The Extreme Winter Series of Toaster Under Quilts is designed to be used in the Canadian Winter Months.

*Please note that you, the user needs to be familiar with cold weather camping and the Extreme Winter Toaster UQ is part 1 of your overall winter camping/sleeping kit. Extreme cold weather has it’s own natural hazards, please be aware.

The Toaster Extreme series uses a 15D/20D fabric which gives excellent wind resistance for your quilts and can handle the cold weather.

 To install simply clip the provided S-biners onto the end loops of your hammock and adjust the height using the line locs on the corners of the quilt. From there simply cinch up the end channels to prevent air movement.

  • The Toaster Underquilt implements a closed baffle design. This means there are no gaps on the inside that could let down move chamber to chamber
  •  All of the quilts are overstuffed with 35% more down to help with loft during the cold where you may have some frost build up. This helps in maintaining loft over time and helping in keeping down in place when your in the hammock.
  • 5 loops per side (lengthwise) to help you attach the underquilt to various brands/ makes of hammocks (attachments not included)
  • Includes stuff Sack and storage bag
  • Both Head and Foot Draft Baffles are standard on these Underquilts
  • Comes with a silnylon stuff sack.
    • Please store loosely when not in use (Pillow case or laundry bag – etc.)
    • Does include a storage bag
  • In the winter it is a good idea to use an Under Quilt Protector and a proper tarp to protect from the wind. The UQP can help prevent frost from building up inside your UQ (which instead layers along the UQP).

Features / Options:

  1. Temperature Ratings :
    • The ratings are a general comfort rating for the average person wearing a good base layer / fleece as well as other cold weather sleep system.
    • -17°C / 0°F : 22oz of down (more overstuff than standard 0°F UQ)
    • -25°C / -13°F : 26oz of down
    • -32°C / -31°F : 30oz of down
    • -40°C / -40°F : 34oz of down (New Custom build)
  2. Color Choices / Fabric: (to see individual colors scroll down)
    • 15D and 20D fabric available in a number of color choices
    • The 20D fabric is a bit more airtight so it will take a bit more time to loft up. If you are considering using both sides 20D, this will be a factor. The quilt is properly stuffed, just takes a bit more time to loft. Perhaps consider using only one side 20D
  3. Leg insulator
    • Standard feature As of Oct 26/21 
    • 3D insulation that attaches to the UQ near the legs to prevent air from entering and fills the gap that a difficult hang might encounter. It can be attached on either side for left lay or right lay users. It can be removed and left at home if it’s not needed for a particular outing. Filled with high power down.

Leg Insulator: 

FAQ: What makes these different than the other Toaster UQ’s?
The Extreme Winter series has a second draft collar, attachment points for the insulator and generally a bit more down than you would expect from an equivalent from a competitor. It’s not all overstuff, it’s larger baffling as well to get these ratings up. So for example the 0°F Extreme winter UQ (which is listed in both UQ selections) has more down, a second draft tube baffle, and the attachment points for the Cold Butt Syndrome Insulated Pad.

    Just received my Toaster Extreme Winter Under Quilt from James at LSOH. I have not been able to test it fully yet as its only October and its rated for -40 but I can comment on how impressed I am with the construction and how well thought out the suspension is. You can adjust it exactly how you want without squishing the down and loosing loft. I know its just an UC but it really is a thing of beauty. If you live in Canada and need an UQ for winter look no further, this is one killer Quilt
