Say goodbye to restless nights during tropical nights! The summer sleeping bag + moisture-absorbing inner towel feel great
In summer camping, just as much as daytime heat, nighttime heat countermeasures are important. Supporting a good night's sleep on such nights is Bears Rock's "Envelope Sleeping Bag -6℃" and "Kurumin Inner Towel." I want to sleep soundly even on sweaty nights!
Even in the muggy summer camp, you can sleep soundly until morning

During the summer, when temperatures exceed 35°C during the day, campgrounds at higher elevations are recommended for their coolness. If you set up your tent in a place that is less prone to heat and has good ventilation, you can escape the heat and enjoy a comfortable time. If you want to stay even cooler, you should pay attention to your “sleeping arrangements.”
Even on nights when heat and humidity tend to accumulate, with the Bears Rock "Envelope Sleeping Bag -6°C" and "Kurumin Inner Towel," you can maintain coolness and have a comfortable sleep.

The "Envelope Sleeping Bag -6°C" can be fully opened for family sharing.

It has a shape similar to a set of a mattress and a comforter, allowing for easy temperature adjustment. When it’s hot, just open the zipper, and if it’s cold, close it.
The hollow fiber chemical material BR Warm used for the filling is specially designed to lower the internal temperature by about 6°C even when the outside temperature is 25°C. By fully opening the zipper, it quickly transforms into a double-sized comforter measuring 190×150 cm. It maintains a smooth texture whether lying on it or snuggling under it. It is machine washable, so there is no worry about mold due to sweat stains.
The "Envelope Sleeping Bag -6°C," which has a spacious width and does not feel constricting, is also perfect for car camping. It’s ideal for touring, mountain climbing, and emergency preparedness.

The “Kurumin Inner Towel” instantly absorbs sweat

The “Kurumin Inner Towel” is a large microfiber towel measuring 180×75 cm. It is sewn in an envelope shape, allowing it to be used as a sleeping bag liner or as a bath blanket, making it a versatile 2WAY item. You can use it as a cover or lay it down as a mat, and the possibilities depend on your ideas.
It is made of moisture-absorbing material that quickly releases sweat while sleeping. It keeps the surface of your body dry and does not make you feel sticky with sweat.
Even if it gets wet from morning dew or sweat, it dries in about an hour under a well-ventilated tarp, thanks to its quick-dry feature. It is easy to wash even after consecutive camping nights or car naps, and it helps suppress unpleasant odors.
