This construction ensures reserve warmth for cool, foggy nights. In warmer weather, the bottom part of the two-way zipper can be opened for ventilation. The hood is equipped with a mosquito net which can be folded out of the flap if required (the mosquito net is in the front part of the bag and stored behind the flap with press studs). The net can easily be attached around the hood by means of the small zipper. The zipper is non-snagging so that you can always get in and out quickly and easily. Features: 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. 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. 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. SINGLE-LAYER NOT QUILTED WITH SHELL In this lightweight design, the outer shell is loosely attached to the bag. The G-LOFT ISO+ filling is quilted to an insulating scrim. As a result, an additional air pocket is formed between the quilted insulation layer and the shell, yet no cold seams can occur. 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. COMBINABLE SLEEPING BAG SYSTEM Some of our sleeping bags can be combined to a sleeping bag system. Such a system can be used as a 4 Season Sleeping Bag and allows you to carry only the weight and the bulk necessary for the prevailing temperatures. MOSQUITO NET It has one!
