Sleeping Bag Storage and Care


Storage 

Sleeping bags are filled with lofty materials to keep them in shape and effective in service.

If you store the sleeping bag without proper care and treat it as any regular quilt, the result wouldn’t be good.

Avoid compressing your sleeping bag like any other quilt. It will gradually decrease the quality of lofts and deteriorate the shape of the bag, resulting in poor insulation.  Use the storage sack that’s been provided with the package. They are specially made to retain the fluffiness of your bag.


Care

Here is what you should do if your sleeping bag is wet after a long trip. Air-dry the sleeping bag. Never store your wet bag in the stuff sack as it will create irreversible mold on them.

In case they get dirty, use warm water to spot clean them. It is wise not to use regular detergent as it can hamper the inner coatings of the sleeping bags.

Down VS Synthetic Sleeping Bags

Down or Synthetic Sleeping Bags? Let’s analyze this down based on two different factors.


Cost 

When it comes to cost, down materials are comparatively more expensive than synthetically insulated bags. Same size synthetic sleeping bags will cost you less than down bags.


Performance

Synthetic materials are thicker and bulkier than down materials. Sleeping bags made of synthetic materials will be 7 in a 10 when it comes to portability.

In this case, down bags wins the race. They weigh comparatively less than synthetic bags. With down material-made sleeping bags on your shoulders, you will be at ease while carrying them anywhere.

In my opinion, it is always better to spend a few bucks extra and have quality service than become a victim of a poor choice.


Buying Guide for the Best Budget Lightweight Sleeping Bag for Backpacking

In this segment, we’re going to discuss a quick guide about the best budget lightweight sleeping bag for backpacking


Right Temperature Rating

If you want a sleeping bag for a 3 season trip then you must be conscious about the temperature rating. Actually, the temperature rating isn’t the exact science. Here you have to consider some other factors that contribute to warmth such as clothing, sleeping pad, insulation, hydration, etc.

So better to choose a sleeping bag where you can adjust the temperature by organizing everything inside it.

The ISO and European Norm (EN) determined the standard temperature rating (including the bag temperature rating and comfort rating.) According to a survey, most cold sleeper come with an EN lower rating that is generally 10-15 degrees lower than the EN comfort rating. So, try to find the EN comfort rating in the bag because it is much more realistic and indicates how the bag will perform.


Sleeping Bags VS. Quilts

Mummy bags trap body heat inside whereas quilts maintain proper warmth to weight ratio to ensure you naturally feel warm.

Here’s the thing, there are different fan bases for sleeping bags and quilts. If you prefer quilts over sleeping bags, it’s completely fine. Quilts are better used above freezing temperature 32F. Where you can use sleeping bags for terribly cold weather and below-freezing temperatures.

In my opinion, quilts are more flexible and easy to use. You need to pay only a little attention to its maintenance and storage policy. They are perfect if the temperature is above 32 degrees; considering a non-snowy winter season. Below freezing point, sleeping bags are a must-have essential for survival.


Water-resistant

Surely you are going to have a miserable cold night if you have to spend a night in a wet sleeping bag. So, it is highly necessary to choose a waterproof sleeping bag. Make sure the outer shell of the bag is water-resistant. In that case, the synthetic insulation bags are more helpful because they can hold warmth better than down when it is in a wet condition.


Length and Width

Obviously, these facts are some of the major considerations because if the length and weight aren’t ideal for your body size the bag will never be comfortable for you. Must ensure you get some extra space to breathe freely. Check out the overall size before purchasing one.


Zipper Length

You will find different bags with different zipper lengths. Among them, we would suggest a bag with a full-length zipper because they let you open the bag completely for the ultimate ventilation. However, they are slightly heavier. If you want a lighter one then the better choice would be a half zipper bag. But keep in mind the bag won’t provide the high facilities.


Less Interior Space

Did you know, the sleeping bag doesn’t create warmth, instead it just holds the temperature that our body creates. It’s a way of trapping temperature. In that case, if the interior space of the sleeping bag is higher then it may create a bigger area for your body to warm up. That means it’s not highly effective. So, a bag with less Interior Space would be a better choice.


Price

We don’t want to join any argument by determining any particular price range. It’s because sleeping bags come with different features and facilities and also prices. You can get a qualified sleeping bag for just $50. Again, better products may cost over $300. However, just check out all the features before choosing one and ensure the price is worth the features.
