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.

For stuff sack options, consider our Context Organizer.

  • Anchor System

    18 attachment points around the circumference allow the Bastion Woobie to be attached or anchored using the included cord ties, paracord, zip ties, or carabiners. Examples:

    • Wrap the Bastion Woobie around your body and anchor to itself for hands free mobility.

    • Anchor the Bastion Woobie to surrounding environment to create field expedient shelter.

    • Attach the Bastion Woobie to sleep pad to minimize shifting while sleeping.

  • Thermal Regulation

    Polartec® Power Fill™ is a soft and pliable matrix of polyester engineered with a proprietary hollow fiber construction that is softer and more durable, forming thousands of air pockets that continuously capture and contain body heat, while maintaining a resilient, equalized thermal layer between the colder air on the outside and the warmer temperatures on the inside.

  • Moisture Management

    The DWR treated shell works in conjunction with the hydrophobic properties of Polartec® Power Fill™ to resist moisture absorption and dries quickly, while maintaining a high warmth to weight ratio.  Made with industry-leading, cruelty-free, 80% post-consumer recycled content, Power Fill™ insulation technology provides greater warmth retention in colder conditions, without added weight or bulk.
