The Burrow’s instant deployment and cot compatibility make it an efficient, fast-access shelter to protect users from insects and a great shelter for medical patients in the field. It is EPA registered and has Permethrin bonded to the material for insect repellency. The Burrow is supported by a strong and ultra-light .134” diameter pultruded fiberglass rod which winds through the shelter, expanding it to its given shape. When the rolled up Burrow’s cinch strap is removed, the shelter is released and snaps into shape automatically. No assembly or set-up is required.
