What is the Nova II?

The Nova II is a lightweight, easily compressible synthetically insulated sleeping bag that is ideal for 3-season trekking and mountain adventures. It's incredibly comfortable and spacious and, due to its innovative construction, offers great all round protection and warmth. 

What is the Nova II made of?

Insulation: Featuring Polarloft insulation, the Nova II will provide a good nights sleep down to -3°C.  Polarloft strikes the perfect balance between warmth, comfort and durability. The benefit of a synthetically insulated bag is that the sleeping bag will perform almost exactly the same when wet as when dry, whereas down will lose the majority of its warmth. It won't pack down as small, however for those who are out in all conditions, the Nova II is the ideal choice.

Fabrics: Protecting all of that insulation in Helium 20; this fabric uses tightly woven 20D Nylon yarns to make a fibre-proof fabric. It's soft to the touch, breathable and only weighs 42g/m². The inner of the bag is made up of Supersoft 30 which provides superb next to skin comfort, durability, breathability and only weight 49g/m².

What is the construction used in the Nova II?

The Nova series uses a type of construction called Keystone Shingle construction. Keystone Shingle construction offers the greatest warmth for the minimum weight. Firstly the baffles run from head to toe in the bag, rather than side to side. Internally, overlapping layers of insulation are positioned at right angles to the sleeping bag plane, running outwards from a central apex. This minimises cold spots, offers excellent warmth and creates excellent loft and comfort. For efficiency, the underside of the bag makes use of offset layer construction. 

What are the features?

The Nova features a full-length zip baffle, an integrated collar with lode lock closure and is supplied with a lightweight compression sack for easy storage. 

How does the Nova II fit?

The Nova falls into Mountain Equipments 'Mountain Fit' fit block which is a semi-tapered mummy profile that is both spacious whilst retaining warmth. The hood and foot-box are both anatomically shaped for comfort and thermal efficiency. 


The Nova II is the ideal bag for the adventurer looking for a good balance between weight, warmth and wiggle room - but will also suit well on warmer, summery mountain trips.

Care & Advice

How warm a sleeping bag do you really need? We’ve tried to help you by grouping our sleeping bags by their recognised comfort ratings. These are the ratings supplied by the brands that indicate the temperature at which you will remain comfortable whilst sleeping on a good insulated sleep mat. After all, comfortable is what you want to be when it’s cold and wet outside and you’re all tucked up in your nice warm sleeping bag.

We always recommend that you choose your bag according to the coldest conditions you will experience; you can always unzip a bag if it is too warm, but trying to sleep when you’re too cold is just miserable. Bear in mind that that we are all individuals and we all feel the cold differently, and that our own resistance will fluctuate depending a whole load of factors including how much we have eaten, whether we have consumed alcohol, whether we need a wee or what kind of mood we are in!

Sleeping bags do not generate heat they only trap the heat we produce so it is vital that you get into your bag when you are giving off warmth, don’t go to bed when you are cold, have a hot meal or a hot drink or do some brisk exercise to get you nicely warmed up.

Traditionally sleeping bag manufacturers provided their own temperature ratings based on their experience, the products intended end use and the perceived environment. But each brand tested their bags in different ways and it was hard to find a fair comparison between models. So, in 2005 a European standard for sleeping bag temperature ratings, EN 13537, was introduced to give consumers a comparable guide to sleeping bag performance across a range of brands and models. The ratings have four different temperature ratings to give you an indication of the bags performance.

Upper limit: This is the highest temperature at which an average male should experience a comfortable night’s sleep.

Comfort: This is the temperature at which an average female should experience a comfortable night’s sleep. On average women sleep colder than men so this rating is some degrees above the ‘comfort lower limit’ for a man.

Comfort lower limit:  This is the lowest temperature at which an average male should experience a comfortable night’s sleep whilst lying in a curled-up body position. This used to be known as the comfort rating.

Extreme: This is a survival rating where the user is likely to suffer health damage such as Hypothermia. It should be treated with the utmost caution and not be relied on for general use.

However, the EN 13537 European Standard does not apply to down filled sleeping bags with a fill weight of more than 800g; for those bags you will have to rely on the manufacturer's experience and technical expertise, which is often more accurate!

Most reputable brands still use their own rating system alongside EN 13537, for instance the M.E “Good Night’s Sleep” and Rab’s “Sleep Limit”. These ratings are often the most accurate guide to the overall performance of a bag being used by an average outdoor enthusiast. They are based on years of expedition heritage, field trials, technological experience, and constant feedback.

But please bear in mind that all ratings are only a guide and, as mentioned earlier, there are a huge range of factors that can affect your comfort, if you are just not sure it is always wise to go for a warmer model.

The biggest difference you can make to your overall comfort is to use an efficiently insulated sleeping mat. Once you get inside your sleeping bag you instantly compress all the filling beneath you, greatly reducing its efficiency. The use of a quality sleep mat will ensure you are properly insulated from the cold ground and you will of course be a lot more comfortable. Your sleeping bag is only as good as the mat that’s beneath it; we recommend EXPED, ThermaRest or Multimat sleeping mats for comfort and insulation.

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.
