Cocoon Vapor Barrier Liner

Description

The Hooded Vapor Barrier Liner is a body vapor-tight liner designed by Cocoon.
In cold weather, this vapor can condense and soak into the down. This affects its thermal performance. The role of VBL is to prevent this from happening.
Made from non-breathable 20 denier nylon, the Cocoon bag sheet is laminated with a TPU film on the inside. It slips inside the sleeping bag and is particularly useful for polar expeditions (high mountains, Lapland, Patagonia...).

When using a Vapor Barrier Liner, we recommend wearing clothing to avoid skin contact.

The Vapor Barrier Liner Cocoon is :
- Adjustable hood with drawcord
- Can be used as an emergency bivy
- Compact and lightweight
