This thread is full of valid points. (And i don't smoke!) I bought it based on its warmth-for-weight ratio. The fabric that goes into ultralight clothing is definitely more prone to fire damage.

However, I will say that this has held up to numerous campfires. It's just that I was dumb and wore it when burning invasive brush in the snow. It was a massive fire and embers shot out over me when I was throwing more stuff on. Now I wear a heavy flannel over it, or wear my Fjallraven canvas instead.
