02 Quick Setup
5 StepsFind flat, sheltered ground clear of sharp rocks, sticks and debris that could puncture the material.
Use a sleeping pad, pack, spare clothing or other dry insulation to reduce heat loss to the ground.
Remove the bivvy from its stuff sack and open it with the reflective silver surface facing inward.
Slide in carefully and pull the bivvy to your shoulders. Keep your face completely unobstructed.
Gather the open end loosely around your upper body while maintaining a clear fresh-air opening.
Never cover the face or fully seal the bivvy around an occupant. Always maintain a clear opening for fresh airflow.
03 Stay Warm & Visible
Reduce Heat LossWarmth & Moisture
- Keep the reflective silver surface facing inward.
- Use dry insulation beneath you before entering.
- Keep the bivvy comfortably close to the body without restricting movement.
- If moisture builds, increase the ventilation opening.
Visibility & Position
- Keep the high-visibility orange exterior facing outward.
- Choose sheltered ground away from drainage paths and overhead hazards.
- Remain visible to rescuers when safe to do so.
- Do not place the bivvy near flame, sparks, stoves or other heat sources.
The reflective layer reduces radiant heat loss, but it does not generate heat. Ground insulation, dry clothing and protection from wind remain important.
04 Care, Cleaning & Storage
Dry Before Packing- Clean gently. Wipe with a damp cloth. Avoid harsh chemicals, solvents and abrasive scrubbing.
- Dry completely. Air dry before repacking to reduce odour and moisture damage.
- Store protected. Keep in a cool, dry place away from direct sunlight and extreme heat.
- Inspect regularly. Check after use for pinholes, tears, brittleness or damage to the reflective surface.
- Repair or replace. Patch small tears with suitable waterproof repair tape. Replace a badly damaged bivvy.
05 Important Safety
Emergency Shelter OnlyDesigned as temporary emergency shelter, not as a substitute for an appropriate sleeping bag and shelter on planned overnight trips.
Polyethylene film can melt or burn. Keep the bivvy well away from campfires, stoves, sparks and other heat sources.
Never cover the face or fully seal an occupant inside. Maintain a clear fresh-air opening at all times.
Thin shelter material can create suffocation or entanglement hazards. Keep away from small children unless closely supervised.
Enter and move carefully. Sharp objects, footwear and rough ground can puncture or tear the material.
06 Troubleshooting & FAQ
Fast FixesConfirm the material is intact, the reflective surface faces inward, dry ground insulation is available, the face will remain unobstructed and the bivvy is well clear of flame, sparks and heat sources.
