I am a hammock specialist manufacturer from overseas. I purchased this through personal import and used it once for a day camp. Apparently, hammocks don't really suit my constitution, so I'd like to sell it. It's not available in Japan, so if you're looking for one, take this opportunity. This manufacturer allows you to choose the color of the hammock body and underquilt, and I chose a rugged olive green that blends in with the forest (it looks brighter in the image, but it's a deep, dark green). Also, the suspension system is optional, and I chose a high-grade suspension system with Dyneema cord and lightweight hooks, making it easy to set up. This is a great set of the hammock body + winter underquilt (for extreme winter conditions). The underquilt is also from the same manufacturer and matches the color. The hammock bottom has a double bottom, allowing you to insert a mat, etc. This is a so-called bridge-type hammock with two spreader bars included, making it a flat-sleeping type of hammock like a Haven Tent. A storage case for the spreader bars is also included as a bonus. Normally, this set would cost nearly 100,000 yen including shipping if you were to import it yourself, so I think it's a good deal.
