    The Zissou 23°F sleeping bag features the new Sierra Designs DriDown™ finish for down insulation. It resists water and dries fast for backpacking in chilly, wet weather!

    • Regular down takes on water and is very difficult to dry; DriDown proprietary process treats each individual duck down plume with a hydrophobic finish
    • With the duck down now resistant to water, the insulation maintains its loft and stays dry 7 times longer than untreated down
    • It also performs better in high humidity than regular down and, in case it accidentally gets wet, it will dry out faster, too
    • Lightweight yet durable 30-denier micro-ripstop polyester shell and comfortable, moisture-wicking polyester lining warm up fast
    • Baffle construction keeps down from migrating, eliminating cold spots
    • Full-length 2-way, double sliding zipper allows easy venting; locking slider is backed by wide, antisnag binding tape
    • Snag-free zipper tracks prevent the dreaded stuck zipper by creating a barrier between the lining and the zipper track
    • Fully insulated draft tube backing the zipper keeps body heat in and cold air out
    • Ergonomic, nonrestrictive hood cradles your head in warmth; hood features differentiated drawcords that make fit adjustments easy, even in the dark
    • Roomy, ergonomically shaped footbox enhances comfort and warmth of feet
    • Sierra Designs Zissou 23°F comes with stuff sack and storage bag
    • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags

    Sierra Designs Zissou 23 Sleeping Bagis rated3.92out of5by25.
    Rated3out of5byfromnot as ratedThis bag is best for warm weather, well above freezing. At around 30 degrees using an insulated pad and thermal underwear it did NOT keep me warm. I would change the rating to 40 degrees at best.

    Rated3out of5byfromLightweight, small, No where NEAR 23 degHaving spent MANY nights snow camping, etc.. including Denali twice... I have a good feel for what a bag should be. We now live in GA and just don't need a 0 bag. So 23 should be fine right? Nope.. I normally sleep warm, first night it was 30 degrees.. Woke up serveral times, each time to add a layer.. when I was done, I had expedition weight top and bottoms, lightweight underneath on top, heavy weight (yes they were dry) socks WITH liners, fleece top, was wearing a hat, Inside a bivy sack, in a tent... on a Big Agnes Q-Core insulated pad.... and I froze.... Was going to return it. but decided to keep it for its light weight and it packs very small in a compression sack. Mine doesn't look anything like the picture.. Not near as Puffy, etc... So will use it as a summer, borderline three season bag, for backpacking.... but would not recommend at all for cold conditions.

    Rated4out of5byfromGreat lightweight bag for warmer nightsDisclaimer: I exchanged this product before proper field test. Only tested in my house one night at about 55 degrees f. The bag was incredibly comfortable. Extremely light and packs down super small despite how roomy the bag actually is. I'm 6'4" 175lbs and had room to spare in the long version. Plus has a water resistant down. The reason I returned it is because I didn't think it would fit my needs camping pre spring in the northwest. One downside was there was a very low amount of down in the baffles and I could see how cold spots might develop. Also the zipper snagged a bit. All in all, if I was looking for more of a summer bag, I would definitely buy this bag. I'm leaning more towards the 12 now but currently testing out the Kelty SB 20.

    Rated5out of5byfromGreat bagGreat sleeping bag used in Blue Ridge Mountains. 15-30mph wind gust temperature droped into the teens. I slept great in this bag for a while. Woke up about 3am cold. I found the the temperature rating to be extremely accurate. 23 degrees means 23 degrees and no less. But I had no problems sleeping until it dropped below 20 then it was two pairs of long underwear and socks and a chilly few hours.

    Rated4out of5byfromGreat bag with a few shortfalls.Many great features. Nice weight and condensed size. Took this bag backpacking for 3 days. My only two problems with the bag are: 1) Bag israted at 20 degrees yet I was cold my first night in the bag waking up several times in 35 degree weather 2)Mummy style bag is to restrictive in the legs area . I could not sleep with one foot under my other knee as I usually do. Just a minor comfort thing.

    Rated2out of5byfromLight but coldI wanted a smaller bag so I could take a smaller pack for weekend backpacking trips. I know a number of people who own this bag and highly rate it so I took the plunge and bought one. Even in the large size the packed size and weight were impressive. The first use was a night with temperatures only down to around 40 degrees with an insulated air pad and I was cold to the point I had to put on a fleece jacket so there is no way this is 23 degree bag. I always look after my bags and store them loosely and shook the bag out about 3 hours before bedtime so it had lofted as much as it was going to. Maybe I just got a bad one? However I returned it and got a much cheaper Kelty bag that far exceeded my expectations. 8oz heavier but very comfortable even in colder conditions.

    Rated4out of5byfromPerfect bag for the tripI used this on a backpacking trip in the Red River Gorge. It was a wet drip and my bag performed like new the whole time. It is light and compressed very well. It even felt a little roomier than most bags that I've used. The temp got down to around 33 F and I was hot with pants and a t-shirt. I'm anxious to test it out in the "real" cold.

    Rated2out of5byfromTemps in the mid 20's and I FROZE!Temps only got down to 25, yet with an insulated mat, a blanket, two layers of clothing, and a dog, I still froze. Plus, I found feathers stuck in my blanket. Also, could see where there wasn't down in areas (this is AFTER shaking it like crazy). This bag would be fine for summer camping, but it is definitely NOT 3 season, unless you are in a warm climate for those 3 seasons.
