What is the Alpine Pro 600?

If you're familiar with Rab's current range of sleeping bags, you may have heard of the Ascent and the Neutrino Endurance; well the Alpine Pro is a mix of the two, combining the brilliant value of the Ascent with the packability and technical fit of the Neutrino. It uses a high quality 650FP hydrophobic duck down and a Pertex Quantum outer fabric to ensure weather resistance in severe conditions.

What is the Alpine Pro made of?

Insulation: Starting with the most vital part of the bag, the insulation.  Rab use a high quality 650 fill power, R.D.S certified, hydrophobic, European duck down; we know there's a lot of info there so let's break it down.  

Fill power: refers to the 'fluffiness' of the down, therefore 1 ounce of this high quality down will fill 650 cubic inches of space when lofted fully. 

R.D.S: stands for Responsible Down Standard, ensuring the down comes from happy birds who haven't been live plucked and have been well cared for. 

Hydrophobic: refers to the coating that is applied to the down to allow it to perform better in damp conditions than untreated down. This coating will also ensure the down is warmer when wet, lofts faster and dries faster than untreated down.  

Outer fabric: Surrounding this high quality insulation is a Pertex Quantum Pro fabric; this fabric is water resistant, breathable, wind resistant and lightweight enough to allow the bag to pack down to a small size when not in use. Although you should never aim to allow a down sleeping bag to get wet, we know condensation and light drizzle are unavoidable, therefore this fabric prevents the down getting wet.  

What is the construction used?

If that wasn't enough of an information overload, Rab store the down in optimised trapezoidal chambers to increase warmth and decrease the likelihood of cold spots. These special shaped chambers allow the down to loft fully after being compressed for extended periods of time. As well as optimised chambers, Rab use “proportionally designed differential cut” which is basically the difference in size between the inner and the outer shell of the sleeping bag. Most inner shells will usually be the same size but the outer shell may need to increase to accommodate a higher weight of down or down of a higher fill power as you progress through a range of bags, for instance, a bag with an 800 fill power will have a roomier outer shell than a bag with a 600 fill power. 

What are the features of the Alpine Pro?

A 3/4 length zip with a baffle behind prevents heat escaping through the zip, while an internal stash pocket stores items such as a phone or headtorch when the batteries need to stay warm. Included with the sleeping bag is a loft bag to store the sleeping bag when not in use, and a compression bag to (you guessed it) compress the bag in your pack when on the move. A 3D internal collar and hood drawcord ensure that all the lovely warm air inside the bag doesn’t escape. The fully insulated collar sits snugly around your shoulders to add an extra layer of protection and insulation in exceptionally cold conditions. The foot section features an angled which provides plenty of space without compressing the down and reducing warmth; no one likes cold feet! 

How does the Alpine Pro fit?

The Alpine Pro features Rab's Mummy Taper fit; this is a slim, body-hugging fit to maximise warmth and pack size. The more space inside a bag that you aren't filling, the colder the bag will be. If you tend to move around a lot in your sleep, you may want to have a look at Rab's Ascent range which features a roomier fit. 


The Alpine Pro is the perfect bag for those not wanting to spend a fortune on a cold weather bag, yet require the performance, pack size and weight to be effective in mountainous environments. The high quality hydrophobic insulation and weather resistant outer fabric ensure protection in the worst conditions, while a re-design in baffle shapes increases warmth even further.

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.
