What Is a Vapor Barrier Backpacking?

By Robert Palmer

A vapor barrier backpacking system is a type of clothing system designed to protect you from the elements during backpacking trips. It works by trapping your body heat and preventing it from escaping. This keeps you warm and dry during cold or wet conditions, allowing you to enjoy your backpacking trip without having to worry about getting too cold or wet.

The most basic type of vapor barrier system consists of a jacket and pants that are made from a material that is both waterproof and breathable. This material is usually a synthetic fabric such as GORE-TEX® or Polartec®.

A vapor barrier jacket typically has gusseted armholes, which helps keep wind and moisture out, as well as adjustable cuffs at the wrists, which can be tightened to keep out even more wind and moisture. The pants should have an adjustable waistband with drawstrings, as well as reinforced knees, seat and ankle cuffs for additional protection against the elements.

In addition to the jacket and pants, some people also choose to use a vapor barrier liner (VBL). A VBL is a thin membrane layer that goes between your base layer and insulation layers.

It helps prevent your body heat from escaping by trapping it inside the insulation layers. VBLs are typically made from thin fabrics such as nylon or polyester.

When selecting a vapor barrier system for your backpacking trip, it’s important to consider both comfort and functionality. Some jackets may be more comfortable than others, but they may not provide enough protection against the elements.

Additionally, some pants may be lightweight but not offer enough protection against wind or rain. Be sure to research different types of jackets and pants before making a purchase in order to ensure that you get the best possible combination of comfort and protection.
