I have a Montbell UL Thermawrap jacket. 1.5 years old…Not much loft left at all. Feels almost like just two layers of nylon with almost nothing in-between. Of the currently-available synthetic insulations (for puffy jackets) which ones can maintain their loft given that they will be stuffed into a backpack most of the day, only to be used mostly at camp?
Love the fit of my Montbell, but, at this point, almost no loft at all! Basically, I want to find a puffy jacket, 10-12 oz in weight good for damp Pacific NW climate. Â Dry down?
