Great for backcountry travel and a winter mid-layer.

Great for backcountry travel and a winter mid-layer.


  • Warmth to weight
  • Long enough in back
  • Good layering piece


  • Pockets don't zip if wearing as outer layer
  • Separate stuff sack
  • Stretchy cuff can rip easily (but helps fit)

I bought this jacket for an insulating layer for backpacking for work in the Central Sierra Nevadas. It gets cold at night and I needed a jacket that wasn't fleece, that I could cook in, sleep in, and put on in the mornings.

This jacket is long enough in the torso (I have a longer torso) and in the arms (some other brands are too short in the arms). Of course right after I bought this, the slightly heavier version of this, the Thermawrap BC Jacket, with zip pockets came out. If I could make a purchasing decision again, I would have leaned more toward the Thermawrap BC in terms of functionality as an outer layer in the backcountry. 

For skiing in general, I liked the warmth and wicking properties of this jacket in colder weather under a shell. I paired this with the Rab Latok Jacket and this system is my favorite for colder days doing front and slackcountry skiing.

Down sweaters don't wick in the armpits and chest/back for me. The Montbell UL Thermawrap did.

The evolution of our U.L. ThermawrapTM Series continues. Updates to these well traveled pieces are based on beta received from countless wilderness devotees. We have sourced a new type of 15-denier Ballistic Airlight nylon for the outer shell that retains the same ultra-light weight and impressive tensile strength, but is far less shiny, has, a softer hand, and makes very little noise with movement. Cuffs on the jacket and parka 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 on the jacket and vest creating a more refined fit. The series is rounded out by a new women s specific vest. Rest assured, while we have tweaked some details, the ThermawrapTM concept remains the same: simple, light weight, synthetic insulation that remains thermally efficient when wet. Whether it be a frigid mid-winter bike commute into the office or a harrowing belay high on the Compressor Route, our ThermawrapTM Series will keep you covered.

The Mont Bell Women's U.L. Thermawrap Jacket is their original ultra light synthetic concept jacket. The blueprint for its success: simple, lightweight, compressible, and thermal efficiency when wet. We utilize Exceloft, an extremely durable high loft insulation that dries quickly and retains less than 1% of its weight in water. Ballistic Airlight 15 denier nylon wears well and fends off all but the harshest of winds. This innovative blend of materials and design provides the warmth critical when traveling in mixed conditions.

Montbell tapered the shape of this jacket to fit a female mountain-goers physique, and they added elastic panels at the cuff and hem for additional comfort and stretch. Stash this sub-eight-ounce jacket in your pack and you'll forget it's there until it's time to fend off bitterly-cold alpine weather.
