sleeping bag you’ll just love – here’s how to sell its finer points straight from the horse’s mouth…
ur patented self-closing neck baffle combined with a construction that involves both fibre and down makes this sleeping bag a unique product. The sleeping bag is a two- layer construction with fibre as the outside layer, for optimal protection against the elements; thus protecting the warm down filling from the damp inside the tent and providing the maximum comfort. The inner layer closest to your body is down filled.

AirLock self closing neck baffle.
This is a big anatomically down filled baffle that keeps the warm air inside the bag and prevents cold air of getting in - and it’s done without any draw cords. The baffles are filled with 90g down.
The outermost layer of the sleeping bag, known as the shell, provides your primary defence against rain, wind, sleet and other undesirable conditions. To achieve this, the AirLock has a very strong but lightweight 310T nylon ripstop with a water repellent coating. This fabric is both very durable and very breathable so damp can escape the bag.
The meat of the sleeping bag is in its insulation, the filling between the shell and the person that isolates and creates a pocket of warmth, keeping the user’s temperature at a sleep-worthy constant. For the best warmth to weight ratio, nothing beats natural down from ducks or geese. There are a number of disadvantages to down filling, though. If down gets wet, it loses its

Top Tips
• Air out your bag the morning after use, in the sun if possible. Dew and perspiration can interfere with the warmth retaining properties of the insulation.
• Store your bag either by folding it loosely or letting it hang in your closet. If it is too tightly packed, the insulation fibres may deteriorate.
• Straight out of the compression sack, your sleeping bag may need some time to expand, particularly if it is a bag with down fill. Fluff it and spread it out so that it reaches your desired loft.
• If you feel that your feet won’t be sufficiently insulated, stash the bottom of your sleeping bag in your backpack for added protection.
warmth-providing quality and becomes twice as heavy. Worse, it takes quite some time for down to finally dry out. That is why the AirLock has a layer of down closest to the body and a layer of synthetic fibres on the outside. The synthetic fibres will not absorb humidity and are able to insulate also in damp/wet conditions. Lastly, sleeping bags come with an interior lining, the layer that makes contact with your body and clothes and should be both smooth and soft to touch and won’t catch on your clothing. But it should also be very breathable so moisture

from your body can escape. The AirLock lining fabric is both soft and smooth but actually more importantly, it is highly breathable. During the night the average person will sweat 0.5 to 1.0 litre, and you don’t want this to stay in your sleeping bag. So with a lining fabric that has slightly better breathability than the shell layer the sweat/damp will be forced to escape the sleeping bag by pressure.
The shell is bigger than the lining which means that the insulation is not compressed when you move inside the bag.
