A wrong turn, a rolled ankle or weather that moves in early can turn a day hike into an unplanned night out.
With an emergency bivvy in the lid of your pack, you can get out of the wind and rain and hold on to your own body heat while you wait for daylight or for help.
A car that sits still in freezing weather gets cold inside fast.
With an emergency bivvy in the glove box, you can climb in right away and keep your own body heat while you wait for help or for the plow.
In a long winter power outage, the temperature indoors drops hour by hour.
Keep one emergency bivvy per person in your home emergency kit, and lay blankets over it if the evening gets long.
Put something insulating under you: a sleeping pad, a jacket or the car's floor mat. The ground and a car floor pull a lot of heat.
Keep your head and face outside the sack so you breathe fresh air, and lay blankets or extra jackets over the bivvy. A little condensation on the inside is normal, because the film does not let moisture through.
This bivvy is made for emergencies. It does not replace a sleeping bag, and it has no temperature rating.
For a planned night outdoors you need a real sleeping bag and a sleeping pad. Our guide How to sleep warm in a tent walks through the whole sleep system.
Unfolded, the bivvy measures 83 x 35 in (210 x 90 cm) and is 71 in (180 cm) around. Packed in its stuff sack it measures 2.75 x 4.25 in (7 x 11 cm), and bivvy and stuff sack together weigh 4.4 oz (125 g).
No. It is made for emergencies and has no temperature rating. For a planned night outdoors you need a real sleeping bag and a sleeping pad. The emergency bivvy is what you carry for the unexpected.
A little condensation can form, because the film does not let moisture through. A cold body at rest gives off less moisture than a warm body on the move, so in the situations the bivvy is made for it tends to be less noticeable. Keeping your head and face outside the sack reduces it further.
Orange is easy to see against snow and forest, which helps if someone is looking for you. Green blends in if you would rather keep a low profile, for example when hunting.
Call emergency services right away: 911 in the US and Canada, 999 or 112 in the UK, 000 in Australia. Confusion, slurred speech, clumsy movements and shivering that stops are serious signs. No piece of gear can guarantee that someone gets through severe cold, but holding on to body heat helps while you wait for help.
