If you weren’t aware there was an international standard for the temperature rating of sleeping bags, that’s okay, neither were we! With the ISO 23537:2016 replacing the outgoing European standard, Blackwolf has revised its current range of sleeping bags to make it easier for customers to understand and compare apples with apples when making their purchase. Each sleeping bag displays a chart showing the “comfort, limit and extreme” temperature ratings for that bag. Blackwolf’s range of performance and camping sleeping bags are available in a number of different sizes with clearly-defined temperature ratings ranging between -10 and 15 degrees.
