An evolution of the classic US military poncho liner, the Bastion Woobie brings modern technology to this field comfort staple.

Made in the USA and insulated with Polartec® Power Fill™, Bastion maximizes heat retention with less bulk and weight. Easily stowed in your kit until needed, Bastion provides instant comfort when the mercury drops. Power Fill's less-bulky insulation means that the Bastion Woobie takes up less room in your pack than equivalently warm synthetic insulation.
