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.
Where to Buy
Here's what other sites are saying:
Warmer than a heavyweight technical fleece and lighter than a pair of expedition gloves, the Montbell Women's Ultralight Down Jacket means cold-weather protection without a weight penalty. Other down jackets eat up pack space, but this sub-seven-ounce goose-down layer packs down to the size of a water bottle, leaving plenty of room for your backcountry gear or other travel essentials. A trim fit flatters your fit physique and also makes it stunningly simple to slip a hardshell over this cozy piece.Down insulation is the insulation gold-standard. Feathers and plumules intermingle, producing a lattice-like network of open spaces and solid bits. Air gets trapped in the open spaces and creates a stalwart barrier between cold outside air and warm air your body kicks out. So long as the down stays dry, you stay warm. Part of the reason down dominates the insulation world is that the warmth-to-weight ratio can't be beat; you get a whole lotta warm for very little weight. This is where you start paying attention to the number associated with the fill-power. Specifically, that number describes how much space a single ounce of down occupies. Since down works by trapping air, it follows that the more space a single ounce of down takes up, the more air it can trap, and the more warm you stay on a per-ounce basis. By using 800-fill power down in this jacket, you stay warm without schlepping a full flock on your back.Sewn through construction means the down stays in place so you stay warm all over. This jacket shakes off spits of rain due its DWR coating, and ripstop nylon stops snags before they start. Two zippered hand-warmer pockets give your paws a protected place to park. A stuff stack comes with this jacket for easy and organized packing.
The challenge: create the lightest and warmest insulation layer possible, without compromising on fit or features. The result is the highly refined MontBell Ultra-Light Down Inner series. This family of products delicately balances the characteristics that define reliable ultra-light apparel. For example, the U.L. Down Jacket weighs less than most cotton Tee-shirts, blocks an amazing amount of wind, and is warmer than most heavy fleece jackets, while compressing to the size of a 32 ounces water bottle. Specifically designed as a replacement for the heavy and bulky fleece garments used by many backcountry enthusiasts, the U.L.Down Series is what you need when warmth is critical, minimal weight is paramount, and space in your pack is at a premium.
