Thermarest Sleeping Bags

Thermarest Sleeping Bags: to keep you warm at night

Nothing beats a good night's sleep in warmth to prepare for a new adventure. Choosing a good sleeping bag is essential. Yes, you will spend as much time (if not more for heavy sleepers) in your Thermarest sleeping bag as in your hiking boots. There are many factors that can disturb your sleep: temperature, humidity, comfort... Making the right choice for your Thermarest sleeping bag is crucial.

Down, synthetic filling, insulation, comfort temperature, rectangular or mummy shape... we will share all the secrets to help you choose your Thermarest sleeping bag.

The first criterion to consider when choosing your Thermarest sleeping bag is the filling. Just like your women's down jacket or your men's down jacket, there are two types of filling: natural down (usually goose or duck) or synthetic material (Primaloft® or Thermolite® being the most well-known). When choosing your Thermarest sleeping bag, make sure it perfectly suits your adventure, but especially the environment in which you will be. The Thermarest sleeping bags with down filling attract and absorb water very easily, so if you plan a trek in a very humid area, opt for a synthetic sleeping bag.

The Thermarest sleeping bags filled with synthetic material also have their disadvantages compared to natural down: less compressible, heavier, slightly less warm...

The outside temperature is also a determining factor in choosing your Thermarest sleeping bag. You won't need the same Thermarest sleeping bag if you decide to face the cold of the Lofoten Islands in winter or the warmth of Corsica for the legendary GR20 crossing.

There are therefore three temperature benchmarks to guide your choice: the comfort temperature, the limit temperature, and the extreme temperature. The comfort temperature is the temperature at which you can sleep "relaxed" without any discomfort. You will start to feel the effects of the cold from the lower limit temperature, without putting your life in danger. However, the extreme temperature is a very important indicator; it is from this point that your risk of hypothermia will be high. Be sure to choose the right Thermarest sleeping bag that will perfectly meet the needs of your future adventures.

Finally, you should also consider the shape of your Thermarest sleeping bag. If you tend to feel confined and suffocated in a closed space, we recommend choosing a rectangular Thermarest sleeping bag. You may lose a bit of heat, but it's for the comfort of your sleep, so it's definitely worth it. Otherwise, the mummy or cocoon Thermarest sleeping bag remains the perfect model for bivouacking. Be careful, there are also models for men and women, as well as sizes that vary. So find the model of Thermarest sleeping bag that best suits your body shape and size.

Why choose a Thermarest sleeping bag?

You will understand, your Thermarest sleeping bag should primarily be chosen based on your needs and the environment you will be in. If you want a complete sleeping bag, we recommend a Thermarest sleeping bag for 4 seasons, or 3 seasons (if you don't plan to bivouac in winter).
