Condensation might not be at the front of your mind when planning for a cold weather camping trip, but a little bit of moisture can seriously dampen the fun you should be having outdoors. If it isn’t snowing, the frost on your tent melts when the sun comes up or if it is snowing and it piles up and soaks through the tent. Either way, you could end up with a soaked sleeping bag and that has the potential to ruin a trip. Don’t let that happen to you! Thankfully, Sierra Designs has introduced the DriDown line of bags including the Zissou 0 sleeping bag.

What sets this bag apart from the competition is that it is filled with 600-fill DriDown insulation. That means each individual feather in the bag is coated with a molecular level polymer to create a hydrophobic finish. Simply put, the down inside the bag is water-resistant. It stays dry longer than regular down, puffs up better and if it does happen to get wet, it doesn’t take as long to dry out. That means you will stay warmer for a longer period of time in this space-age, yet down-to-earth bag.

The fill weight is a mere 33 ounces and the bag features an ergonomic footbox and hood to keep you snug and comfortable. It comes with stuff and storage sacks and we offer it in regular and long sizes so there’s definitely a version for you! The Zissou 0 has been getting a lot of positive press lately and was recently featured in a cold weather camping blog on the Huffington Post.
