※Additional Explanation
Crafted for Japan’s Four-Season Landscape
Japan’s natural beauty invites exploration all year round — from snowy winter forests in Tohoku to crisp autumn hikes in the Japanese Alps. But such conditions require gear that’s as resilient and flexible as the environment itself.
This envelope-type sleeping bag fits that need perfectly. Unlike traditional mummy bags, it offers more room while maintaining thermal insulation. Its multifunctionality is ideal for Japanese lifestyles — where space-saving, efficiency, and versatility are valued. Whether you’re car camping at Lake Biwa or preparing an earthquake emergency kit, this sleeping bag offers peace of mind in any season.
It’s more than gear — it’s comfort, warmth, and readiness, all wrapped in a packable, durable design.
