The traditional military poncho liner provided a single function: as a lightweight blanket for adding welcome warmth to otherwise hostile and uncomfortable minimalist camping scenarios. It couldn't be worn as an insulation layer like the name might imply. Luckily this Mil-Tec(R) Multi-Function Poncho Liner takes the versatility of the original basic design to a whole new level. You can finally use it as a poncho liner during patrol (or just for extra warmth around the house). You can use it as a lightweight quilt (like the original). Two-way zipper around perimeter converts it into an emergency sleeping bag. You can also use it as a pillow or as a ground cover.
