The all-weather reliability of synthetic insulation and the lightweight, compressible performance of down combine in the Sierra Designs Zissou DriDown 23 Degree sleeping bag with its water-resistant DriDown 700 fill power insulation.



The all-weather reliability of synthetic insulation and the lightweight, compressible performance of down combine in the Sierra Designs Zissou DriDown 23 Degree sleeping bag with its water-resistant DriDown 700 fill power insulation.

Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of goose down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet; but DriDown performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 7 times longer and dries 33% faster, should it become wet, than untreated down bags. Perhaps most impressively, this allows the insulation to retain 98% of its loft which translates into maintained warmth that untreated down bags simply cannot achieve.

The Zissou DriDown 23 Degree’s 30D Polyester Micro-Ripstop shell fabric further protects the bag’s interior and, along with a streamlined mummy shape, maintains the overall lightweight construction. An ergonomic hood mirrors the design of insulated outerwear jackets and helps reduce heat loss by keeping your head warm and comfortable. A fully insulated draft tube behind the snag-free zipper keeps cold air from reaching the inside of the sleeping bag and a 60", two-way zipper allows you to vent the bottom of the bag on warmer nights. Other features like a drawcord closure at the collar and an ergonomic foot box provide a comfortable night of sleep.

The Sierra Designs Zissou DriDown 23 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") lengths. A stuff sack and storage sack are included.

Lightweight and compressible sleeping bag
Reviewed by Felix CW - February 8, 2016

Likes: -Very easy to pack into a 10 stuff sack
-While the degree rating is 34 with a lower comfort zone of 23, I found the bag to be very warm in the 5 days that I slept in it with my OR Alpine Bivy. For cold sleepers, this bag would still work great with the use of layering inside the bag
-Interior is very soft against the skin
-Small pocket on the upper near the hood is the perfect size for a watch or small headlamp.
-Colors are great, with green and blue contrast
-Dridown material is a big plus for backpacking in wet climates

Dislikes: -Nothing
