne pathogens. The face mask uses an easily interchangeable, readily available, non-proprietary, standard filter. It has a section specifically designed to mitigate the fogging of glasses, and has a user-interchangeable strap/harness system.

Abstract: A belt buckle with an embedded power source, such as battery(s), and an attached or embedded light source, such as light emitting diodes, for illuminating an area in front of a user, such as a hiker, climber, or trail-runner. The buckle is typically a side-release plastic buckle, and is typically mounted centrally on a pack's hip-belt. The light is adjustable vertically, or has a lens to produce a tall, narrow beam of light for the purpose of illuminating a large section of trail.
