Ortovox says about the Bivy Ultralight
A sudden change in the weather, an unforeseen event or an unplanned night in the mountains: A Bivi bag protects you just when it really matters, and belongs in a mountain climber’s basic equipment.
Our BIVY ULTRALIGHT is for all those who spend a lot of time in the mountains and need every gram of weight to count. Our bivi bag weighs only 150 grams and has a minimal pack size. The BIVY ULTRALIGHT is suitable for one to two people and protects from the elements: It is windproof and, thanks to the PU coating, also water and dirt resistant. The silver coating on the inside, which reflects body head, keeps the cold out.
This means the small bivi bag can provide critical protection in case of an emergency.
