- With a European Norm (EN) lower-limit rating of 15°F, the Blue Kazoo is a versatile bag for 3-season backpacking and climbing adventures
- Lofty 650-fill-power ProDown™ natural goose down insulation keeps the overall weight of the bag down while providing great warmth
- ProDown™ is enhanced with a hydrophobic finish that improves warmth by allowing it to dry faster and repel moisture up to 10x longer than untreated
- Trapezoidal side baffles trap insulation and prevent it from shifting to ensure a constant baffle volume and help prevent cold spots
- Ergonomically shaped Climashield® Prism synthetic insulation pads on the bottom create a compression-resistant, insulating buffer between you and the ground
- Anti-compression pads made from Heatseeker™ Eco synthetic insulation are sewn into high-pressure areas that contact the ground to create an insulating buffer
- Shaped hood and down-insulated draft collar hold in warmth
- Insulated draft tube backs the zipper to prevent warm air from escaping; antisnag tape keeps the zipper from catching on the draft tube
- Full-length, 2-way zipper lets you make adjustments for ventilation
- Footbox allows natural foot movement while also eliminating excess lateral space so you stay warm and comfortable all night long
- Pad loops give you a way to attach the sleeping bag to your sleeping pad (sleeping pad and attachment straps not included)
- Comes with a compression stuff sack and a storage sack
- European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags

Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
