MontBell U.L. Down Inner Jacket
Fill: 800 fill down
Price Paid: $80
I love this jacket. It did not fail me on a 10-day backpacking trip to Yosemite in May. I used it during freezing temperatures (probably around 20 degrees Fahrenheit), and it worked well. I also had a fleece sweater, a Marmot Precip Jacket, and some Under Armor. However, if you feel chilly, this beat everything I had to give some warmth.
It's probably not as warm as a jacket twice its size and 800 fill, but it is very light and warm. It's hard to believe that something so warm could fit into such a small and light package. I usually used it under my Precip Jacket, so I don't have many pics of it, but I did wear it to a restaurant. :-)
Fabric: 15 denier Ballistic Airlight nylon
Fill: 725 down
Price Paid: $129
This U.L. Down Inner Jacket from MontBell is everything the other reviewers said.
The down really springs back to full loft, more than anything except my U.L Super Stretch Down Hugger #7 sleeping bag and Alpine Down Jacket from MontBell. I think their down is superior to anything I have owned.
This jacket is 7.4 oz. overall and feels like it is not even in the packsack. I have to look, yes, it's in there !
This inner jacket length has the length for the coverage I look for in warm wear.
The fabric is silky soft, and also wind resistant.
Their description says this fabric has high tear strength and good abrasion resistence.
I will add, the durability is ample if you take care of your stuff. I will not be crawling through any barbwire fences.
