Trekking sleeping bag
24 products
The selection covers all needs from summer trekking to winter bivouacking, with models featuring 650 to 800 cuin natural down filling. Comfort temperature and weight are the two central criteria for refining your choice according to your planned itinerary.
Weight and compressibility: the priorities for a trekking sleeping bag
For self-supported hiking over several days, the weight of the sleeping bag represents a significant portion of the total load carried. An ultra-light sleeping bag with 800 cuin down filling can achieve weights under 600 g for a comfort temperature of 0°C, whereas an equivalent synthetic model generally exceeds one kilogram. Compressibility follows the same logic: a compact down bag with 800 cuin packs into 8 to 12 liters when compressed, freeing up precious space in a 35 to 45-liter backpack. For long-distance routes like the GR20 or the Tour du Mont-Blanc, an ultra-light trekking sleeping bag under 700 g with a compressed volume of less than 12 liters is an achievable goal with 800 cuin filling. A lightweight warm sleeping bag combines these two criteria without sacrificing the thermal range: high-density down filling is the only option that achieves this ratio in practice.
Natural or synthetic down for trekking in France?
Trekking down with natural filling offers the best weight-to-insulation ratio for trips in dry conditions, typical of high-altitude bivouacs in the Alps and the Pyrenees in summer. Synthetic filling retains partial insulation in damp conditions, a real advantage for mountain ranges exposed to showers or during traverses with heavy nighttime condensation. For classic alpine routes in peak season, natural down is objectively more efficient in terms of weight and volume. For trips in mixed conditions or more humid regions, a model with hydrophobic down offers a relevant compromise. A detailed presentation of both types of filling based on the type of trip is available in the down vs. synthetic guide.
Which comfort temperature should you choose for trekking and bivouacking?
The choice of thermal range depends directly on the mountain ranges and seasons targeted. For summer bivouacs between 1,000 and 2,000 m in France, a bivouac sleeping bag with a comfort rating of +5°C to +11°C covers nights from June to August in the majority of situations. For spring to autumn trips above 1,500 m, a 0-degree sleeping bag is the most versatile choice, covering nights down to -3°C with an appropriate sleeping pad. For late-season treks or for those who get cold easily and want a comfortable margin, a model with a comfort rating of -5°C or -10°C is preferable. The rule of thumb: plan for a margin of 3 to 5°C compared to the coldest expected night, while taking the insulated sleeping pad into account (minimum R-value of 3 recommended for high-altitude bivouacs).
500 g ultra-light sleeping bag: what you need to know
An ultra-light sleeping bag under 500 g is achievable using 850 cuin down with 10-denier fabric, but it involves concrete compromises: a more fragile outer fabric, a thermal range generally limited to nights above +5°C, and reduced durability for frequent use. This format is intended for ultralight summer use, not as a versatile 3-season bag. For a more robust lightweight sleeping bag with a thermal range down to 0°C, models between 700 g and 1 kg with 800 cuin down represent the best balance of daily use, durability, and thermal performance for a 3-season trekking sleeping bag.
