This is the USA made/Berry Compliant version on the Burrow. This model’s materials are the same as the regular version. All the materials and labor are done in the USA. The Wolverine Rainfly Kit can be added to the Burrow to create the Wolverine EBNS, our other contract heavy-hitter. The greatest feature of this rainfly 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. With the common sense re-design of the Wolverine rainfly, we also decided to offer a common sense way to purchase it. Separately. The NSN for the full EBNS is still relevant, but now customers can purchase the Rainfly Kit on its own to pair with their existing Burrow.
