Jei kada pirksite miegmaišius, tai ši informacija gali praversti. Miegmaišiai, kurių temperatūros parašytos pagal EN 13537 standartą, yra charakterizuojami keturiomis temperatūromis. Įdomiausia dalis tai, kad “extreme” temperatūra ant miegmaišio reiškia štai ką:

Tokioje temperatūroje gali išbūti iki 6 valandų užsęgęs visas įmanomas angas, susisukęs į kamuoliuką ir drebėdamas, bei bandydamas visaip išlaikyti šilumą. Galimi nušalimai, sveikatos sutrikimai, mirties rizika. Nepatyrusiems – tai pavojinga temperatūra.

Ištrauka iš standarto:

Lower temperature limit – in this case experienced user (woman) of sleeping bag (who adapts her clothes and position in sleeping bag to surrounding temperature and is able to take advantage of all possibilities of the sleeping bag) must expect strong feeling of cold. There is a risk of chill and health injure that can lead to death.
This temperature is calculated for standard woman (25 years old, 60 kg, 1.60 m tall, body surface 1.62 m2) when strongly exposed to cold that can last only for limited period, no more than 6 hours. Experienced user of sleeping bag is curled into ball in the sleeping bag and minimizes heat loss through sleeping bag (medium temperature of skin is 29 °C) and she shivers and elementary metabolic production rises. For inexperienced user this temperature is dangerous and it can lead to hypothermia and even to death.
