How to use: Simply unfold the ARK Emergency Bivy from its stuff sack and crawl inside. It's easy to set up in no time. You can use it during unexpected bad weather or if you get stranded in the mountains. Things to note: Although it's wind and waterproof, don't use it in extremely harsh conditions for a long time. Also, make sure there are no sharp objects around that could tear it. Maintenance advice: After use, clean it with a mild soap and water if it gets dirty. Let it dry completely before folding it back into the stuff sack. Store it in a cool, dry place to keep it in good condition.
