Combining moisture-resistant down insulation, an innovative zipper design and a full suite of features for comfort and ease of use, the Sine 35 / EN 29 Sleeping Bag from Kelty is a versatile bag for serious camping and backpacking.

EN tested for comfort down to 29°F, the Sine features 800 fill power DriDown insulation, which uses down feathers treated with a hydrophobic coating that preserves the down's loft even if the bag is damp from condensation. Down is as light as it is effective, keeping the Sine 35's weight down to 2.1 pounds. It comfortably accommodates sleepers up to 6 feet 6 inches tall.

The bag's unusual angled zipper opens with a natural motion of the arm, and because it has pulls at both ends, can be used to ventilate at the head or midsection. An anti-snag draft tube prevents heat from leaking out through the zipper, and a second angled zipper near the feet offers more ventilating options.

The handy built-in pillow pocket can be stuffed with a fleece or other soft goods for a comfortable head rest. The bag comes with a stuff sack for transport and a mesh bag for storage.
