    A little something extra.

    Slide your Therm-a-Rest Sleep Liner into your bag and enjoy an extra 5 degrees of warmth on a chilly night in the woods. The brushed polyester is super soft against your skin and easy to throw in the wash between uses, while the sewn-in loops let you add a quilt or blanket to customize your setup.

    • A soft liner to add extra warmth at night
    • Polyester construction is warm and breathable
    • 3/4-zip for easy entry and exit
    • Item #CAS00D6

    Foot Box Too Small

    • Familiarity: I returned this product before using it

    Therma-Rest makes great products and the quality and workmanship was there with this sleeping bag liner, however unless you really want to feel like a wrapped mummy from the knees down beware the manufacturer's sizing for the foot box. Way too small for comfort and movement. Better off with a rectangular liner that matches close your mummy bag dimensions.
