Does Routine Use of a Mylar Bivvy Impact Its Efficiency?

Material Degradation

When exposed to the elements, Mylar bivvies degrade rapidly. In as little as 6-12 months, the material begins to break down, losing its reflectivity and insulating properties. This degradation is accelerated by exposure to direct sunlight, moisture, and extreme temperatures. To minimize degradation, store the bivvy in a cool, dry place and avoid exposing it to direct sunlight.

Handling Techniques

Proper handling techniques can help extend the life of a Mylar bivvy. When using the bivvy, avoid touching the reflective surface as oils from your skin can degrade the material. Instead, handle the bivvy by the edges or seams. When storing the bivvy, avoid folding or creasing the material, as this can cause permanent damage. Instead, roll the bivvy or store it in a protective case.

Maintenance and Repair

Regular maintenance and repair can also help extend the life of a Mylar bivvy. Check the bivvy for tears or punctures and repair them promptly using a patch and sealant. If the bivvy is damaged beyond repair, consider replacing it with a new one. Additionally, consider applying a coat of clear sealant to the reflective surface to protect it from further degradation.
