One of our two quilt offerings, the 40-Degree Quilt is the perfect ultralight backpacking quilt for three-season temperature ranges, providing even, top-to-bottom warmth. A 7d micro ripstop shell is durable and soft to the touch, and a sewn, closed footbox helps to prevent drafts. Low-profile center push clips and a neck drawcord work together to lock in warmth. Pair with an 8L Side Entry Pod for maximum, space-saving packability. 

Key Features:
  • High-performance, responsibly-sourced 1000 fill power down with DWR treatment for moisture protection.
  • Three-dimensional baffles (vertical on upper body, horizontal at the footbox) keep maximum loft and mitigate down migration.
  • Includes two separate pad attachment straps to secure the quilt to a sleeping pad, preventing drafts during active sleep.

WHY CHOOSE THE 40-DEGREE QUILT?

    How?

    How can a quilt be this light?

    How can something that is this light, be so warm? How can something basic like a sleeping bag be made so luxurious?

    I don't know. But the crew at HMG sure do!

    It feels massive while sleeping inside. There was a heavy dew on night and despite my bag being soaked wet in the morning...I was dry and cozy.

    How can my bag get wet and I stay dry???

    Love this bag and how well it stays in place
