NANGA x JAGUY sierra cup with camouflage design, featuring a double zipper. - Brand: NANGA x JAGUY - Accessories: Carabiner - Zipper: Double zipper I've been using this to store a sierra cup for camping for about a year, so I think there's a sense of use. Sierra cups are a must-have item for both camping and trekking. This protects your sierra cup from dirt and scratches. Also, with the carabiner, you can hook it onto your backpack or hang it on a pole hanger, preventing loss. With NANGA's "iicamo" original print and JAGUY's sierra cup case docked together in a POP color, it creates a stylish camping site.
