The color is indigo blue. PLUSONEWORKS is a domestic backcountry rucksack brand developed by FULLMARKS, which imports high-end outdoor items from Northern Europe and other regions. The Shumari 35 is a backpack with a capacity of 35L, as the name suggests. The back and shoulder harness are designed to fit the Japanese physique, and while it has a solid construction, it provides an exquisite fit that makes it feel less heavy when worn. I purchased this as a used item in good condition and have used it about 7 times. The following is from the manufacturer's description ↓ This backpack is designed for skiing and snowboarding. With the RT gear rack layout, avalanche gear such as shovels and probes can be stored in a dedicated compartment in case of an emergency, allowing for quick access without hesitation. The SSHC system holds skis and snowboards and compresses the entire bag in one action. Access to the main compartment is located on the back, allowing for quick access even in bad weather. The large goggle pocket is sized to comfortably fit two goggles. The 3DS shoulder straps and 3DET frame, designed to fit the Japanese physique, reduce the weight of the luggage and interference with movement during gliding, and the CS waist harness provides a fit that wraps around the pelvis to prevent the luggage from swaying. ・3DET (3-dimensional, Ergonomics, Torsion) frame ・3DS (3-dimensional, Short) shoulder strap ・Stabilizer strap ・CS (Comfortable, Short) waist harness ・Waist harness pocket ・RT (Roll Top) gear rack ・SSHC (Ski, Snowboard, Hold, Compression) system ・Ice axe holder ・Hydration hole ・Goggle pocket ・Mesh pocket ・Back length 50cm ■Size: 35L ■Material: 100% nylon ■Weight: 1,700g No returns or exchanges to prevent swapping.
