Solid bag.

  • Familiarity: I've used it once or twice and have initial impressions

I purchased this bag to replace my 3-year-old Kelty Cosmic Down 0 which I loved. This bag was comparable in price, but slightly lighter weight, more water repellant, and had more fill. So far, I really like the bag but I have not had a chance to test it in freezing conditions yet. It does not seem to be as warm as my Kelty was, and does not have as high of a loft to it. But it is still very cozy, warm, and the DriDown has been tested and performed excellently!

Best bag I've owned!

  • Familiarity: I've put it through the wringer

Love this thing. Bought with intended use being winter/spring ski camping and got the long for the extra space for drying gear (I'm ~6'). So much room in there; with liners at my feet the hood still completely covers my head, and I can roll from side to side without getting claustrophobic. This bag is comfy and toasty; coldest outside temps were around 10*F and I slept like a rock. Have woke with some serious condensation in the tent, the treated down still stays lofted and warm; dries quickly in the sun. The low weight is wonderful, too; same weight as the cheap summer bag I bought before this. Love the color, too; things don't get lost in the bright green.

I always look forward to a night spent in my Zissou, no matter where or when.

Dry and Warm

  • Familiarity: I've put it through the wringer

I got this bag last winter and I am loving it! I took it on a hut trip to the Tushar Mountains in Utah last February and it kept me super warm and allowed me to regulate my temp really well as the wood stove burned hot and then died off I was able to stay comfortable.

The bag was great in the desert this spring for the same reasons, it keeps me warm when the temp droped steep at night and then was able to breath enough that I wasn't sweating when the sun came up.

The bag also has a nice cut that gives you enough room for shoulders, chest and arms.

I am 5'8" and went with a regular and the bag has tons of room bellow my feet I bet it could easily fit a 6' guy.

All and all totally stoked on this bag. Finally I have a bag that can handle all the winter and spring adventures I love.

My big blue fortress

This bag has been with me everywhere, which is exactly why I love it. It withstood rain and a soggy tent on the Olympic Peninsula, sub-freezing temps on a windswept ridge near Mt. Rainier , and was my bed for 3 months this summer in desolation wilderness. On a sizing note, the bag runs a little roomy, I'm 6'3" 155lbs and I got a long which I love but still have another 3-5 inches of space in the foot box. I wouldn't trade this bag for anything, a little pricey but so so worth it!

Is the draft tube on the top or bottom? ...

Is the draft tube on the top or bottom? I have found that a top draft tube "falls" over the zipper, thus covering it. Bottom draft tube falls below zipper - much less effective.
