DAron wrote a review of MontBell Thermawrap BC Insulation Jacket - Men's on September 23, 2011
This jacket is it! I had been in the market for a light weight, synthetic, packable jacket for my multi-day trips. I've taken this jacket on a 4 day/3 night backpacking adventure around the Four Pass Loop in CO and a single overnight in the snow to the Uncompahgre Wilderness. This jacket more than stood up to expectations. Very light and packs down to about the size of a Nalgene without compromising warmth & functionality. I snagged it several times on tree limbs or rocks expecting to have ripped a hole and see fibers falling out, but there wasn't even evidence of a scratch. When I ordered this jacket, I also ordered a Patagonia nano-puff jacket to compare. The Mont-Bell was not only more stylish, it fit better too (the Patagonia was ballooning out around the waist. Kind of felt like wearing a trash bag). I appreciate the flex material down the sides that allows stretching if you need it, but without the hassle of cinching a draw cord. The dual chest pockets are a plus as well. I am 6'1", 165 (tall and skinny) and ordered a Medium. The fit is nearly perfect. I wish it were just a tad longer, but with my frame, I'm always stuck deciding between a Medium that's a bit short, or a Large that's too wide. If you're contemplating, buy this jacket...well worth the investment!
