Special Notes
1. Always pack one complete spare day's
food in case of emergencies and/or have a
couple of self heating food packs.

2. Re-pack food into plastic bags to reduce
waste and weight but remember to keep instructions.

3. Ensure you have suffiicient gas for cooking
and always cook in a ventilated area.
