Sierra Designs Nitro Quilt 35 Degree

A lightweight alternative to a warm-weather sleeping bag, the Sierra Designs Nitro Quilt 35 Degree is open on one side in order to fully utilize your sleeping pad for under-body insulation and padding. While not for everyone, the innovative design saves weight and provides versatility.

The quilt is insulated with 800-fill DriDown water-resistant insulation. 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 15D nylon ripstop shell further protects the insulation from the elements.

Insulated interior hand pockets in the corners help you wrap the quilt around your body for greater warmth.

With a trail weight of just 1 pound, 4 ounces, the Sierra Designs Nitro Quilt 35 Degree fits individuals up to 6’ 3". A stuff sack and storage sack are included.
