The Lifesystems Thermal Bag is a single-person emergency survival bag with a built-in radar reflector, designed to protect against cold, wind, and rain in a survival situation. Made from metallized polyester, it reflects and retains over 90 percent of body heat while the integrated radar reflector helps rescuers locate you electronically - a compact, potentially life-saving item for hikers, climbers, and anyone venturing into remote terrain.
Hand-picked by our gear specialists as a serious step up from a basic foil blanket, this thermal bag fully encloses the body to trap warmth far more effectively than a flat sheet. At 250 g it stays light enough to carry on every trip, combining insulation, waterproof and windproof protection, and high-visibility orange coloring into one dependable emergency shelter.
Who should carry the Lifesystems Thermal Bag?
This survival bag belongs in the pack of any hiker, hillwalker, climber, or mountaineer heading into remote or exposed country. It is essential emergency kit for those who could face an unplanned night out, a sudden weather change, or an injury that leaves them waiting for rescue. Trip leaders and search teams also carry these to treat casualties for cold and exposure in the field.
How does the Lifesystems Thermal Bag trap body heat?
When conditions turn against you, the bag makes a genuine difference. Climbing fully inside traps warm air around your whole body instead of letting it escape from the open sides of a flat blanket. The sealed and taped seams keep wind and rain out, the metallized lining bounces your own heat back, and the orange exterior plus the radar reflector work together to make you visible to rescuers both by eye and on their equipment.
What material is the Lifesystems Thermal Bag made of?
The bag is constructed from metallized polyester, a lightweight material that reflects radiated body heat back toward you for effective insulation. Its seams are thermally sealed and taped to prevent both heat loss and water ingress, giving you waterproof and windproof protection. The integrated radar reflector is a standout safety feature, allowing electronic detection that a standard foil blanket cannot offer.
