TEMPERATURE SCALE MIN °C 30 COMFORT °C MAX °C T° EXTREME T° COMFORT T° MAXIMUM Minimum temperature at which the sleeping bag will ensure 6-8 hours of sleep without the risk of hypothermia. Minimum temperature of the surrounding air, at which the sleeping bag ensures 8 hours of comfort and continuous sleep. I.e. it is the minimum temperature at which the sleeping bag is perfectly fulfilling its function. Maximum temperature at which comfort sleep is possible without increased body perspiration and feeling of excess warmth. At high temperature the sleeping bag can be opened. However, when choosing a sleeping bag you have to take into account that susceptibility to the cold differs with different people and age groups! People with stunted metabolism are considered to be the most susceptible to the cold. Women, children and elderly people have the same high susceptibility to cold. DESCRIPTION Polyester – polyether fibre. The fabric has high durability and wear-resistance. It holds the shape well, does not wrinkle, and is resistant to light. Polyester RipStop – a type of fabric with special reinforcing weaving pattern. Equidistant reinforcement strands are crosswise introduced into the structure of the fabric. Polyester with the addition of mesh improves fabric properties, prevents tearing and ripping of the fabric. Diamond RipStop weaving – reinforcing strands are located diagonally and form a rhombic pattern on the fabric. Honeycomb RipStop weaving – reinforcing strands form a honeycomb pattern on the fabric. Nylon – manufactured from polyamide strands. Durable and wear-resistant material protects from wind and removes condensed water vapour to the outside. Fast drying material with good air exchange properties and water repelling coating. Nylon RipStop – to increase the durability of the fabric without increasing the weight, thicker and more durable strands are introduced into the fabric. Cotton – qualitative cotton fabric. Natural fabric, hypoallergenic, heat-saving, soft, pleasant to touch, perfectly absorbs moisture, ideal for family travels. Polycotton – a mix of cotton and polyester. The fabric is just as pleasant to touch as cotton; durable; breathing. Micro Loft insulation made of silicone-coated polyester fibre. Has the same woolliness as down feather and small weight. Good thermal insulation properties! Super Loft – silicone-processed polyester fibre. Fibre has several internal air channels, thus allowing the fibre to retain warm air inside and ensure good thermal insulation properties. The insulation has greater capacity for compression, thus allowing considerably reducing the weight and dimensions of the sleeping bag. Warm Loft – silicon-processed polyester fibre. Fibre has one internal air channel, thus allowing the fibre to retain warm air inside and ensure good thermal insulation properties. The insulation has capacity for compression, thus allowing reducing the weight and dimensions of the sleeping bag. COBRA 18 50 NORFIN One of the most significant selection criteria for a sleeping bag is its temperature properties. Sleeping bags are manufactured with certain temperature conditions in mind (according to the season): summer sleeping bags designed for considerably high night temperatures; interseasonal sleeping bags, when comfort temperatures drop below 00C; winter sleeping bags ensuring sleep at
