The Polycryo groundsheet is made in the United States by Gossamer Gear<\/a>. It is one of the simplest and lightest ways to protect the floor of your tent, tarp, or sleeping pad from moisture, dirt, and minor ground abrasion.<\/p>\n

Its main advantage is its extremely low weight. It can easily be trimmed to the exact size of your shelter to provide effective protection without adding more than a few grams to your pack.<\/p>\n

\n

When to use it<\/h2>\n

Polycryo makes sense when you want to protect the floor of an ultralight tent, a tarp, or an inflatable sleeping pad. It helps reduce wear caused by rocks, roots, branches, or abrasive ground.<\/p>\n

It also prevents ground moisture and dirt from coming into direct contact with your gear. It is especially popular among long-distance hikers for its excellent balance of weight, pack size, and protection.<\/p>\n

\n

Design<\/h2>\n

The sheet can easily be trimmed with scissors to fit any tent or shelter. It also does not fray or require any special edge finishing.<\/p>\n

For best results, it should be trimmed slightly smaller than the footprint of the shelter. This prevents it from sticking out and collecting rainwater underneath the tent.<\/p>\n

\n

Made of Polycryo<\/h2>\n

Polycryo is an ultralight plastic film commonly used as a groundsheet in ultralight hiking. It stands out for offering good tear and puncture resistance while keeping weight extremely low.<\/p>\n

In addition to being transparent and compact, it does not absorb water and dries very quickly. Once folded, it takes up very little space inside your pack.<\/p>\n
