Heatshield Bag

If you’re out on a day hike or away from your base camp and benighted, constant rain, wind-chill and ultimately hypothermia can literally be the death of you. Don’t let that happen! Carry this ultralight survival shelter from UK stalwarts Lifesystems and drastically improve your chances of survival. In case of emergency, wrap your body and head in the metalised polyester which will protect you from rain, wind and body heat loss with its taped seams and reflective surface. The bright colour and radar-reflective material will help rescue services locate your still-breathing body. It’s reusable should you ever make the same mistake twice, and comes in a handy ripstop storage sack.
