The most "magical" sleeping bag in the world has its own air conditioner but no electricity. How to make it warm in winter and cool in summer?

Winter is synonymous with "severe cold". In the cold winter, I can't wait to sleep with the stove and stay at home for 24 hours. For some tourists, in order to pursue excitement and explore the frozen snow-capped mountains, the biggest problem is "accommodation", which is very casual for them and only needs a super convenient sleeping bag.

This magical sleeping bag is really good news for adventurers, and it can automatically adjust the temperature, which is equivalent to an "indoor small air conditioner". This sleeping bag is called Polarmond, which was invented by a Swiss company. Don't worry even in the environment of MINUS 25 to 30 degrees, it can be automatically adjusted to a comfortable temperature without electricity, and it is very convenient to carry out, with almost no restrictions on environment and facilities.

Polarmond sleeping bag consists of tent, damp-proof pad and sleeping bag. The biggest difference from ordinary sleeping bags is that it has the function of heat preservation and cooling. This sleeping bag consists of two parts, and the surface insulation material has waterproof and windproof effects, just like a protective shell. Even if it rains and blows, it will not affect the interior at all, and it can also ensure that the hot air will not be lost.

If you think this sleeping bag is airtight and damp, it's all wet. This sleeping bag can absorb water vapor and is filled with wool, which is not only comfortable, but also can better store heating. The closest inner layer also has dehumidification effect. After two layers of intermediate circulation, it can ensure that cold air goes out and warm air comes in, so that the sleeping bag keeps good breathability.

After entering the sleeping bag, except for the head breathing outside, other parts are well protected in the sleeping bag. Even if it is particularly cold outside, the sleeping bag is warm. It is very necessary to equip such a sleeping bag for outdoor travel.

However, if my sister travels with this sleeping bag, it's better to find a man to accompany her, otherwise, she has not gone far with this sleeping bag, and her physical strength will be almost consumed, so it will not be worth the candle.

The price is convenient, this sleeping bag is not cheap, and the price is 260 euros, equivalent to about 2000 yuan. What's up, friends? Do you like this sleeping bag?
