Order delivery may take between 3-10 days or more depending on location and type of freight service requested. We are not responsible for any delays on the delivery of orders due to delays in local customs clearances or public holidays.
Export Regulations
Australian export regulations require that the exact value of the item or items is declared and that the items are identified as dutiable merchandise for customs purposes. Under the Australian Export regulations it is also prohibited to identify any order as a “Gift” and therefore we are unable to do so even if the item has been purchased with the intention of sending to a third party as a gift.

Shelter in its essential form, the Mont Hibernator Bivy Bag is waterproof from top to toe, highly durable, ultra-compact, and campsite ready in the blink-of-an-eye.

Distinguished among other bivvies, the Mont Hibernator design is proven by over a two decades of use by the Australian Defense Force and is made entirely of waterproof, windproof, breathable Hydronaute Pro™ Fabric.
These ultralight shelters are second to none in waterproofing, breathability and performance in the field. Factory seam sealed throughout and unlike many other bivvies, the Hibernator is made entirely of waterproof breathable fabric, including the high-sided tub floor.
Climbing in and out is made easy with a large asymmetric opening. The Hibernator Bivy Bag allows quick ventilation, with double ended YKK #5 zips on both the waterproof Hydronaute Pro hood, and the bug-proof mesh interior. Zips are recessed under waterproof covers, ensuring maximum weather protection while maintaining ease of access.
You will find the Hibernator Bivy surprisingly spacious, with ample room for a large sleeping mat and a fully-lofted sleeping bag. The 3D boxfoot allows your feet to twist and turn, with sufficient room to store your boots too if needed.
