As a team that is passionate about outdoor life, we understand what makes superlative outdoor equipment no matter the camping style or chosen adventure. We also know that no matter how good our materials or the designs we create, it is hard to make an informed choice when purchasing without a way to compare performance.
Well, we want to make sure you can purchase one of our sleeping bags in confidence and that’s why we test our adult sleeping bags to EN ISO 23537-1.
This is your reliable guide to a sleeping bag’s performance. No matter the brand or model, if a sleeping bag complies to the latest official European Standard it has been subjected to officially recognised industry tests to obtain an accurate temperature rating.
It is an expensive and resource-intensive process. To obtain a Standard rating for each model, we send a sample sleeping bag to an official independent test facility. Here, a computer-controlled thermal mannequin is used to determine the sleeping bag’s temperature limits. The heated mannequin, which is standard adult size, is placed inside the sample sleeping bag in a temperature- controlled climate chamber. Tests are carried out to obtain specific measurements that include heat build-up, sustained temperatures, temperature loss and rate of loss. The results create the recommended temperature limits that appear for each of our sleeping bag models.
