What is the Protect Fiber Bag?

The Protect is an innovative bag which uses the legendary Ajungilak synthetic insulation to provide warmth in extreme temperatures. It moves away from the standard design with a zip at the side and puts it on the top, slap bang in the centre.

What is it made of?

Outer fabric: A tough nylon outer fabric encapsulates the legendary Ajungilak insulation and features a durable water repellent coating to deal with condensation general moisture. Mammut have made this fabric feel as soft as your duvet at home, yet far, far tougher for rugged outdoor use. 

Insulation: The legendary Ajungilak insulation is used throughout the bag. Ajungilak have been creating insulation since 1855, so they're pretty good at what they do. This insulation is made entirely from synthetic materials, meaning if it gets wet it'll still provide warmth; useful if you accidentally spill a drink over yourself (not speaking from experience, honest). 

Inner: The lining fabric has been designed, much like the outer, to feel like a duvet you'd have at home, creating a 'homely' feeling and therefore allowing you to sleep better. 

What are the features?

Probably the most unique feature is the centre zip. Rather than your standard side zip which is generally difficult to find and undo in the dark, Mammut's centre zip never snags and can easily be undone no matter what position you're in. The centre zip also massively improves ventilation and allows you to either unzip from the bottom to ventilate your legs, or from the top for greater heat dissipation. A magnet at the top of the zip seals the bag up to your neck and is super easy to undo, just give it a pull. There's also a drawcord to compress the hood and insulation collar for greater warmth.

Another unique feature is the inclusion of a sleep mask and earplugs, allowing you to get the best night sleep possible no matter what's going on around you. A specific fabric is used in the hood which is quieter than your average fabric, further reducing noise if you're not using the earplugs. Even if you're not using the mask or plugs, they can be neatly stashed away in the internal pocket, keeping them within arms reach. This is also a great place to pop your phone to prevent it losing battery in cold conditions. You've even got two zips for your arms so you can go about your usual morning duties whilst still wrapped up in your sleeping bag. 

How does it fit?

It features what Mammut call a 'restorative' fit, meaning there's more than enough room to comfortably move about during the night, yet not so much that it takes hours to warm up. A cleverly shaped footbox allows your feet to sit in their natural position during the night, preventing it compressing the insulation.

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.

Emily - May 2020

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!
