Its important to understand that a sleeping bag does not warm you up its job is to retain the heat that your body generates, preventing you from getting cold. Our ratings describe how well a sleeping bag retains heat when the air exterior to the bag is at a certain temperature.Because all of our bodies are different, what one person needs for a good nights sleep is not necessarily the same as the next. This means that it is difficult to quantify exactly how warm a sleeping bag is and as such, any rating should be treated as a guide. At Rab, we use the European EN13537 standard to rate the majority of our sleeping bags.Rab Sleep LimitWe have created the Rab Sleep Limit to supplement the standard EN13537 results. It is not an emergency metric in the same way as the Extreme Rating rather what we believe the bags usable limit to be.The Rab sleep limit is what we believe the sensible limit of the bag to be from past experience and feedback from our athletes.Learn more about Rab Sleeping Bag Sleep Limits ?https://rab.equipment/guides/sleeping-bagsShop Sleeping Bags ?? // https://rab.equipment/sleeping-bags/sleeping-bags#WeAreRab #TheMountainPeople #RabSleepLimits
