Product Description

When wet, regular down plumes collapse, reducing loft and insulatory efficiency. DriDown's water tolerance far exceeds that of regular down, staying dry 7-times longer in the presence of natural body moisture, humidity, rain, and snow, offering superior loft and thermal efficiency for a warmer, more comfortable nights sleep. While in the outdoors, in an 80-Percent relative humidity environment, an untreated 15oF down sleeping bag loses up to 30-Percent of it's loft over an 8 hour window. This is the essentially the difference between a 15oF and a 300F rated sleeping bag. DriDown sleeping bags retain 98-Percent of it's loft over the same time period. This loss in traditional down bags is most impactful when the overnight temps dip the lowest, in the early morning hours, when you need the highest thermal benefit out of your bag. DriDown maintains it's loft and thermal performance, and will continue to perform at this level over a sustained length of days in the field by staying dry seven times longer and drying 33-Percent faster than traditional down bags. Sierra Designs uses ASTM-certified lofting tests, environmental chambers to simulate humid conditions, and tests to determine drying times. Sierra Designs has also developed proprietary testing to evaluate DriDown performance in extreme conditions. Field testing confirms that it outperforms regular down in every situation. Other features on the Zissou include: *Ergonomic Hood(tm) is shaped to cradle the head comfortably without compressing the insulation. Mini baffle of insulation below the draw cord allows snugging of the cord without feeling the cord. *Keeps cold air out by utilizing a draft collar with draw cord and zipper draft tube.

I slept out under my old Kelty Noah's 12 tarp last night. I had washed the tarp after it's last trip out and did not treat it with more waterproofing, so the tarp leaked badly. It rained hard 3-4 times in the night and I had dripping water all over the bag. The water was dripping on my head and neck, until I pulled the bag up over myself. The temperature was in the low 40's and I was very comfortable.

The bag beaded up water well and was at least 85% lofted in the morning, even though it was quite damp on the outside of the bag. There was no moisture on the inside of the bag and the lining inside the bag was dry and warm against my skin.

I was testing out the bag in the yard at my home. I do think it may have been a problem for the second night, if I had been on a trail somewhere, and just stuffed this wet bag in a stuff sack and tried to use it a second night, unless I had time to dry the bag during the day.

The bottom line is this. My tarp leaked and I slept warm, dry and very comfortable.

Very well built bag. Compresses well. Is very comfortable to sleep in. I recommend this bag to others.
