Finding the Best Ultralight Sleeping Bag

When it comes to ultralight sleeping sacks, there are a number of options to choose from. There are mummy-shaped bags, ones with closed foot boxes and ones with hoods and others without hoods. Some bags are insulated with synthetic fibers, some with duck down and still others with goose down. How is a camper supposed to choose from all of these different options? Well, the simple answer is by taking all of the features into consideration and weighing them against their particular needs. Below are some things to look for before purchasing an ultralight bag.

The Shape of the Bag

There are basically two different shapes to consider when it comes to ultralight sacks and these two shapes are mummy and quilt shaped bags. Most modern 3-season bags manufactured nowadays are mummy bags and there’s a good reason for that. That’s because the ones with hoods can be cinched around the head, particularly the face, and are usually warmer around the feet area. This leaves less air inside the bag to heat, which means that it heats faster thanks to the person’s body heat. It also makes them the warmest bags available. However, it also means that these bags are more constrictive and some people may have a problem with not having much room to move around in.

Quilt bags are not as constrictive as mummy bags. These bags save weight by not having an underside to sleep on. It doesn’t have this part of the bag because it’s believed that laying on top of the insulation limits its thermal properties, so why have an underside at all? However, this also means that they aren’t as warm as mummy bags and shouldn’t be used in extremely cold conditions. Another problem with these quilts is that the camper will usually have to carry a sleeping pad with their bag as well to keep the ground from acting like a heat-sink and sapping all of the heat out of the person. And the added weight of a pad completely negates not having a bottom portion of the bag.

Temperatures Ratings

Every bag comes with a rating that tells you the temperature range of the bag. This limit will tell you what temperature the bag will hold its thermal capacities and not necessarily the temperature that’s comfortable. Which is why the camper should choose a bag that’s warmer than what they think they’ll need. Some bags conforming to the EN 13537 standard show the consumer three different temperature ranges. One is the limit of the bag, one is the temperature at which the sleeper can sleep comfortably and one is the extreme limit, which is the maximum limit the bag will protect the sleeper.

Insulation Materials

While sleeping bags with synthetic fill might be fine for most camping trips, users who want an ultralight bag will want to choose one that’s made with bird down – either duck down or goose down. That’s because down insulates better than synthetic insulators and has a better thermal to weight ratio. Which makes it the choice in cold, dry environments. However, if the camper or hiker is going to travel in wetter conditions, then they probably aren’t going to want to go with down. That’s because it doesn’t dry quickly and loses its thermal properties when wet. Therefore, in those circumstances, it’s best to choose a synthetic insulator or a down that’s been treated with a DWR (durable water resistance) coating.

Zipper Tubes

One of the features that increase the warmth of a bag without increasing its weight is zipper tubes. These tubes prevent warm air trapped in the bag from escaping through the zipper. Zipper tubes can really help keep the sleeper warm and it adds almost nothing to the overall total weight of the bag.

Compression Sacks

Another thing that needs to be considered when purchasing an ultralight bag is the compression sack. Most of the bags sold today have these sacks, but if a particular model doesn’t come with one, then the consumer should consider purchasing an after-market one. While compression sacks don’t decrease the weight of the bag, they do allow the bags to be stored in a way that’s convenient to handle.

In Conclusion

Choosing an ultralight bag for sleeping doesn’t have to be difficult, as can be seen from the above article. If a little bit of thought is placed into the construction, shape, and insulation of the bag and that’s matched up against the sleeper’s needs, then it doesn’t have to be hard at all.
