One of Catoma’s most popular and prolific products is the Wolverine EBNS, formerly known simply as the EBNS. The Wolverine Rainfly Kit is added to the Burrow to create the Wolverine EBNS. 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. The greatest feature of the rainfly kit is its spacious dual vestibules. The entry side door opens wide to allow easy entry, and the storage side door offers a wider vestibule for storing a full size pack with room leftover.
