The Carinthia Tropen is a lightweight and very breathable sleeping bag for summer and indoor use. Equipped with a mosquito net to shield you from bugs. It's difficult to imagine a better summer sleeping bag; this is top-tier military quality for the demanding user! Issued by the FDF for peacekeeping missions.

• Lower Limit: 5.1°C / 41.2°F
• Weight 1100 g / 2.4 lbs (Medium)
• Military-grade materials
• Integrated mosquito net

Differing from Carinthia's Defence series, the Tropen has a breathable Shelltrans outer layer. This keeps you comfortable when sleeping in warm weather. Use a tarp or tent to shield you from rain.

Comes with a compression bag that allows various packing options.

Tropen shape and features

The mummy shape: Here, the criteria of stuff size, weight, and warmth are most important. The tapered foot section reduces weight and stuff size. However, the main advantage is that there is increasingly less internal volume to keep warm from the knee downwards. The foot section should not be so small that the feet cause insulation layers 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 body's true proportions.

Two-way zipper: All Carinthia military sleeping bags are equipped with a two-way zipper. The glider on the top does not lock, allowing a quick step out if necessary (in case of alarm, for example). The bottom glider does lock and can be opened for ventilation.

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 outer shell fits loosely over the bag innards, providing an extra insulating layer of air. That also eliminates heat loss due to seams combining the shell with the fillings. Overall, this feature enhances the bag's performance considerably!

Combine two bags, get three

By layering the Carinthia Defence 4 inside the Carinthia Tropen, you get a combination that works in extremely freezing temperatures. These two make an excellent pair for users in intermediate weather areas: use the breathable Tropen in the summer, switch to the Defence 4 in fall, and bring along both into the heart of winter.

This combo is endorsed by Carinthia and zippers of these bags are positioned differently to minimize heat loss. They can be packed together into the Defence 4 compression bag for ease of carrying. The Tropen goes inside the Defence 4.

Materials

• Shelltrans outer shell and lining - a soft to the skin ripstop reinforced, highly breathable polyamide with excellent moisture-wicking capabilities.
• Thermoflect, a very thin, very lightweight aluminum material that reflects body heat. Thermoflect raises the sleeping bag's heat-retaining capacity by about 11 %.
• G-Loft filling - Carinthia's own, in-house "hollow-fiber", made in Austria. Highly compressible, excellent weight-insulation ratio and also moisture resistant, meaning that it will work even under long-term use in damp conditions.
• Tropen uses single layered, lightweight G-Loft filling. In this lightweight design, the outer shell is loosely attached to the bag. The G-LOFT Plus 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.

Carinthia sleeping bags are not entirely PFC-free, but do have the Oeko-Tex certificate, Standard 100.

Temperature specifications

Tested according to ISO 23537 / EN 13537, where "Comfort" represents a standard female sleeping comfortably in a relaxed position, and "Lower Limit" is where a standard male can sleep for eight hours without waking in a curled position. "Extreme" is not relevant to the common user: it's the temperature where a standard female can survive for six hours without dying of hypothermia.

• Comfort: 9.4 °C / 48.9 °F
• Lower Limit: 5.1 °C / 41.2 °F
• Extreme: -7.9 °C / 17.8 °F

The values are comparable between manufacturers who conform to the standard. Note that some manufacturers label the Comfort as "Female Comfort," and the Lower Limit value may be presented as "Comfort Limit."

If you're a "warm sleeper," look at the Lower Limit figure when choosing a suitable sleeping bag. If you get cold easily, look at the Comfort rating instead. Quite simple.
