1 / 4




What is your primary activity?
The type of activity determines priorities: weight, comfort, cold resistance, or durability.
đŸ„Ÿ
Trekking / Hiking
Long-distance trails, backpacking, lightweight bivouacs. Priority: weight/warmth ratio.
â›ș
Camping / Leisure
Family camping, van-life, festivals. Priority: comfort and price.
đŸ”ïž
Mountaineering / Extreme Cold
High mountains, winter, expedition. Priority: extreme insulation.
🧭
Versatile / Beginner
Mixed usage or first purchase. Priority: 3-season versatility.

What minimum temperature do you expect to sleep in?
The lowest expected night-time temperature. In the mountains, subtract 5°C from the valley temperature for every 1,000m of altitude.
☀
Above 5°C
Summer, low altitude, June–September camping.
🍂
0°C to 5°C
3 seasons, shoulder-season mountain trips, summer Alps/Pyrenees bivouacs.
❄
-5°C to -10°C
Late autumn, high altitude, moderate winter.
đŸ„¶
Below -10°C
Winter mountaineering, expedition, high-mountain bivouacs.
What is your budget?
Budget influences the type of fill (down or synthetic) and the weight/warmth ratio.
💰
Under €120
Synthetic or entry-level down. Occasional use.
💰💰
€120 – €250
High-performance down. Good balance of weight, warmth, and durability.
💰💰💰
Over €250
High-performance down with high fill power. Ultralight, 10+ year lifespan.
How important is weight to you?
In trekking, every gram counts. In car camping or van-life, comfort comes before weight.

💡 Field Tip
The indicated temperatures correspond to the comfort temperature (EN 13537 / ISO 23537 standard) for standardized sleeping bags, measured in a laboratory with an insulating sleeping pad (R-value ≄ 5.5), long underwear, and the hood closed. Actual conditions (altitude, humidity, wind, fatigue) can affect thermal perception.
