for the outsider inside of you
I think the traditional thinking was that the more expensive down bags were warmer, lighter, and packed smaller than synthetic bags, whilst synthetic bags were cheaper, dried quicker if they got wet, and were easier to maintain.
The K-Way Zermatt 950 Eco bag is a lightweight sleeping bag suitable for hiking in good weather. It is lightweight and has a comfortable fit. It is labeled with a temperature rating of -5°C Extreme / 0°C Comfort: I cannot agree with this at all, and could not recommend it for temperatures below 8°C.
