The 2011 Spring Montbell UL Thermawrap Jacket is only 8.8 ounces, insulates when wet and is wind and water resistant. As light as a cotton t-shirt, but incredibly warm for its weight!
The fabric now has a softer hand, is far less shiny, and makes very little noise with movement. Cuffs now feature a wedge shaped stretch panel for increased comfort and durability. Similar elastic wedges have also been added to both sides of the hem creating a more refined fit.
Full length coil zipper has a wind blocker behind the zipper. Two hand warmer pockets and a micro-fleece collar lining increase comfort.
Exceloft synthetic insulation acts like down, providing the best combination of insulation, lofting, durability and compressibility. Exceloft retains heat and maintains its lofting properties 10-20% better than other leading synthetic insulations.
Unlike down, Exceloft retains 80% of its insulation value when wet! Exceloft absorbs less that 1% of the water that it comes in contact with, making it highly resistant to saturation and extremely fast drying.
Everyone that picks this jacket up is completely shocked by how light and soft it is. It compresses down to slightly larger than a softball and comes with a stuff sack that weighs 8 grams. This is a favorite among the GearZone.com staff.
The shell is made out of Ballist Airlight ripstop nylon that is incredibly soft, light and highly wind resistant. This jacket is so light you will not have an excuse to leave warm insulation behind that could save your life.
Ideal for adventure racing, backpacking, climbing, snowshoeing, trail running, etc.

Ballistic Airlight™ - 15-denier Ballistic Airlight™ nylon is astoundingly thin, weighing less than half of a 45-denier nylon of normal shells while offering equal strength. This strength comes from the manufacturing process where the nylon is repeatedly stretched to align the molecules, much like the tensilizing of steel, resulting in an extremely light weight, wind resistant, breathable and water resistant fabric.
Exceloft™ - Montbell's Exceloft™ insulation uses 8-denier polyester threads as a structure to intertwine with extra thin 0.7-denier threads that add more air pockets and resilience. As a result, Exceloft™ products rival the warmth and weight of other synthetic insulations. Exceloft™ retains less than 1% of their weight in water. Exceloft™ will keep you warm even when wet.
The Warmest Synthetic Jacket for its Weight!
