What type of the sleeping bag is this – who is it for
This NEMO Women’s Cleo 15 is a backpacking bag with a great temperature rating that will protect you in any conditions in a 3-season use and even more than that. It is a mummy-style bag as you realize from the picture so the size and shape are what you would expect from such a type, I mean this is a snug design.
You will notice that baffles are longitudinal and there is a reason for that; they use such a design so that the heat moves through the insulation along the bag so that you have a better temperature balance in particular in the feet zone which is usually the most critical. I have just returned from the Alps where I have experienced this in my own bag.
This is a women-specific design and they build the bag in two sizes R and L, see more in the specifications below. Note that they also have a corresponding model for men which they call NEMO Ramsey 15 sleeping bag.
Materials & construction
This is a bag with several useful bonuses, so let me go through them. The hood is quite large but you can cinch it down completely on cold nights. The fabric is really soft and it is with a coating to protect the fill from the moisture.
The temperature rating
You have the temperature rating 15 F (-9 C) so this is a warm bag suitable even for rather low temperatures. As usual, for a comfort, I would add some 10 degrees up, so I see it as a very good 3-season bag.
This insulation is achieved by using a 100% Responsible Down Standard (RDS) Certified down which is traceable and they claim it ensures a “humane treatment throughout the supply chain”. This is the 650 Nikwax-treated down which provides the water-repellency. So it remains dry longer and it also dries faster if it becomes wet, than an untreated down.
The thermo gills
The mentioned temperature rating is such that the bag may look too warm for a warmer environment. But you have two-way main zippers for ventilation and in addition, it comes with integrated thermo-gills. If you are puzzled by this, just to know – this is about two short zippers which you have on the chest, they are visible in the picture below. So you can unzip them and get some fresh air if you feel warm, while still keeping the main zipper closed. This should be good enough to regulate the temperature up to 20 degrees or so.
The Blanket Fold
This is a small extension which you see under the opening, see the picture above. You can use it during cold nights to prevent drafts, or you can push it out if you feel warm.
Waterproof footbox & hood
In the feet area and on the top of the hood, they use a different fabric, 40D nylon ripstop OSMO DWR which is waterproof but breathable. This is a great addition because of the condensation on the walls, those are the parts of the bag that are most frequently in contact with the walls.
The compression stuff sack
I appreciate the fact that they give a compression stuff sack here, see the picture below. So you have compression straps on it and can reduce the bag considerably. Its packed size is great, only (L x D) 12 x 7.5 in (30 x 19 cm). But note that a down bag should not be stored like that for an extended period of time, and yes, they provide a cotton storage bag as well, so use it for the storage at home

Final thoughts, rating, pros & cons
In the summary of this Nemo Women’s Cleo 15-Degree Down Mummy Sleeping Bag review, I can only stress again that this is a top-quality item from a renown brand that is at the forefront in this industry. So although the price is high, you know what you are buying and this item is worth the investment.
On the other hand, if you check the models given in the comparison table above, you realize it is roughly the same price as the Marmot’s bag, but it is only half the price of the Big Agnes’ bag. Now you realize why it is important to make comparisons like this, it put the things into perspective and you can make an informed choice. All in all, I have no doubt, this bag is a reliable backpacking and hiking item.
