Review by: McKenzie Long ⋅ Senior Review Editor, OutdoorGearLab ⋅ September 22, 2013  
This is the jacket to buy if your style is light and fast and you need an insulated layer. Its thinness makes it a great mid layer or a quick and easy outer layer on a long and cold climb. Since it stuffs into a sack, you can pack it small and bring it with you easily. For $34 more you could get the Patagonia Nano Puff, which weighs three ounces more but zips into an interior pocket and has a carabiner loop to clip to a harness, which is slightly more handy. If you need a thick and warm jacket, you would be happier with the Arc'teryx Atom AR Hoody - Women's. If you are looking for an insulated jacket that breathe well, go with the Rab Strata Hoodie - Women's.

Performance Comparison

As another way to save weight, this jacket does not have any zippered pockets, only elastic lined open pockets.

If you are headed on a light and fast climbing expedition, this the jacket to take. It is surprisingly warm for being so thin and light, and fits well under any kind of shell. Even though this is a very thin insulated layer, it does not breathe very well.

Compressibility & Weight

The Montbell U.L. (Ultra-Light) Thermawrap jacket is in fact the lightest jacket in this review, weighing only 7.5 ounces. This jacket packs into a stuff sack, which is an awesome feature, but the stuff sack is not connected to the jacket and really easy to lose, especially since there is no zippered pocket to keep the sack in for easy access.

Comfort & Coziness

This jacket has no zippered pockets, which ultimately makes it lighter, and lightness is this jacket's best feature. However the things that are usually keep in the pockets of jackets such as chap stick, car keys, etc, have no secure place. Most of the time this isn't a big deal since this jacket works so well as a mid-layer, and a shell usually has zippered pockets, but out testers did miss the zippers.


Made from 15 Denier Ballistic Airlight Nylon, we found this jacket to be fairly durable and abrasion resistant.

Water Resistance

The new 2013 edition of this jacket uses a new insulation, hydro-phobic EXCELOFT and has a DWR treated exterior as well as a DWR treated zipper.

Style & Fit

This jacket has a slim fit and is form fitting. This is one of the reasons it makes an excellent mid-layer, because it does not add any extra bulk. It still has a very technical look, and is not particularly stylish, but it doesn't look bad if worn in day-to-day life.

Best Application

This is the ultimate jacket to use for the light and fast climber or hiker. If weight is a major concern, then this jacket is the warmest layer you could bring for only 7.5 ounces.


As one of the most inexpensive jackets in this review, the Thermawrap jacket is a great deal, only the Sherpa Vajra and the Columbia Kaleidaslope II Jacket - Women's are cheaper. It is durable, functional, and very high quality for the price. This jacket does skimp on some of the more luxurious features such as zippered pockets, interior pockets, and soft fleece material around the chin, but the basic design keeps the price and the weight down, which are both plusses. For the price you get a very basic but light and functional insulated layer.
