The performance cut of the Superlight makes it feel tailor fit without being constricted. The internal space is fairly typical of most mummy sacks; the excess weight was clearly cut by the design and the materials because the comfort is exceptional. Imagine sleeping in a warm fluffy cloud and that will give you a good idea of how it feels.

The performance cut still allows for moderate movement.

-    Shell: Water-resistant lightweight ripstop nylon
-    Lining: Nylon taffeta

-    800-fill ProDown is water resistant 
-    Performance Mummy Cut
-    Cinch-cord on hood to seal in heat
-    Semi-continuous baffles minimize weight
-    Stuff sack and mesh sack included
-    Down-filled neck collar
-    Centre half-zipper
-    Water-resistant Neovant Air on head and footbox

The draw cord on the hood pulls tight to keep the cold out, where it belongs.

Zipper garage stows away nicely without being inaccessible.

The mesh storage bag protects the down loft when the bag is not in use.

In addition to the features listed, the North Face website claims that there is an internal pocket to store small items. In my attempt to find it, I turned the whole bag inside out, but to no avail. My suspicion is that there was a zippered pocket in previous versions, and their website has not been adjusted accordingly.

While there is no pocket to show, turning the bag inside out does show off the neck collar baffles.

For a sleeping bag that focuses so ardently on minimizing weight and size, I was surprised to note that there was no compression sack included. I put the Superlight in a compression sack I owned for comparison sake and it certainly makes a difference. The stuff sack provided is barely more than a bit of nylon stitched together and I would not count on it for any kind of protection (as a down bag it must be kept dry to be useful).

A compression sack will save you a few inches in both height and width.

I tested this bag on several outtings one of which was was supposed to drop to -4°C in the evening, but I was so comfortable that I was suspicious of the actual temperature outside until I got up in the morning and discovered that it was indeed quite frigid. Personally, I have a fairly weak internal furnace, so anyone with a more robust internal system will have a good night’s sleep at -9°C or colder.

Overall, the Superlight is marvellously light, warm, and compressible. I was disappointed that there was no compression sack included, as it seems a bit cheap for a sleeping bag that costs this much. The Superlight is slightly more expensive than the competition; however, it is also slightly lighter which explains the difference in price. If warmth and weight are of the utmost importance, this is the best bag on market for this temperature range.
