FAQ

Is it suitable for extreme conditions?

Not recommended as the sole shelter in extreme winter conditions or prolonged storms. It protects from wind and rain but does not offer the insulation or stability of a 4-season tent.

Can it be used year-round?

Perfectly suitable for 3 seasons. In winter, it becomes useful as a complement to a technical sleeping bag and an additional shelter.

How to maintain it to ensure its longevity?

Clean with water, dry in the shade, re-waterproof with DWR as needed, and store dry. Avoid washing machines and dryers.

What is the difference with a small tent?

The bivy sack is lighter and more compact. A tent provides more space, ventilation, and stability in bad weather.
