Sleeping Bags: Material, Thermal Capacity and Weight

In other entries, we saw different types of sleeping bags, as well as the main parts of a sack. Today we will discuss the other 3 important characteristics of a sleeping bag: the materials with which it is made, the thermal capacity of the bag and weight.

Thermal capacity

This depends on the thickness of the insulating layer, the collar, insulation and hood latches. Manufacturers often indicate the temperature range for which it was designed sack. This gives a rough idea that can withstand temperatures. It is important to understand the nomenclature used in sleeping bags:

  • Extreme Temperature:Temperature lower limit that can withstand deltro sleeping bag before the user begins to damage in the body.
  • Comfort temperature:temperature with which the user feels comfortable in the sleeping bag.
  • Maximum temperature:maximum temperature where the user feels comfortable in the bag.

Therefore, the lowest temperatures you face should be very close to the comfort temperature sleeping bag you choose.

Tip:  It is important to remember that the environment where the sleeping bag will affect the final temperature you get are. A good soil isolated and tent closed properly will help keep warm.

materials

Here are some of the most typical materials used in sleeping bags, and a brief description of advantages and disadvantages of each are presented.

  • Cotton

Advantages:  It’s soft, it absorbs moisture generated by perspiration and retains heat in winter. Cotton flannel feels very warm and quite durable.

Disadvantages: It  is something heavy. When (apelotona) is apelmasa, it can be difficult to separate.

  • Nylon (Synthetic fiber)

Some plastic synthetic fibers are nylon, polyester and acrylic fibers. There synthetic fiberfill, such as Qualofil, Petsinclude, Hollowfill and Polarguard 3D.

Advantages:  It is lightweight, durable, easy care and protects from the cold. You can put in the washing machine without any problem. They are ideal for summer, and does not lose its insulation properties if there is high humidity. If it gets wet, it dries quickly. Its price is lower.

Disadvantages:  They get dirty xanax easily, is not as warm as cotton and sweat sticks to the skin. Sleeping bags are a little heavier than the feather, but still very light and more comfortable option.

  • Feather

The feather quality is expressed in the mixture the amount of pen and nerve. A sleeping bag with feathers 90/10 is better than 80/20. The amount of feather in a sleeping bag is expressed in cuin (cubic inches).

Advantages:  It is the best insulator, can expand and compress better than fiber and takes up less space when the bag is in its case, so it weighs less.

Disadvantages:  They are more delicate than synthetic fiber and must avoid getting wet or damp as it loses its insulating capacity. Nor it can often be washed as the case of the fibers and should be performed with special products, because otherwise, the Pen (apelotona) cakes and voids are created within the chambers of the bag. It is more expensive, if it gets wet drying costs.

Tip:  If you want a sleeping bag for general use is most recommended one of synthetic fibers.

Weight

The weight depends on the material and dimensions of the bag. Nylon bags weigh less than cotton and are easier to wash and dry. Watch your bag and try not to get wet during the crossing!
