【KM4K × CYCLE HATENA】PASS HUNTER BAG ver.5|A Back-to-the-'90s Frame Bag Built for Carrying Your Bike
A special corner frame bag that blends a tribute to 1990s MTB culture with the needs of modern adventure riding.
The PASS HUNTER BAG ver.5 was created through a collaboration between KM4K, a brand rooted in outdoor culture, and Kyoto-based bicycle shop CYCLE HATENA.
Its distinctive triangular shape recalls the mountain bike culture of the 1980s and 1990s, while modern materials and practical features bring it up to date. Designed for rides that go beyond smooth pavement, it is equally at home on gravel detours, forest roads, and bikepacking or camping trips.
Its standout feature is the integrated shoulder pad. When the route requires you to carry your bike, the pad helps reduce pressure on your shoulder, making adventures that involve riding, pushing, and carrying more comfortable.

💬 STAFF REVIEW
This style was popular in the 1980s and 1990s, but for riders like us who regularly head out on gravel rides, it still feels like a genuinely useful piece of gear.
The accessible price and KM4K’s playful patch are the finishing touches that give the bag its distinctive character.
