An innovative, multi-purpose piece of equipment that is indispensable for nearly every outdoor activity.
Originally developed as a survival tool for Swedish air force pilots, our patented Bivanorak is a bivy bag/sleeping bag cover, rain garment, portable windbreak, and emergency shelter, all in one and all in a 650 g/1 lb 7 oz package. The Bivanorak is made from a lightweight, tough, polyurethane-coated waterproof breathable fabric and has fully taped seams.
As a Bivy bag/Sleeping Bag Cover
The Bivanorak is cut long and wide to provide room for both a sleeping bag and pad in bivy bag mode. Its lower hem and cuffs have draw cords (those in the cuffs are elastic) which can be secured shut to keep warmth in and rain and snow out, and its long front zipper makes entry and exit easy. The large hood will easily accommodate the hood of a sleeping bag, yet it can be cinched tightly around your face. Combine a Hilleberg Bivanorak and Tarp to create a highly effective and incredibly lightweight shelter system.
As a Rain Garment
The Bivanorak is worn anorak style and can be adjusted to a variety of lengths. Simply pull the bottom hem up inside the body of the Bivanorak and tighten the draw cord around your waist. There is even enough room to carry a backpack underneath! Pair it with rain pants or chaps and you have superb wet weather protection. Its single size and easy adjustability allow both the tallest and smallest person to use the Bivanorak.
As a Windbreak/Shelter
Simply pull it out of your pack and climb in. The wind and waterproof material, adjustable cuffs and hem, and generous hood make for a roomy, comfortable temporary refuge! Its a versatile alternative to our Windsack as safety equipment for one person.Hilberg has been granted the patent on the innovative Bivanorak!
