Compressibility
The North Face Tephora takes a little more than average effort to compress than other bags in this category. Its compressed size is also the largest compared to other bags in this category, including ones that are warmer and loftier.  

Warmth
While users generally found the Tephora warm in the mid to high 30s, users did not find it warm when temperatures fell to the low 30s and into the high 20s. It is a generous fitting bag subsequently resulting in more draft, and has only a 550 fill (even if it uses ProDown™ to repel moisture, dry faster and improve loft) that may be insufficient for a bag rated to 20 degrees. In addition, the North Face Tephora 20 features an anti-compression bottom layer composed of Heatseeker^TM eco synthetic insulation that, although comfortable, did not seem to add as much warmth as down would otherwise. 

Features
The North Face Tephora 20 is a women-specific sleeping bag, featuring a generous fit. The Tephora has a draft collar and a shaped hood that I found came across the forehead too low, making for an overly restricted hood. The vaulted footbox did add great space for the feet and contains additional insulation in this area (as well as in the chest area) that helped eliminate cold spots. Although the regular sized bag is suitable for heights up to 5’6” two users of this height (myself included) found it short (compared to Therm-a-Rest’s regular sized bag also suitable for heights up to 5’6” but which was more roomy).

The 2-way zipper has an insulated draft tube and allows users to adjust for ventilation (which would be more useful in warmer climates than existed during our testing period). Aesthetically, the Tephora 20 comes in an attractive blue color that users appreciated. Functionally, it also comes in two sizes, both offering a left- and right-handed zipper (although many manufacturers offer both zipper-side options, they do not all offer them in all available sleeping bag sizes). 

The Tephora 20 also has a flap lid inside pocket that, in theory, would make retrieving items easier than having to unzip a zippered pocket. However, I occasionally found my hand snagging in the flap as I moved inside the bag, which was quite annoying. 

Overall Comfort
Users reported the Tephora 20  to be a soft and cushiony bag that was roomy if not as well tailored to women’s bodies as other women-specific bags in the category, and ultimately not as warm for cold weather camping.

Durability
The North Face Tephora 20 showed no signs of wear and tear during the testing phase and there is no indication that problems with durability would arise.
