Sleeping bags can be incredibly expensive. Getting a branded one with goose down can easily set you back some 400-500€. Thanks to our French friends at Decathlon though I had gotten one for less than 100€ that claims to keep you warm even in temperatures slight below zero.
Down is lighter, smaller and warmer than most cheap synthetic materials, however as soon as it gets humid or even wet it looses pretty much all of its insulation properties. On a trip where we wouldn’t need the sleeping bags on most nights we could only take something small and lightweight. Be it camping in New Zewland’s frosty spring nights, and especially now in Nepal at higher altitude, I was happy about having taken that 1 extra kg.
