Before buying, define the use: bivouac, family camping, alpine trek, or lightweight raid. Consider your sleeping equipment for camping and the space in your backpack. CocoonPeak offers a useful selection if you want to compare quickly.
Mummy (fitted hood): excellent warmth-to-weight ratio. Ideal for hiking and high mountains.
Rectangular: more comfort and freedom of movement. Suitable for family camping and nights in a refuge.
Semi-rectangular (sarcophagus cut): compromise between comfort and thermal performance.
Double: for couples sleeping together.
Bivouac / ultralight: very compact but less comfortable when it's cold.
Temperature: look at the comfort / limit / extreme values. Choose a bag with a comfort temperature at least 5 °C lower than the minimum expected temperature for cold nights.
Insulation: down (warmer and compressible) vs synthetic (better in humidity, cheaper). Down has a loft power expressed in fill power.
Weight and volume: for hiking, aim for the lightest possible without sacrificing necessary warmth. An ultralight bag can weigh less than 800 g; classic hiking bags are between 800 g and 1,400 g.
Materials: water-repellent shell, breathable lining, DWR treatment to resist moisture.
Cut and comfort: length (regular/long), width, adjustable hood, anti-cold collar, reversible or snag-free zipper.
Accessories: internal pockets, anti-draft fabric, compatibility with pillow or mattress.
Summer: bags 5, 10 °C comfort. For very warm nights, consider a lightweight sleeping bag.
3 seasons: bags 0, 5 °C comfort, versatile from spring to autumn.
Winter: bags below 0 °C comfort, even -10 °C or less depending on altitude.
Ultralight: < 800 g, for minimalists.
Light: 800, 1,200 g, a good compromise for multi-day hiking.
Comfort: > 1,200 g, for more warmth and comfort at camp.
Choose based on the length of the trek, type of accommodation, and your cold tolerance.
Long-term storage: store the bag uncompressed in a large mesh bag or hung. Do not leave compressed in its compression sack.
Washing: wash rarely. Prefer a gentle hand wash or machine wash according to the label, with special down detergent for feather bags.
Drying: dry completely in a tumble dryer on low heat with tennis balls to re-fluff the down. For synthetic, low-temperature drying is also recommended.
Re-waterproofing: apply a DWR treatment if necessary.
Small repairs: use ripstop patches or fabric glue to close tears.
For a good sleep, consider choosing a mattress for camping and trekking that is suitable: insulation and comfort are essential.
If you prefer an alternative solution for nights in the forest, a quality camping hammock can replace a mattress + bag depending on the site and weather.
To carry the gear, a well-fitted Ortovox backpack for men and women helps distribute the load.
Some people look for specific models: for example, choosing a Pajak sleeping bag can meet specific technical needs.
Combine your bag with technical layers: consider Rab equipment for body insulation.
For technical hikes, Salewa hiking equipment often completes the set (shoes, jackets, etc.).
For robust and technical accessories, also check Mammut equipment.
