Made from Stratofiber insulation, which is a type of microfiber, you will enjoy a soft, lofty sleeping space, made of down, which is one of the best fabrics that can be used in a sleeping bag. The Stratofiber insulation is breathable, so you will not have to worry about feeling damp in your sleeping bag.

Your new sleeping bag is waterproof, making it effortless to travel with, and the parts of it that are not completely waterproof are given a treatment called Durable Water Repellent. Another great thing about this sleeping bag is that it is made for three season camping, so you can use it many times through the year! Consider the many features this sleeping bag has to offer by looking at the various key factors that this sleeping bag includes.



The Nemo sleeping bag comes in a beautiful aluminum color which you can only get in a double size. The shipping weight is approximate 6.3 pounds, with the actual bag weighing about 6 pounds. This tells you that the manufacturers have utilized light packaging to ease the burden of shipping and cut down on costs.

Most users opt to buy the air sleeping pad by the same manufacturers alongside the sleeping bag. If you are interested, you will just have to purchase the pad as a separate item. This will set you back approx. $220.

Design & Durability

The Nemo Mezzo Loft Duo is designed for two campers who seek respite from a long day of hiking and other outdoor activities. It is made with dual zippers, one for each side of the sleeping bag, and is made to allow sleeping pads, which are sold separately, for extra comfort.

You can use two 25 inch sleeping pads, or one 50 inch sleeping pads to fit the Mezzo. The sleeping pads are an extra comfort, used for those who like to have the comforts of home, or have back issues. The pads also help to keep the sleeping bag in one spot, in case you shift around in your sleep.

The Mezzo is waterproof for the most part, and the sections that are not, such as the cotton bag that holds the sleeping bag, and the feet of the bag, are given a treatment of Durable Water Repellent, which shuns water but does not prevent it from dampening your sleeping bag.

It is made with Stratofiber microfiber insulation that assures you a soft and lofty sleeping spot that is also made with down comforting. Down gives you the best type of insulation, as it keeps warm air inside, prevents cold air from getting in, and keeps you dry all night long.

The Mezzo Duo sleeping bag comes in the color of Aluminum, which has minor gray and green colors to accent it. Nemo is known for its crazy and bright colors that will surely make you notice their products! Many think it is a breath of fresh air to see new, bold designs and colors that you would not normally see with camping gear. You will not see an average camouflage design from this company!

Size and Weight

Keep in mind that this sleeping bag sleeps two campers, so it is going to be heavier and bigger than your standard sleeping bag. For example, this particular sleeping bag weighs in at 8.05 pounds, which is pretty standard for a dual sleeping bag. If you plan on camping in one area and staying there for the duration of your camping trip, then weight should not be too much of an issue for you.

However, if you are camping, maybe in the mountains, in different spots each night while on a hiking trip, you may want to consider weight distribution between the two campers. This will lighten the load for one person and prevent early fatigue from setting in from excess gear weight. Other than that, you should be comfortable and warm with over 2 pounds of filling made to keep you cozy. Nemo definitely has you in mind when it comes to using materials that provide comfort as well as a quality product.


The Nemo Mezzo Loft Duo sleeping bag makes you feel warm and cozy alongside your camping partner without making you feel claustrophobic. Since it is made for two people, rather than having a hood that cinches around your face, you have a draft collar that keeps your head warm through the night. It also includes sleeves for your pillow! For extra comfort, look into the Nemo Fillo Luxury Pillows. They are said to be top notch!

While you are overall protected from water because of the waterproof material of your sleeping bag, you should still be aware because the feet of the sleeping bag are not waterproof, and the carrying bag that it comes in is made of cotton, which is not waterproof at all. The bottom is not waterproof because there is a sleeve there for the sleeping pads, if you choose to add them to your camping gear. For the most part, you will be able to enjoy this sleeping bag out in the elements without worry.

Temperature rating

This sleeping bag is one made for three seasons, meaning spring, summer and fall. The temperature rating for this product is 30 degrees Fahrenheit, so it will work to that temperature, but falling below that, you will not be protected from the weather. It is not for use in extreme winter camping, or any time after the fall, where temperatures get in the low digits at night.

However, you should keep in mind that the temperature rating is just a base estimate and that you cannot fully rely on the information when you are out camping. Always carry extra clothing in case it gets cold at night and the sleeping bag cannot shield you from it. Users have raised a concern that even at around 37 degrees Fahrenheit, the Nemo mezzo loft duo can leave you freezing, despite its 30 degrees rating.

Unique Features

The Stratofiber microfiber insulation in this sleeping bag is made from a polyester staple fiber that is used by Nemo in their sleeping bags to keep you warm and comfortable. The construction of the insulation is made to fit one layer onto the other, without allowing gaps up air that let in the cold weather. The design is made so that the gaps are closed and you keep in the warmth.

Using down is a great way to not only keep in the warmth and block the cold air, but it lasts a long time. You simply cannot go wrong with down filling. It is known to give more warmth and comfort than any other type of insulation material. Nemo definitely got it right with their materials, as well as cool designs.

The sleeping bag is overall water resistant, so you do not have to worry about it getting wet, or waiting for it to dry out. Most items from Nemo also go through a Durable Water Repellent treatment before hitting the shelves.

Also, the dual zippers are a great idea when it comes to this type of sleeping bag. It allows both campers to rest without disturbing the others, and there is no feeling of claustrophobia while inside of it. There is an integrated blanket fold that acts like a comforter that folds back so you can control the temperature inside of your sleeping bag. There are box baffles that keep cold air out, and it includes a high loft, and a cool, fresh design that makes camping seem fun again!
