Lightweight Sleeping Bag

People who camp outdoors are the ones who would know the importance of a lightweight sleeping bag. Many people carry a huge pile of comforters for camping but carrying such volume is not only tedious but also ridiculous. While all the other items required for camping serve various purpose, the main purpose of a sleeping bag is to provide comfort. Choosing a sleeping bag requires some amount of knowledge as there are various types of bags that are designed for different purposes. But, in general, any sleeping bag should provide the warmth and comfort but should also be manageable in terms of size and weight.

Why lightweight sleeping bag UK is the most preferred?

Camping, especially recreational camping was first popularized in UK on the banks of river Thames. In the 1880s, the camping equipment were heavy and it was tough to carry them. But with the evolving technology, all materials required for camping and outdoor activities have become more compact.

The most comfortable and cosy sleeping bags usually takes a lot of space in the backpacks. But there are also lightweight sleeping bags in the market that are not only friendly on the backpack but also provide the warmth at night. While buying a lightweight sleeping bag UK, it is important to consider the season and temperature rating of the bag. Not all sleeping bags are designed for all outside conditions. The Season rating is explained as follows:

  • A season 1 bag is designed for summer months or while camping in tropical/hot countries.
  • Season 2 and season 3 bags are designed for use in spring and autumn.
  • A Season 4 bag is designed for use in cold/winter season.
  • A Season 5 bag is used for mountaineers and expeditions where it is extreme cold.

The temperature rating is listed with comfort ratings and extreme rating and are related. While the comfort rating denotes the temperature in which one feels comfortable and below which they will feel the cold, the extreme rating is the cut-off temperature at which the bags protects the user against extreme conditions like hypothermia.

The other aspect for choosing a lightweight sleeping bag is the type of insulation material used. There are two types of materials used – Down and synthetic. Down is the best material as it would last for a longer time and provides the necessary warmth than the synthetic ones. But the advantage of synthetic insulation is that it keeps the user dry.

Lightweight sleeping bags can also be chosen based on the different shapes available – Rectangle, Mummy, Semi-Rectangular, Bed-style, Quilt and Integrated Bags and Pads. They are also available specifically for women and kids.

How to Select the Warmest Lightweight Sleeping Bag?

There are so many general-purpose sleeping bags available in the market that can be used during the warmer months of the year. But the warmest lightweight sleeping bags are usually sought by people who are planning to spend a large amount of time in Winter and by mountaineers. These kinds of sleeping bags are usually selected based on the Temperature Ranges mentioned.

The materials used in the sleeping bags are the backbone behind the bad weather resistance technology provided in the bags. These materials are usually synthetic and are usually balled up instead of single strands. The selection of synthetic materials is also to provide the necessary insulation in wet places.

There are also sleeping bags made from goose down material. It provides more warmth but does not work well in wet places.

A bag rated as -28 is meant to be used in extreme cold condition. Nylon material is used in both shell and liner as it is more durable and doesn’t rip off. It is also windproof. The shells are usually coated with chemicals like DryLoft that work as a waterproof barrier. The fill is usually Down as it provides more warmth but synthetic fills are also used in the place of Down nowadays.

The main advantage of using Down is

  • Its lightweight
  • Gives better Insulation
  • Can be compressed to make packing easier

But Down is not good in wet places, for people with allergies and requires a lot of care.

The main advantage of using synthetic material is

  • Keeps us warm all the time
  • Non-Allergic
  • Cheap

But it is heavier and bulkier than Down and its lifespan is shorter.

Hence, the choice is made in accordance with one’s requirement.
