makuupussia

Makuupussi, commonly known in English as a sleeping bag, is a padded, insulated bag used for sleeping outdoors. It provides warmth and a barrier against ground moisture and wind, allowing outdoor sleeping in variable conditions.

Most sleeping bags are rectangular or mummy-shaped. Mummy bags provide better heat retention and lighter weight, while rectangular bags offer more space and comfort. Many designs include a draft collar, a draft tube along the zipper, a hood, and a full-length two-way zipper for venting and temperature control.

Insulation types include down and synthetic fills. Down insulation, typically from duck or goose, is lighter and highly compressible but loses insulation value when wet unless treated. Synthetic insulation is more resistant to moisture and easier to care for but heavier. European manufacturers often use EN 13537 temperature ratings, which indicate comfort and limit temperatures for an average user, useful for choosing suitable gear.

Shell and lining are usually made from nylon or polyester. Common shell fabrics include lightweight ripstop or plain-weave materials, while linings are smooth and comfortable against the skin. Care involves airing out after use, following washing instructions from the manufacturer, and drying thoroughly before storage. Store in a loose sack rather than a tight compression bag to prolong loft and performance.

History and use: The modern sleeping bag evolved from simple blankets into purpose-built insulated bags in the 19th and 20th centuries, driven by exploration and mountaineering needs. Today sleeping bags are widely used in camping, backpacking, mountaineering, and emergency preparedness, available in a range of weights, temperatures, and sizes to suit diverse conditions.
