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.


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.

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 or tuck the extra fabric under your pack’s hip belt. 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.
