Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a Comfort rating and Lower Limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or "warm sleeper") comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.

Rated 5 out of 5 by from A great lightweight bag with excellent features I love this bag, I sleep warm and used this on a recent trip to the High Sierra where were were hit with rain, hail and snow as well as sleeping on 12 feet of snowpack at 10,000ft a couple evenings in below freezing temps. The q-shield technology really makes its mark when combined with the Ghost UL tent line where condensation can sometimes be an issue. This bag makes up for the minor tent issue by keeping its warmth and drying out lightning quick in the mornings with just a little sun or wind. As a photographer people always ask how I get my batteries to last when camping in winter conditions, it is a constant battle to keep the batteries as warm as possible, so I have always had to sleep with them in my pockets. With the genius interior design of the bag there are not one, not two, but THREE pockets to store small items close to your body's warmth. I was able to store all the electronics overnight and keep them working longer than expected in such cold conditions. Great work MHW. I highly recommend this bag.
