MUMMY BAG

TEMPERATURE RATING

Summer, winter, or all year round, the temperature rating on your sleeping bag is incredibly important. If a bag is rated for 30° that means that the average person will stay comfortable in temperatures as low as 30°. But keep in mind that everyone is a little bit different, so if you run hot or cold you might want to look at a lower or higher temperature bag that fits your specific needs. For example, if you run cold you might want a winter bag all year round. Summer bags are usually rated at 32° F or higher, 3-Season bags are 10° - 32° F and winter bags are 10° or lower. When picking out your sleeping bag be sure to go with one that’s rated for temperatures around 10° or 15° degrees cooler than you’re expecting. There’s nothing worse than being cold all night and it’s incredibly easy to just unzip your sleeping bag for extra ventilation if the weather ends up being hotter than expected.

EN TEMPERATURE RATING

EN TEMPERATURE RATING
The USA doesn’t have a standardized temperature rating system, this means that a 30° rated bag from one company might not be as warm as a 30° rated bag from a different company. This is where Europe’s EN Temperature Rating System (or the EN 13537) makes things way easier. The EN Temperature Rating is used by a lot of outdoor companies and bases its temperature ratings on standardized tests. If you have two sleeping bags that have both been rated at 30° by the EN Temperature Rating System, you’ll know that both bags will end up functioning the same in 30°conditions.

INSULATION CONT...

DOWN INSULATION
Down is a warm layer of fine feathers that grow underneath the tougher feathers on duck and geese. These soft feathers are nature’s way of making sure that the duck stays warm by trapping air in, and reducing heat loss to create a barrier against the cold. This same process is what happens in your down sleeping bag.



Down is by far the warmest insulator on the market and comes in a wide variety of qualities and prices. It’s also a favorite of mountaineers and backpackers because of its lightweight construction and awesome compression. When looking at sleeping bag options you’ve probably noticed that each one has its own fill rating ranging from 450 – 900 fill. These fill numbers measure how many cubic inches one ounce of down can fill. The higher the fill number, the better the quality of the down in your bag. An 850-fill down sleeping bag will have more loft and be lighter weight than the same bag would with a lower fill down.
