Vuno Austere 740 Ultralight Bivy Bag for Solo Tramping

Reliable Shelter That Weighs Just 850g – Ideal for Minimalist Adventurers.

If you're tramping in remote areas, the Vuno Austere 740 bivy bag offers essential protection without bulk. At just 850 grams, this ultralight shelter is designed for solo hikers, hunters, and emergency situations. It’s compact enough to fit in any pack and strong enough to give you cover when you need it most.

Perfect for trips where you’ll stay in huts but still want a backup shelter. This bivvy bag becomes a vital piece of gear when conditions change suddenly or huts are full. It also works well as your main shelter if you're looking to trim weight for solo missions.

Compact Design, Practical Features

Designed to work best with tapered sleeping mats, it pairs perfectly with Vuno’s own ultralight options like the Rapid Pack, Black Back, and Anti-Roll Off mattresses. The shaped floor and low-profile build keep you sheltered without adding extra volume or height.

While no tent or bivy is immune to condensation, the Vuno Austere 740 includes smart airflow options to reduce internal moisture build-up. Use it as a standalone minimalist shelter or pair it with a tarp or groundsheet for added protection in damp conditions.

Condensation Tips for Bivy Bags

Condensation is a common issue in all tents and bivies. Here’s how to reduce it:

• Keep gear away from the door to maintain airflow
• Ventilate as much as possible
• Store wet items outside the shelter
• Don’t bring hot food or drinks inside – they raise moisture levels
• Use a towel to wipe down internal condensation in the morning
• Add a tarp over your bivy bag to reduce external condensation buildup

Compatible Sleeping Mats

This bivvy bag works best with tapered ultralight mats. Pair it with our WS Camping sleeping pads.

Each of these mats complements the compact internal space and shape of the bivy for optimal comfort and space efficiency.
