Performance Evaluation

Fabric Performance

Breathability The Nemo Disco 15 excels in breathability thanks to its 30D Nylon Taffeta lining. This material allows for efficient moisture wicking, ensuring you stay dry and comfortable throughout the night. The addition of Thermo Gills™ enhances breathability by providing adjustable ventilation. These gills can be opened to release excess heat without exposing you to cold drafts, making it easy to regulate your temperature as needed.

Waterproofing While not entirely waterproof, the Nemo Disco 15 offers commendable water resistance. The 30D Nylon Ripstop shell is treated with a Durable Water Repellent (DWR) finish, which helps to shed light moisture, such as dew or a brief drizzle. However, for heavy rain or extremely wet conditions, it’s advisable to use a bivy sack or ensure your tent provides adequate protection.

Durability Constructed from robust materials, the Nemo Disco 15 is designed to withstand the rigors of backpacking. The 30D Nylon Ripstop shell resists tears and abrasions, while the high-quality YKK zippers are built to endure frequent use without snagging or breaking. The overall build quality ensures that this sleeping bag can handle the demands of various outdoor environments over time.

Weather Resistance

The Nemo Disco 15 performs admirably across a range of weather conditions. During testing in the Pacific Northwest, it provided excellent insulation on cold nights, thanks to the 650-fill power Nikwax Hydrophobic Down. This down retains its loft and insulating properties even when exposed to damp conditions, a critical feature in areas with high humidity or frequent rain. The Blanket Fold™ feature offers an extra layer of warmth around the neck and face, which is particularly useful on windy nights.

Practical Features

Zippers The full-length, double-slider YKK zippers are a standout feature, allowing for easy entry and exit from the sleeping bag. They also enable versatile ventilation options, such as opening the bottom for foot venting on warmer nights.

Pockets The integrated pillow pocket is a thoughtful addition, allowing you to stuff a jacket or extra clothing to create a comfortable, stable pillow. Additionally, a small stash pocket near the top of the bag provides a convenient spot for keeping essentials like a headlamp, phone, or glasses within easy reach.

Adjustments for Comfort and Utility The Thermo Gills™ are not only great for temperature regulation but also add to the overall comfort by allowing fine-tuned adjustments based on personal preference and weather conditions. The Blanket Fold™ feature mimics the cozy feel of a comforter, adding an extra layer of warmth and comfort.

In summary, the Nemo Disco 15 offers outstanding performance across several critical areas, making it a reliable and versatile sleeping bag for three-season backpacking. Its combination of breathability, water resistance, durability, and practical features ensures that it meets the demands of various outdoor conditions while keeping the user comfortable and well-rested.

Fit and Comfort

Sizing and Fit

The Nemo Disco 15 is available in two sizes, Regular and Long, designed to accommodate different body types. The Regular size is suitable for individuals up to 6 feet tall, while the Long size is designed for those up to 6 feet 6 inches. This range ensures that most users can find a suitable fit. The sleeping bag’s unique spoon shape sets it apart from traditional mummy bags, providing extra room at the elbows and knees. This design allows for greater freedom of movement, making it an excellent choice for side sleepers or those who tend to shift positions during the night.

Comfort During Various Activities

Sleeping Positions The spoon shape of the Nemo Disco 15 significantly enhances comfort by allowing users to sleep in a variety of positions. Unlike traditional mummy bags that can feel restrictive, the Disco 15’s design offers ample space for side sleepers to bend their knees and move their arms freely. This flexibility ensures a more natural and restful sleep, which is crucial after a long day of hiking or backpacking.

Temperature Regulation One of the standout features contributing to comfort is the Thermo Gills™. These adjustable vents can be opened or closed to manage internal temperatures without letting in cold air. This feature is particularly useful for maintaining a comfortable sleeping environment across a range of temperatures. Whether you’re camping in cool mountain air or a warmer forest setting, the ability to fine-tune ventilation helps prevent overheating or getting too cold.

Additional Comfort Features The integrated pillow pocket is a thoughtful addition that enhances overall comfort. By stuffing the pocket with a jacket or extra clothing, you can create a makeshift pillow that stays in place, preventing any discomfort that might arise from a shifting pillow during the night. The Blanket Fold™ feature further adds to the coziness by mimicking the feel of a comforter, providing extra warmth around the neck and face.

Overall Comfort Overall, the Nemo Disco 15 excels in providing a comfortable sleep experience for various types of outdoor enthusiasts. The spacious design, combined with thoughtful features like the Thermo Gills™ and integrated pillow pocket, ensures that users can achieve a restful night’s sleep, regardless of their preferred sleeping position or the outdoor conditions.
