Our "Full Zip" sleeping bag has a #5 two way zipper that extends to the toe of the bag for superior venting. The bottom end of the zipper can be opened to kick your feet out, or flip the bag around and wear it like a cape in camp on a cold morning. This bag includes a draft tube covering the zipper. For maximum warmth lay on the zipper to keep it insulated under you, or turn it to the side or top for convenience on warmer nights.

The bags are made with premium 900 fill power white European goose down and some of the lightest nylon shell materials available. Our down is ethically sourced straight from the producer. Our down is tested with International Down and Feather Association (IDFB) Lorch standards, and is comparable to 950 fill power down tested in the US.

The longer two-way zipper and draft tube contribute about 3.2 ounces (91 grams) to the total weight. For a slightly lighter option compare our 3/4th zip 'Classic' sleeping bag, or our 'Solo Quilt'.


Goose down works by creating tiny air pockets which act as a thermal barrier. Generally speaking, the more loft a bag has (the thicker the insulation) the more air it traps and the warmer it is. It is very important that the down stays where you want it rather than shifting around or clumping up, creating thin cold spots. Our bag has narrow, relatively short chambers so that the down has less room to migrate. It has vertical chambers at the upper body to prevent the down from being pulled to the sides by gravity as you shift around at night. There are no sewn-through spots except the zipper which is covered by a draft tube.
