Milspec Poncho Liners with ties, also known as Woobies, are designed to provide warmth and comfort in mild temperatures when used with a poncho. The multipurpose poncho liner also works great as a camping sleeping bag or blanket. Ties in each corner enable you to easily attach the 62 inch x 80 inch woobie to your poncho. The poncho liner is constructed from soft yet durable rip-stop materials for years of reliable use and makes a great addition to your bug out bag or camping pack.
