3 season sleeping bag
The sleeping bags -15 can be used both in store and in bivouac, as long as the weather conditions allow it. Now, from Vertic we want to remember that this comfort temperature is not indicated for summer, but rather for winter.
After a long day of activity, a good rest is essential to perform the following day. The success or failure during an expedition also depends on the rest, so it is very important to choose the model that best fits the demands of the terrain through which we move. On the contrary, failure waits around the corner.
But ... do you know how this mountain material works? They do not heat by themselves, but they do it thanks to the filling that they incorporate inside each of the thermal partitions.
The thicker the thermal partitions means it incorporates a greater amount of filling. This greater amount of filler allows to retain more air; heating and isolating thermally in better way. Its function, therefore, is simply to regulate body temperature.
A filling of feathers, although it is more delicate than a synthetic filling, offer higher thermal performance in the same amount of filling compared to synthetic. In addition, it compresses much more; something very important if we have to transport it in the backpack. Now, it is true that in humid environments their performance is reduced. Therefore, in our stores you can find waterproof bivouac cases to use when conditions require it.
Although most are water-repellent thanks to their outer fabric, they are not waterproof. Because, if they were, they would not perspire enough. And breathability is a necessary feature both to eliminate sweat in the form of vapor and to prevent condensation. In this way, a microclimate is generated that regulates body temperature during rest.
The thermal performances are marked by the quantity as well as the quality of the filling. For this, it is important to pay attention to two data.
The quality of the pen is determined by two numbers. An example: 90/10. The first number; in this case, 90, indicates the percentage of duvet. The duvet comes from the abdomen of birds such as the goose or the duck. It is much more elastic and lighter than the feather, in addition to being more expandable (it fills much better).
The 10, the other figure, indicates the percentage of feathers with cane existing in the filling; that is, those that are of lower quality.
On the other hand the CUINS (CUbic INches or cubic inches) indicate the quality of the filling. To have the right material in the forest, from vertical we recommend the use of sleeping bags -15 that, at least, have 600 CUINS. The CUINS mark the ability of the pen to inflate.
After use, it is important to ventilate it. Of course, no matter how wet it may be, you never have to do it by directly receiving the sun's ultraviolet rays.
When we do not use it and store it in the closet, it is important that it does not lose thermal performance. For this reason, our specialists recommend keeping it in the compression sleeve by first inserting the front part. It is very important that the feathers do not stay on a regular basis. Thus, we avoid that they are always in the same position.
