If you want the perfect blend of quality, comfort and warmth-to-weight, it’s tough to beat the Feathered Friends sleeping bag. The small Seattle-based company is a leader in the field of premium down products and produces all kinds of products within the Pacific Northwest. The climbers make a point of stopping in regularly prior to departing for Mt. Rainier Alaska or other remote destinations such as the Himalaya and the Himalaya, and it’s worth the trip when you’re located in Seattle (their location is directly opposite their flagship, the REI main store). It also has a direct-to consumer model, Feathered Friends sleeping bags and other products from down are extremely well-made and reasonably priced for the quality you will receive.
To be used in all three seasons for three seasons, the Hummingbird YF is our favorite sleeping bag that is available. It’s filled with 14 ounces filled with 900-fill goose down, and has a waterproof 20-denier Pertex Quantum shell, and weighs in at 1 pound and 10 pounds for the model with a 20-degree angle (in our experiences, Feathered Friends bags run much warmer than their advertised ratings). Although it’s a substantial investment at $479 but the Hummingbird is designed to last. Even after nearly 10 years of use it shows no signs of wear and is still as warm as it was on the day we purchased it. Also, when compared against the renowned Western Mountaineering UltraLite below (also with a rating of 20°F) it’s heavier and considerably less expensive. If you’re looking to reduce the weight of their backpacks, Feathered Friends also makes the Hummingbird UltraLite (1 1 lb. 8 oz.) with a lighter 10 denier shell, plus the highest quality 950-fill down available for $569.
