⚡ At a Glance
- • Thermal Retention: 26um PET film with silver coating reflects about 90% of body heat, limiting heat loss
- • Best for: Campers, hikers and emergency kits needing compact, short-term warmth solutions for two people
- • Not ideal for: Long-term sleeping or replacing a fully insulated sleeping bag for multi-night expeditions
Reflective PET film and silver coating create a heat-reflective bivvy that reduces heat dissipation. Two-piece kit includes storage pouches, whistles and metal buckles for basic emergency signalling and fastening.
Effective insulation – thanks to 26um PET film with silver coating
A thin PET film, 26 micrometres thick, uses a silver reflective layer to send a large portion of radiated body heat back toward the user. Reflectivity is cited at around 90% of body heat.
Superior heat reflection helps slow down hypothermia risk in cold conditions, making the sacks a practical short-term shelter for emergencies.
Compact two-person kit – with two sleeping bags and storage pouches
Each pack contains a pair of bivvy sacks plus two storage bags, reducing the need to buy single units for travel companions. Shared items make the kit cost-effective and simpler to stash in a rucksack.
Carrying two sacks in a single pack keeps group weight low while ensuring both people have immediate emergency shelter when needed.
Increased visibility and signalling – with bright orange colour and whistles
High-visibility orange fabric is used to improve sighting by rescuers, while two whistles and two metal buckles provide simple audio signals and fastening options.
Easier to attract attention during a rescue scenario, and whistles conserve energy while calling for help, increasing chances of rapid assistance.
