Back in 2016, we took notice of a new sleeping bag design called NoZipp, which was built around two clever features. First, a pair of overlapping front flaps that were inspired by the construction of a double-breasted suit coat. These sealed in heat and allowed the bag to be configured in an enclosed mummy mode, a more spacious roomy mode, or an open mode that allowed unrestricted airflow to the upper body. Second, the original NoZipp used a series of magnets to close the bag, eliminating snag-prone zippers.

After its launch on Kickstarter, the NoZipp was an immediate success. Within 8 days of its launch, it reached its $10,000 funding goal and went into production. Since then, it has remained a popular alternative to the traditional sleeping bag, but the company has recently announced the development of a secondary version: the NoZipp UltraLight (UL).

Weighing in at 30 ounces, the NoZipp UL is said to be 20% lighter than the original version, and retains the overlapping baffles that can be configured in the same three modes. However, magnets are naturally heavy, so the UltraLight replaces them with a series of button toggles. These are lighter than magnets or an ordinary zipper.

This bag has not yet entered full production or undergone EN temperature testing, but NoZipp says it will be rated at a lower limit of approximately 20°F (-7°C). Pricing will begin at $259 for “Early Bird” Kickstarter supporters, and will eventually be $349 once the production run is fully-funded. NoZipp says this price/weight/warmth value is industry-leading, and provided the following chart comparing its the UL's specs to competitors:

The NoZipp UltraLight will become available for pre-sale once the Kickstarter campaign begins next month — September 19th, to be exact. For more information, go to NoZipp.com or follow the company's Facebook page.
