What is the Ultralite Pro 300?

The Ultralite Pro 300 is a warm, compressible and highly versatile synthetically insulated sleeping bag for all year round use in a wide range of conditions. Vango's clever construction techniques increase the warmth of the bag without adding high amounts of weight. 

What is it made from?

Insulation: Vango use a lightweight, compressible and super warm synthetic insulation called 4T inside the bag; this allows you to use the bag in a wide range of conditions (wet or dry) without the insulation losing high amounts of warmth. Another benefit of 4T is that unlike some other synthetic insulations, 4T traps air in small channels within the fabric, meaning it can compress down smaller and will weigh less than many alternatives. 

Outer fabric: Surrounding this toasty insulation is a Polair Active Shell fabric. This 20D nylon fabric offers durability and weather resistance, protecting you and the insulation from light moisture and general wear and tear. 

What are the features?

The most unique feature of the Ultralite is its Thermal Embrace System. This system uses pieces of elastic which are sewn into the inner fabric, allowing the bag to gently conform to the shape of your body during the night. This increases warmth as there is less dead space inside the bag, but barely adds any weight. Other useful features include zips which are placed in areas where your body is warmest, avoiding valuable heat loss, an internal pocket for a phone or other electronics, a full length two way zip to ventilate and allow easy access in and out, an insulated zip baffle to prevent heat escaping, a 3D hood with a multi-cord closure and a 4-strap compression stuffsack. 


The Ultralite Pro 300 is the ideal bag for those who are out in all weather conditions, all year round. The clever design and multitude of warmth-saving features ensures you're kept warm without the weight penalty.

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.
