Quick Answer
Mylar Bivys can be used in extreme weather conditions, but only if properly set up and maintained. They are not as durable as other shelters, and may tear or leak in strong winds or heavy rain. However, with the right techniques and equipment, a Mylar Bivy can provide a surprising amount of protection.
Setting Up a Mylar Bivy for Extreme Weather
When setting up a Mylar Bivy in extreme weather, it’s essential to secure the edges and corners with rocks or stakes. This will prevent wind from lifting the fabric and causing it to tear. Use at least three stakes per corner, spaced about 12 inches apart, and make sure they are driven into the ground at an angle to prevent the fabric from sagging.
Choosing the Right Location
When choosing a location for your Mylar Bivy, look for a spot that is partially sheltered from the wind and rain. Avoid areas with standing water or where water tends to collect. If possible, set up your shelter in a small depression or a spot with a slight overhang to provide additional protection from the elements.
Maintenance and Repair
In extreme weather, it’s crucial to regularly inspect and maintain your Mylar Bivy. Check the seams and corners for signs of wear or damage, and make repairs as needed. Use a waterproof repair kit to seal any holes or tears, and apply a layer of waterproofing spray to the fabric to help protect it from the elements. If your shelter is damaged beyond repair, consider replacing it with a more durable option.
