Sierra Designs Rissou 23 review

The Sierra Designs Zissou 23 resting bag is the bag many people have been using consistently for the previous season and 50 percent. I selected this up at a significantly lower price at REI without doing much analysis, and since, have gotten to be able to know the bag very well.

The primary function that drawn me to the bag was a mixture of heat and body weight. I seem to run hot, so a bag with a 23 ranking is excellent for me down to around 10 levels. I used this bag in Peru last season, and on the Ausangate travel, I invested a few evenings in individual numbers without being too unpleasant. I’d say the perfect variety for me on this bag is 10 levels up to about 65 levels.

I used this bag on a few summer time overnights, and even unzipped, was perspiration quite a bit. The load for this bag is also excellent at 2 lbs. They fit perfectly into my package without with a weight of me down.
