HIKEBURGER 3F UL Gear Mummy Bivy Sack, Ultralight Sleeping Bag Cover

Ultralight mummy bivy sack for compact sleep systems

An ultralight mummy-shaped bivy sack that adds a little extra protection, helps manage condensation, and packs very small for hiking and camping.

This HIKEBURGER bivy sack is a mummy-shaped sleeping bag cover made for hikers and campers who want extra protection without carrying much weight. It weighs 200g and packs down to 6cm x 8.5cm, so it is easy to tuck into a backpack when space matters.

Shape and size that work around your sleeping bag

The unfolded size is 230cm x 90cm, and the design is compatible with various sleeping bags. The lower section fully encloses the feet to help protect the footbox, while the upper part drapes over the sleeping bag rather than closing it in completely.

Lightweight protection for condensation and dirt

The fabric is High Density Polyethylene. According to the listing, it is lightweight, breathable and offers limited waterproofing. That makes it useful as an extra layer against tent condensation and everyday dirt, but it is not recommended for use without a shelter.

Worth knowing before you buy

• This is a sleeping bag cover, not a sleeping bag.
• The listing says it should be cleaned with water only, without detergent.
• For winter camping, the open-top design can help keep the sleep setup a little less enclosed.
• It is best suited to trips where you want a small, light bivy layer rather than a fully enclosed shelter.

For camping and hiking, it gives you a simple way to add a bit of protection and warmth management without adding much bulk to your pack.
