Japanese outdoor equipment manufacturer Campal Japan has announced that it will release the Apollon T/C, a large tunnel-shaped tent, in late November. The Apollon T/C is a T/C (technical cotton) version of the already marketed Apollon, which is made of polyester material, and is designed to be more comfortable for hot summer and winter camping in Japan. On the other hand, the Apollon T/C does not come with the Apollon inner tent. In addition, the Apollon T/C is heavier and more expensive than the Apollon. In Japan, demand for tunnel-type tents is growing, and the company is thought to be expanding its product line in response to this.
