Delivering all-weather reliability, lightweight packability, and a number of comfort features, the Sierra Designs Zissou 35 Degree sleeping bag is a high performance option for warm-weather backpacking or camping.
The bag is insulated with 650-fill DriDown. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of 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 longer and dries faster, should it become wet, than untreated down. 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. A 20D polyester ripstop shell further protects the insulation from the elements.
The bag's baffled, relaxed mummy shape adds to thermal efficiency. An ergonomic hood helps reduce heat loss by keeping your head warm and comfortable. Baffled 5" sidewalls give the bag depth to maximize the feeling of livability while retaining warmth. A unique zipperless, self-sealing foot vent allows you to extend your feet out of the bottom of the bag in balmy weather but effectively retain heat when temperatures require it.
The Sierra Designs Zissou 35 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.
- Integrated trapazoidal shaped comforter
