Experienced Sierra hikers know: a headnet is the simplest, no-nonsense way to keep mosquitos and flies away from your face and neck. This UltraNet from Ben's is a high quality head net featuring a very fine mesh that makes it easy to see through, but locks out bugs. Pair this head net with a baseball or sun hat to keep it lifted off your face for comfort. This is also a great way to avoid using repellents like DEET around your gear and sunglasses.
