Synthetic insulation is the workhorse of the insulation world. It’s not necessarily the lightest option nor always seen as the most glamorous, but it is without question the most reliable, resilient and the most dependable insulation. Made from polyester, synthetic insulation’s low surface energy makes it hydrophobic, and therefore water-shedding. In addition, the fibre’s very low water regain means that little water is absorbed into the fibre even if it adheres to the surface. These factors contribute to synthetic fibres being excellent insulators in wet conditions.
Polarloft®
Our most trusted and longstanding synthetic insulation which strikes the perfect balance of warmth, comfort and durability. Made from fibres of differing diameters: the thicker ones providing durability and loft while the finer fibres provide much of the insulation.
The fit of a sleeping bag is crucial in optimising performance. A well-fitting sleeping bag is not only highly comfortable it also reduces dead air space and maximises thermal efficiency.
Mountain Fit
The foundation of all our fit blocks, this semi-tapered mummy profile combines excellent thermal efficiency and comfort for all-round mountain use.
Fabric technology is advancing all the time and we continually seek out those fabrics that offer the lowest weight, maximum breathability, compressibility and comfort.
Helium™ 20
Weighing just 38g/m2, HELIUM™ 20 uses 20 denier yarns to create a fabric that is compressible, tough, and extremely comfortable. Its densely woven construction ensures the highest levels of downproofing, wind resistance and resistance to heat loss. The new HELIUM™ 20 offers greater handfeel over previous HELIUM™ fabrics as well as reduced seam slippage, resulting in even greater durability than the previous fabric.
Supersoft™ 30
Supersoft™ 30 is our legendary performer chosen for its breathability and durability. Weighing just 49g/m² provides exceptional durability with a soft hand and good breathability.
Baffle structure is crucial to the performance of down sleeping bags. Without it, even the best quality down will not loft and insulate to its full potential. Baffles affect a sleeping bag’s durability, weight, and the migration of down inside them – they are the building blocks from which sleeping bags are made.
Keystone Shingle
A unique method of construction developed by Mountain Equipment which creates an extremely warm sleeping bag that is durable, soft, and with no cold spots. The traditional method of vertical shingle construction is highly effective but can lead to cold spots at either the edge of the bag or at its centre because of the required seaming. Our Keystone shingle foregoes this problem by positioning the warmest part of the bag over the user and reduces cold spots by using a central triangular piece of insulation with vertical shingle at either side. It is used in the top side of the Nova sleeping bags.
Offset Layered Construction
Offset layers are used in the Nova sleeping bags’ undersides. It is a lightweight and relatively simple method of construction where sheets of insulation are laid on top of one another. It gives great all round performance.
Our neck baffles and entry-zip baffles are vital in reducing the ‘chimney effect’ of hot air flowing out of the sleeping bag’s openings, and are also useful in reducing the ‘bellows effect’ of the movement of a restless sleeper pumping warm air from the bag.
Lode Lock™ Collar Closure
Our Lode Lock™ collar closure with its low profile auto-locating closure combines all the advantages of a magnetic fastener with those of a mechanical lock. Rendering the traditional press-stud collar closure practically obsolete, its one handed quick release closure uses two captivated internal magnets to draw the locking mechanism together and ensure that once connected it cannot be accidentally opened. The result is an insulated collar that is more efficient and easier to operate. The collar’s down density is optimised so it moves with the user and contours to the body, while captive and elasticated drawcords ensure easy adjustment.
The head loses a lot of heat and is very sensitive to changes in temperature, making good hood design crucial to the performance of any sleeping bag. A good hood will also keep the neck warm and reduce the ‘chimney effect’ of hot air escaping the body of the sleeping bag.
SC2 Hood
Our most advanced synthetic sleeping bag hood, it has been completely re-engineered to offer improved fit, lower weight, and easier adjustment than previous iterations. Reshaping of the hood has also resulted in reduced seaming, particularly in areas most prone to getting wet. This leads to better water resistance, increased warmth, and reduced weight. Drawcards are now independently adjustable, by one hand if needed and run extremely easily.
Cold feet can spell the end of a comfortable night’s sleep or even the end of an expedition and we have unrivalled experience in designing innovative sleeping bag foot pieces. By controlling the down in a sleeping bag, the foot is kept warmer, and ensuring the foot piece fits perfectly around the lower body is crucial.
Trapezium Baffle / Sharks Toe™ Seamless Footpiece
The footpiece is anatomically shaped, seamless for greater water resistance, and features our often-copied but never-bettered Sharks Toe™ design which allows a foot to sit at the most natural angle for sleeping. All these features ensure that your feet remain warm and comfortable throughout the night.
