FREEFLOW(R) Lite is the ultralight PU-based technology behind the Montane 180, claimed by the company to be the world's lightest weight fully waterproof and breathable outdoor shirt. The concept of having a WP/B shirt, instead, of say, a jacket, was terminologically appealing to us: it's a good linguistic fit for the ultralight fringe.
The Montane 180 has a trim (but not too much so) cut with a drop tail, a half length zipper that offers good ventilation, and even a lined collar. Elastic drawcord hem, elastic wrist cuffs (nonadjustable), sleeves that are long enough, a roll-away adjustable hood with a wired peak, and water-resistant zippers for the neck and chest pocket means that for six ounces, the pullover is not completely devoid of features.
The Montane 180 will be available in blue, black, and for the stealth camping or hunting crowd, drab olive green.
Oh, one more thing: that six ounce weight is reported for a size LARGE, a size that fits into a stuff sack the size of a Yakima apple.
