Mountain Equipment Classic 500 Sleeping Bag Information

Season : 2020W C OFFER

Brand : Mountain Equipment

Code : 002084-01320

The Classic 500 by Mountain Equipment uses a lightweight yet durable 40D outer fabric to encompass 433g of pure duck down. This outer fabric is designed to meet the demands of climbers, mountaineers, walkers and just about anyone requiring a small pack size and low weight. Thanks to it's densely woven design, the fabric is completely down proof, minimising the amount of down that will escape over time and in turn maximising durability, tear resistance and breathability.

Using a super high quality 700 fill power duck down, the classic 500 will pack up smaller than a similar bag with an inferior quality down and will be warmer for the weight too. What makes Mountain Equipments down different to others however is that they became one of the first outdoor brands to introduce independant autiding of their down supply. This provides the ability for M.E to trace 100% of their down, allowing them to only use responsibly sourced down. This is not only better for the birds and the environment, but also means the down inside the product is a higher quality. This premium duck down is from the very cold North East of China and is collected from ducks that live a truly free-range existence. The birds are sold when they no longer produce eggs or when the market price for eggs drops below the break-even point. The birds are normally around 700 days old when slaughtered, they are then plucked and the down is shipped to the processing plant for cleaning and grading. Because these ducks are older and have lived in a free-range environment and a cold climate the down they produce is of an exceptionally high quality. All Mountain Equipment bags adhere to the Down Codex, a scheme that was developed to ensure that both animal welfare and down quality were put firmly at the heart of each and every one of M.E's down products. 

Mountain Equipment's bag's are very unique in a number of ways. One is the way they optimise their heat efficiency by changing the layout of the baffles. By slanting the baffles throughout the entire main body of the bag, it allows all unused space is eliminated which lowers the weight. Further weight is then saved by using their stitch through construction. This method also spreads the down out more evenly across the top, side and bottom of the bag, providing a warmer experience and a longer lifespan. The overall down distribution also allows M.E to favour certain parts of the bag to offer the highest warmth for the weight. Slightly favouring the underside of the bag, the underside of the hood and the foot piece, M.E can provide a warmer bag due to their experience of where most heat is lost. Offering more/less down in certain areas also improves the comfort, mainly in the collar area and around the head. 

Each one of their sleeping bags features a unique foot piece section depending on the use of the bag. In this case the bag is designed to be as light and as compressible as possible. The Classic 500 features a 2 baffle foot piece with a little more room than your standard sleeping bag to suit long durations in cold weather. 

A high percentage of your body heat is lost through your head so Mountain Equipment have developed their hood which uses 5 baffles to create a truly anatomical shape to surround your head with luxurious warmth. To further optimise insulation M.E have developed the Gemini System that has two overlapping anti-snag draft tubes and a fully integrated neck collar. 

The Classic 500 is a spacious, comfortable and versatile bag, ideal for summer, autumn and spring use in temperature climates. The waterproof stuff sack keeps the bag safe when out and about, while the included storage cube allows you to safely store the bag when not in use.

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.
