【Waterproof Pocket, One of a Kind】 Only STREAM waist bags feature a waterproof pocket. The inner waterproof pocket is made of PEVA material. This safe material meets US FDA standards and has been certified by an SGS certification body, effectively blocking out water, odors, and dirt.
[Wetness, odor, and dirt are irrelevant to this bag] Condensed plastic bottles, used sanitary bags, and rain-soaked umbrella covers go into the waterproof pocket. The main pocket, where your wallet and smartphone are kept, features a water-separating structure that prevents any moisture from seeping in.
[Selected as one of the Begin Best 100 in the December 2025 issue of Begin magazine] Featured as a "large-capacity body bag that can hold three PET bottles." It was praised for its attention to detail, including lightweight nylon material, 6-pocket design, and lightweight buckle that can be released with one hand, making it an excellent everyday tool.
[Large capacity yet lightweight at 285g (M size)] With a 6-pocket design, it can store a water bottle, smartphone, wallet, snacks, keys, and even a waste bag. The lightweight design (M size 285g / L size 315g) ensures comfort even after wearing it all day. The belt is adjustable from 84 to 153cm.
[Because it's something you use every day, we haven't compromised on the details] Features a smooth zipper with D-ring and loop, a durable lining, and a lightweight buckle that can be released with one hand. Designed to follow the contours of your body, it provides a stable fit that won't shift even when running or bending over.
