Commentary on Sleeping Bag Rating Specifications (2004)

This commentary discusses ASTM F1720 for evaluating sleeping bag temperature ratings and its limitations. We consider new ideas for improving the method to give industry and its consumers more reasonable data to make better informed decisions about sleeping bag manufacturing, buying choice, and use. Also discussed is the uncooperative relationship that exists between manufacturers and end users and calls for manufacturer responsibility in disclosing and reporting accurate and ethical rating data.
