Korišćenje i održavanje - Vreće za spavanje


Down: a traditional choice for excellent heat insulation and minimum size. The down — more valued — to feather ration is the ID for a down sleeping bag (e.g. 80/20 means 80% down and 20% feathers). Heat insulation, measured by the CUIN unit, is defined as the loft height, in inches, of 30 g of down. A SEPARATE CHAMBER construction guarantees more even down distribution.

Hollow fibre: for the utmost comfort and heat insulation, less absorption of moisture and extremely easy washing. Manmade fillings facilitate the diffusion of body heat in the sleeping bag, retaining it uniformly. The fibres are arranged in independent LAYERS to form barriers against the cold.

Maintenance and Washing

Maintenance and washing
Wash by hand or machine wash at 30° using a delicate cycle. Do not dry clean. Dry in the open. Keep the sleeping bag out of its storage sack when not in use.


Sleeping Bags Temperature

European Standard En 13537

In order to standardise determination of reference values for comfort temperatures, a European standard for the thermal testing of sleepingbags was established in 2004. Obviously this has to do with a laboratory test on an instrumented dummy which can never reproduce thephysiological–physical conditions but which standardises the test conditions that were previously differentiated for each individual laboratory. Contrary to what might be assumed, the comfortable temperature of a sleeping bag, however, does not depend solely on the quantity/qualityof the down used or on its construction but it is affected by different important factors. For this reason, though availing of the determining results of the laboratory test, as required by the standard, Ferrino continues on the roadit has undertaken for many years, using field tests, collated each year in our High Lab laboratories on the basis of appraisals whichcustomers, on their own initiative, give to our products.


Test con normativa EuropeaMaximum comfort temperature is the maximum temperature, which allows a standard man to sleep without perspiring excessively. It is established with the zips of the sleeping bag open, the arms out and the hood open.

Comfort temperature is the temperature value (referred to a standard woman), which facilitates a full night’s sleep in a relaxed position.

Lowest comfort limit defines the minimum temperature (referred to a standard man) in which it is possible to sleep in a curled up positionfor eight hours without waking.

Extreme temperature is the minimum temperature at which the sleeping bag protects the user (standard woman) from hypothermia. It allows six hours of uncomfortable sleep without the internal temperature decreasing to a dangerous level.


When choosing your sleeping bag we suggest you consider comfort temperatures and intermediate temperatures depending on your level ofphysical fitness. Feeling hot or cold is caused by our body producing greater or lower quantities of heat compared to what we are losing to the surroundingenvironment.


Test con normativa europeaMetabolism: When sleeping a person generates 75–100 watts of heat, depending on various factors like age, gender, weight, habits andpsycho-physical conditions.

Weight: Overweight people usually have a slower metabolism. In general they eat more than they consume. When we undertake anymountaineering activities we often take in less calories than we consume. Overweight people will be able to take energy from their fatreserves and also avail of greater natural insulation than thin people.

Age: Metabolism is connected to age. An old person generally generates less heat and therefore feels colder than a young person.

Gender: Women feel cold more than men, so much so that the standard comfort temperature for women is 5°C higher than that for men.

Habits: The majority of people living in the western world live in homes fitted with central heating, work in offices with air conditioning andmove around in an air-conditioned vehicle. This lifestyle reduces the body’s ability to withstand the cold.

Experience: Experience and familiarity with our open–air sleeping equipment help to obtain its optimum performance. First-time users willusually feel greater discomfort and colder than experienced climbers.

Physical fitness: If we lead a sedentary lifestyle and we submit ourselves to a difficult excursion, we immediately become aware of theeffort. Fatigue reduces the production of heat and thus leads to our feeling cold.

Some useful advice

Choose a sleeping bed that is suited to the activities you think you will carry out, considering temperature, humidity, and the size and weightof the sleeping bag, seeking the assistance of a qualified salesperson. Remember however that to sleep well, other factors are important,and these include:

Investing in a good mattress, which as well as helping you to sleep comfortably, will also provide adequate insulation from the ground.

Buying a good tent, which can protect you from bad weather. Sleeping in conditions of direct exposure to the wind and/or in particularlydamp conditions will lead to a considerable increase in heat loss due to convection.

Always checking long–term weather conditions, in fact these can change with little warning and the equipment you choose on departurecould be unsuitable in the case of worsening weather.

Equipping yourself with additional clothing, which in cold conditions can be worn under normal clothing and can also be used at night. Furthermore if you foresee below zero temperatures equip yourself with a balaclava and bivouac socks.

Eating correctly otherwise your body will produce less heat and become more sensitive to the cold as a result. Drinking is also important asdehydration reduces the body’s ability to produce heat. Avoid alcohol, which only gives an initial sense of heat, after which you will feel colderthan you did before.

Keeping your equipment dry as wet sleeping bags (especially with down filling) give lower insulation than dry ones. For this reason, Ferrinooffers sleeping bag covers on different models to protect your product from damp conditions.In any case, as soon as you are able to, dry your sleeping bag in the open air, for example on the top of the tent during the day. Air your tentwhere possible, maintaining an air change that is sufficient to reduce the problems of condensation.
