When we talk to you about bivouac in winter, you think directly of the fantastic landscape that you will be able to observe. However, this kind of getaway involves aspects that are more difficult to take into account, which is why it is essential to be well equipped in order to be as well prepared.
If you are going to bivouac during the winter, you will have to respect the three-layer rule (breathable / thermal / protective).
– The first layer, correspond to the breathable layer which has the function of wicking away your perspiration. Water is the cold’s best ally and will therefore be your worst enemy. Opt for a wool or breathable synthetic fiber T-shirt and forget about cotton which is a hydrophilic material.
– The thermal layer will compose your second layer. Its function will be to conserve the heat produced by the body by trapping the air. The choice of a fleece or a wool sweater will be perfect for this intermediate protection.
– The third and final will be the protective layer. It will allow you to protect yourself from all outdoor weather like rain, wind, but also snow. The choice of a puffy jacket or a jacket hardshell is ideal.
Each protection has specific functions. Indeed, the clothes which meet a very precise need lose in effectiveness on other properties. For a optimal protection, it is essential to maintain your equipment, because dirt and grease block the passage of air. An outfit that is too tight or too loose will not protect you as it should, which is why it is important to wear clothes that fit.
