Best praise vs top criticism for TETON Sports Celsius
“R1 air is beautiful for really cold weather as a mid layer, great for low activity stuff like glacier hiking and climbing, also great as casual wear in mid teens Celsius. Not so great as a hiking layer”
“I have not tried Forclaz down jacket yet, but I have been using Nano puff for over a year and I think it is a little bit overhyped. I mean it is still a good jacket, but I think for this price you can get something better and more packable like Cumulus jacket. [https://cumulus.equipment/eu\_en/clothing/men.html](https://cumulus.equipment/eu_en/clothing/men.html) I tried Nanopuff in different conditions, I don't recommend wearing it in temperatures below 0 - 3 degrees (Celsius).”
