Sleeping bag DEFENCE 4

The Defence 4 is the most popular and best-selling all-round sleeping bag with excellent weight to stuff size and performance ratio. It is a well-established, treeseason sleeping bag that has proven to be 100% reliable on cold nights both in the wilderness and in snow caves. A protection flap on the outer side of the ziper keeps out wind and wetness. The outer shell is a super-light, highly resistant, microfibre nylon with a fine microporous coating which makes it waterproof. There is a generous draft tube on the inside of the zipper to prevent heat loss at the zipper.

G-LOFT Plus Filling

Manufactured from high-quality bi-component polymers, the structure of G-LOFT insulation is in fact similar in many ways to high-quality goose down. The 3-dimensional crimping ensures maximum resilience and loft

TRIPLE-LAYER SANDWICH CONSTRUCTION WITH LOOSE SHELL

The three G-LOFT Plus insulation layers have offset quilting. The shell is not quilted with the filling, but attached later. This provides an air cushion between the insulation and the shell. With no stitch perforations in the shell, it is relatively water and airtight.

THE MUMMY SHAPE

Here the criteria of stuff size, weight and warmth are most important. The tapered foot section reduces weight and stuff size. The main advantage is, however, that from the knee downwards there is increasingly less internal volume to keep warm. The foot section should not be so small that the feet cause the layers of insulation to poke out. A trapezoidal foot section has proven to be ideal. A wedge shape, declining evenly in width from top to bottom, does not fit the true proportions of the body.

THE TRAPEZOIDAL FOOT SECTION

Experience has shown that the trapezoidal cut provides the ultimate foot space. In a normal sleeping position, the feet do not poke the insulation outward, avoiding cold spots. There is also enough room to store a shoe bag or extra clothing.

THERMOFLECT

Thermoflect increases the heat retention of a sleeping bag by around 11 %. Thermoflect is our solution to heat loss due to body radiation. Thermoflect is an ultra-light, ultra-soft, breathable scrim with the unique ability to reflect body-heat.

DIFFERENTIAL CUT

Even when the sleeper moves about compressing the inner layer of insulation, the sleeping bag’s warmth is retained. Successive insulating layers are cut more generously. This ensures the greatest loft in all areas and in every position. Additional air cushions form between the various layers. Movement inside the sleeping bag creates pressure points, but with our differential cut only the innermost layer is compressed. The outer layers retain their loft and therefore their insulating properties.

TWO WAY ZIPPER

All Carinthia military sleeping bags are equipped with a two way zipper. The glider on the top does not snag, allowing a quick step out if necessary (in case of alert for example). The glider on the down side does stick and can be opened for ventilation.
