Lightweight Waterproof Bivy Bag

Built from durable, breathable nylon with a 5000 mm hydrostatic head and taped seams, it can be used as a standalone weatherproof shell or as a protective cover over your existing sleeping system.

Compact enough to live in a pack year-round, the bivy bag provides an extra layer of defence against rain, dew and ground moisture for Defence, law enforcement, remote workers and outdoor professionals operating in variable conditions.

Why Teams Choose the Bivy Bag Standard

Fully waterproof protection: Rated to a 5000 mm hydrostatic head with taped seams, the bivy bag helps keep your sleeping system dry in wet ground and rain.

Breathable nylon fabric: The 100% nylon shell is breathable, helping reduce condensation build-up inside the bag when used in cooler or damp conditions.

Use alone or with a sleeping bag: Can be used as a minimalist shelter by itself or as a tough, waterproof outer shell over a standard sleeping bag to improve weather resistance and durability.

Lightweight and compact: At around 300 g and packing to about 13 x 10 cm, it takes up very little space in a rucksack, patrol pack or vehicle kit.

Standard and extra-long options: Manufactured in standard and extra-long versions, so taller users can select a more suitable length if required (extra-long weight approximately 320 g).

Supplied with stuff sack: Comes with its own stuff sack for neat storage, making it easy to compress andstow w hen not in use.

Frequently Asked Questions

Is the bivy bag fully waterproof?

Yes. It has a stated hydrostatic head rating of 5000 mm and taped seams, meaning the fabric and seams are designed to be fully waterproof under normal field conditions.

Can I use it without a sleeping bag?

Yes. In milder conditions it can be used as a simple bivouac shell on its own. In colder weather it is usually used as a waterproof outer around a standard sleeping bag and sleeping mat.

What is the difference between the standard and extra-long versions?

The standard version weighs about 300 g, while the extra-long version weighs about 320 g and is designed for taller users. Both share the same fabric, waterproof rating and general design.

How small does it pack?

The supplied stuff sack compresses the bivy down to roughly 13 x 10 cm, small enough for most rucksack pockets and vehicle grab bags.

Is it suitable for Australian conditions?

Yes. The olive bivy bag is well suited to Australian bush, high country and desert edges as a lightweight waterproof shell. As with any bivy, you should manage condensation, temperature and insect protection according to local conditions.

Can it be used with any sleeping bag?

The design is a general-purpose bivy shell and will work with most standard mummy or rectangular sleeping bags, provided they fit within the bag’s dimensions.
