Jeremy wrote a review of MontBell Ultralight Thermawrap Insulation Parka - Men's on June 22, 2010
Took this with me on a June trip to the Cascades, 12 days of hard use, with it on most of the time (including in the sleeping bag). It did the job of keeping me warm, and weighs practically nothing. I love that its thinner than your typical down jacket, so putting a rain/wind shell over this doesn't require upsizing your other gear. Starting to show some wear already on the cuff, but I totally expect that given the use.
