Bivy Sack Tent – Vuno Austere 740 Bivy Bag with Hoops Only 820g

Ultralight shelter for hut trips and “just in case” nights out

The Vuno Austere 740 is a lightweight bivy sack tent (often called a bivvy bag in New Zealand) for trampers and hunters who pack for huts, yet plan for the unexpected. Because weather changes fast in New Zealand, this bivy gives you quick solo shelter when you get delayed, take a wrong turn, or choose to stop early.

It uses simple hoops, so you can pitch it quickly on uneven ground.

Fit and sleeping mat guidance

Tapered air mattresses fit best inside a one-person shelter like this. They sit neatly in the foot area, and they leave more room around your shoulders. Our Rapid Pack, Black Back, and Anti-Roll Off tapered mats fit well, so you can keep your sleep kit light and tidy.

Benefits

1. You carry a backup shelter while still keeping pack weight low.
2. You can sleep solo near a hut, on the track, or at a hunting spot if plans change.
3. You get a quick setup that suits tight campsites.
4. You help protect your sleeping kit from wet ground overnight.
5. You can pair it with a tapered mat for a better fit and more comfort.

Condensation in real conditions

Condensation can build overnight in most tents and shelters. While you sleep, you breathe out moisture, so the inside can feel damp by morning. Therefore, airflow matters as much as waterproof fabric.

Tips to reduce condensation when using the bivy

• Do not block the entrance with gear.
• Encourage airflow through the shelter.
• Keep wet gear outside where possible.
• If you bring warm food or drinks inside, ventilate well.
• Use a small towel to wipe the ceiling if moisture forms.
• In wet weather, use a groundsheet or tarp over the top to help manage splash and moisture.
