Know before you buy
The bivy features specialized arm openings that allow you to extend your arms outside the shelter while keeping the rest of your body enclosed. This design lets you sit up to cook, read, or adjust gear without exposing your sleeping bag to the elements or bugs.
Yes, it is rated for four seasons. The waterproof, breathable fabric and taped seams provide the necessary protection against snow and wind, though you should ensure you have a sleeping pad with a high R-value to insulate against the cold ground.
Bivies are inherently snug, but this model includes a hooded design and an adjustable visor to create a bit more breathing room around your face. The mesh window also helps reduce that closed-in feeling by allowing for better airflow and visibility.
The bivy has a minimum weight of 1 lb 5 oz and a packaged weight of 1 lb 6 oz. It is a very lightweight alternative to a traditional tent, making it ideal for fast-and-light backcountry trips where every ounce counts.
While you technically can, it is not recommended. A sleeping pad is essential for both insulation from the ground and to provide a bit of structure to the bivy, which helps keep the fabric off your face while you sleep.
It uses waterproof-breathable fabric to manage moisture, but condensation is always a risk in a small, enclosed space. The adjustable visor and multiple zipper sliders allow you to customize airflow, which is key to minimizing moisture buildup inside.
