Migliaccio & Rathod LLP is investigating whether Zenbivy sleeping bags, quilts, and sleep systems may use temperature ratings that consumers could reasonably understand as comparable to standardized EN or ISO ratings even though Zenbivy uses its own rating methodology.
Temperature ratings are important when consumers choose sleeping bags and quilts for cold-weather camping. Shoppers may compare one company’s advertised “Comfort Rating” or “Limit Rating” directly against similar numbers from competing products.
Zenbivy has stated that it stopped obtaining standardized EN temperature ratings in 2021 and instead determines its current temperature ratings using its own methodology, including comparisons based on insulation loft. At the same time, Zenbivy continues to use terms such as “Comfort Rating” and “Limit Rating,” terminology that consumers may also encounter on products tested under standardized EN or ISO methods.
Why This May Matter
A consumer comparing a Zenbivy product labeled with a 25°F comfort rating against another sleeping bag with an ISO-tested 25°F comfort rating may reasonably assume the two numbers were determined in a similar way.
If the underlying testing methods are different, consumers may not be receiving the apples-to-apples comparison they expect when selecting gear for cold-weather use.
Migliaccio & Rathod is investigating whether Zenbivy clearly explains its rating methodology to consumers and whether shoppers understand how Zenbivy’s temperature ratings differ from standardized EN or ISO ratings.
Consumers May Have Encountered:
- Zenbivy products advertised with a specific “Comfort Rating” or “Limit Rating”;
- marketing that appeared comparable to standardized sleeping-bag temperature ratings;
- purchasing a Zenbivy product based on its advertised temperature rating;
- comparing Zenbivy’s rating directly with EN- or ISO-rated competing products;
- not realizing at the time of purchase that Zenbivy used its own rating methodology; and
- experiencing substantially less warmth than expected from the advertised temperature rating.
Potential Claims May Include:
- false or misleading advertising;
- failure to clearly disclose the temperature-rating methodology;
- deceptive trade practices;
- breach of express warranty; and
- damages associated with paying for thermal performance different from what consumers reasonably expected.
Signs You May Be Affected:
- You purchased a Zenbivy Sleeping bed, quilt, sleeping bag, or sleep system;
- the advertised Comfort or Limit temperature influenced your purchase;
- you believed Zenbivy Sleeping’s rating was directly comparable to an EN or ISO rating;
- you compared the rating with temperature ratings from other manufacturers;
- you did not know Zenbivy Sleeping used its own rating methodology; or
- the product performed substantially colder than you expected from its advertised rating.
