Montbell Tyvek Sleeping Bag Cover

Purchased at Montbell Outlet in August 2025 for ¥5,700, but I'm listing it as I don't anticipate having a chance to use it. It's brand new and unused, only unfolded indoors.

Specifications below:

This is a lightweight and portable sleeping bag cover. It has moderate breathability and moisture permeability, making it resistant to water absorption and protecting your sleeping bag from dampness and condensation, supporting a comfortable sleep. Cannot be used on its own. *Not waterproof.
