With no zippers, drawcords or hook-and-loop to disrupt your sleep, this spacious bag sleeps 2 people comfortably and has a soft comforter that drapes naturally around you, just like your bed at home.

  • Features

    • Sleeping bag design eliminates all zippers, drawcords, toggles and hook-and-loop closures
    • Oversize comforter seals the opening and drapes naturally around you so you can sleep comfortably in any position: back, side or stomach
    • On warmer nights, flip the comforter outside the sleeping bag and tuck it back for ventilation; insulated hand / arm pockets provide warmth when comforter is outside the bag

    • Synthetic insulation is warm and durable, and insulates even when damp

    • Adjustable sleeping pad sleeve on the bottom of the bag secures either two 20 in. pads or two 25 in. pads (pads not included)
