Marmot Phase 30 Degree Sleeping Bag

Weighing just a few ounces over a pound, the high-performance Marmot Phase 30 Degree sleeping bag offers lightweight warmth and compressibility for summer or mild-weather backpacking.

The bag is insulated with certified 850+ fill power goose down. Fill power measures the loft or "fluffiness" of down insulation and Marmot goes to great lengths to guarantee certification with a battery of in-house and external verifications. Renowned for their efficiency in retaining heat and compressible properties, down fibers 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 traditional weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet. Not so on the Phase, which is protected with Marmot's Down Defender water-repellent treatment that allows the down to stay drier longer than untreated down in damp conditions. It also maintains significantly more loft and dries faster than untreated down. Pertex Quantum 10D nylon ripstop shell fabrics help to protect the insulation while keeping weight to a minimum.

Curved horizontal baffles keep insulation from migrating, reducing "dead spots" and ensuring that you experience consistent warmth. An anatomical footbox provides comfortable space for your feet and focuses additional insulation in a spot that is vulnerable to losing warmth. Other features include a contoured, ergonomic hood, a full-length two-way zipper that offers a venting option, and anti-snag zipper construction.

The Marmot Phase 30 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") lengths.
