Product description

Extremely light and packed small: the Bivybag 100% VentAir is the breathable bivy bag for protection from rain, wind and condensation. With its low weight and small pack size, this bivy bag fits in any backpack.

It is made entirely of VentAir 3-layer fabric, which makes it not only waterproof, but also extremely breathable.

The roomy 3D hood is not only comfortable, but also offers room for some additional gear. An incorporated aluminum wire provides comfortable headroom and a mosquito net ensures airflow and protects against insects.

Due to the wide 3D foot section, there is also room for a voluminous sleeping bag. Both on the hood and the foot part are three suspension loops, with which the bivy bag can be hung up.

What does the water column value mean?

Water column or hydrostatic pressure is a unit of measure used to describe the waterpoofness of fabrics. A 10 cm² fabric sample is tensioned under a water cylinder. The point under which droplets are pressed through the fabric indicates the water column.
