【Car Camping】Comfortable sleep during fall and winter! The reason for combining a sleeping bag + inner fleece
Wrapped in crisp air and tranquility, camping or car camping from autumn to winter is a truly relaxing and special time. If you can sleep warm without worrying about the night chill, that experience will be even more enriching. So what should you bring ── the new Bears Rock autumn set seems to be a great option.
Warmth is not just about "being confined"!
The "-6℃ envelope-type sleeping bag" combined with the "Kurumu Inner Fleece" creates a "Warmth-Wrap Set." The background of this set is a unique design philosophy called "Sleeping Bags that Circulate Warmth." Generally, sleeping bags are thought to block outside cold air and retain internal warmth.
Bears Rock has taken this a step further by focusing on how the warmth generated from the sleeper's body is "transferred." It not only keeps warm air around the body but also conveys that warmth from the inner fabric to the padding, allowing for the comforting sensation of warmth circulating throughout the entire sleeping bag.

It not only keeps warm air around the body but also conveys that warmth from the inner fabric to the padding, allowing for the comforting sensation of warmth circulating throughout the entire sleeping bag.
One aspect to note is the ingenuity applied to the inner fabric that touches the skin. The inner fabric of sleeping bags is sometimes made of high-density materials for durability, but if it does not allow air to circulate easily, warm air tends to become trapped between the skin and the fabric.
To address this, Bears Rock developed an inner fabric that maintains strength to withstand movements like turning over while also being breathable. This design transmits warmth from body temperature to the padding, wrapping the body in warm air contained within the plush padding. Furthermore, since it's the first layer that touches the skin, they also pursued a soft and relaxing texture. The padding employs a "double quilted structure" with hollow synthetic fibers layered in two layers, effectively storing warm air.

Camping from fall to winter can mean varying nighttime chill depending on the day and location. In this set, the "-6℃ envelope-type sleeping bag" is paired with the "Kurumu Inner Fleece." The fleece has properties that allow air to pass through, enabling the design to "transmit warmth to the padding" while adding extra warmth. Since the fleece is soft against the skin, it mitigates the chilly sensation upon entering the sleeping bag, providing a cocoon-like feeling. The fabric stretches horizontally, making it easy to move even when layered.
On days when you want added warmth, insert the Kurumu inside the sleeping bag; on days when the sleeping bag is comfortable on its own, simply remove it—this simple adjustment of adding or removing one piece allows you to tailor warmth according to temperature and location. This set, thoughtfully combining the roles of both the sleeping bag and fleece, ensures a comfortable sleep during autumn and winter.
