By features
—
Expeditionary. The most "extreme" type of sleeping bags, designed primarily for use on long trips, including in the cold season and in high mountains. A prerequisite for expedition bags is a low extreme temperature (see below) — -20 °C and below; exceptions are found only among children's models. As for the design, bags of this type are often equipped with hoods,
thermal collars, they can provide fastening (for more details, see "Characteristics").
—
Trekking. Sleeping bags designed primarily for use on hiking or cycling trips. Their key features are compactness and light weight, which make it easy to transport on your own. Because of this, trekking sleeping bags are much more expensive than camping ones with similar characteristics — lightweight and at the same time high-quality materials are not cheap. So for a permanent stay in one place, it hardly makes sense to pay attention to this category. Also note that sleeping bags for this purpose are designed mainly for use in the warm season — in spring / autumn and/or summer — and are made mainly in the form of cocoons, although there are exceptions to both rules.
—
Camping. A type of sleeping bag designed to provide comfort while constantly staying in one place in relatively uncomplicated conditions. Such a bag can be useful, for example, at a picnic with an o
...vernight stay, a multi-day summer festival, etc.; but for long-term wearing “on oneself”, camping models are poorly suited due to their relatively large dimensions and weight. The seasonality of sleeping bags for this purpose may be different, but it is worth noting that most of these products are made in the form of blanket bags (see "Type").comfort t° (for men)
The comfort limit temperature of this sleeping bag.
Some manufacturers use their own criteria for specifying this temperature, but EN13537 is considered the generally accepted standard. According to him, t of the comfort limit is the lowest ambient temperature at which a man in thermal underwear can comfortably sleep in a sleeping bag all night (at least 8 hours) in a heat-saving position (curling up) without waking up from the cold. Such criteria are used taking into account the fact that men are less likely to get cold during sleep than women, and the acceptable temperature for them is slightly lower. Of course, in each individual case, comfort will also depend on the characteristics of the body and the preparation of the tourist. However, in general, the general rule is: if the sleeping bag is used by a man, then the minimum temperature at the place of lodging should ideally be between comfort t and comfort limit t; for a woman, a few degrees must be added to the comfort limit t, and it is best to focus on comfort t (see above).
This indicator is quite closely related to seasonality. So, for winter use, t of the comfort limit should be
less than -4 ... 0 °C ; in the warmest models, it can be very low,
-15 °C and below. In purely summer and even spring/autumn models, there are values of
+10 °C and even higher, however, if you are afraid of s
...udden cold snaps at night, it is advisable to choose sleeping bags with indicators of at least +6..10 °С, and preferably +1...5 °C(especially for the off-season).t° limit (for men)
Some manufacturers use their own criteria to indicate this temperature, but the generally accepted standard is EN13537. According to it, the comfort limit t is the lowest ambient temperature at which a man in thermal underwear can comfortably sleep in a sleeping bag all night (at least 8 hours) without waking up from the cold in a heat-saving position (curled up). Of course, in each individual case, comfort will also depend on the characteristics of the body and the training of the tourist.
t° limit (for women)
Some manufacturers use their own criteria to indicate this temperature, but the generally accepted standard is EN13537. According to it, the comfort limit t is the lowest ambient temperature at which a woman in thermal underwear can sleep in a sleeping bag all night (at least 8 hours) in a heat-saving position (curled up), maintaining thermal balance. Of course, in each individual case, comfort will also depend on the characteristics of the body and the preparation of the tourist.
