1. DESIGN: This is a flat and lightweight single pocket fanny pack in a sleek minimalist banana shape. Blank decoration, like the retro style of the 80s and 90s, a thin waist bag specially designed for fitness sports. Designers dare to create stylish and active small fanny packs that are as slim and light as mini fanny packs. Whether it's jogging training or night running workouts, it's more practical and comfortable than a mountaineering bag or a stylish fanny pack. 2. CONSTRUCTION: This grey single-pocket fanny pack still has a lot of capacity, with multiple compartments and a separate pocket for a phone holder. It can reasonably hold passports, keys, cards, iphone x and even larger phones without fraying each other. The waterproof nylon fabric blocks sweat and rain, keeping the interior dry and odor-resistant. NOTE: It is "splash proof" (not fully waterproof) and cannot be submerged in water. 3. Audience: Black adjustable belt for kids, teens, men or women. It would be a fun Christmas or Halloween fanny pack for boys and girls; a cool hidden sports fanny pack for teens; a teacher fanny pack; a dog walker for dad. 4. Scenario: Sojourners and hikers alike aspire to have a travel wallet anti-theft messenger bag for outdoor camping, biking, hiking, one-shoulder travel, carnival music festivals or carnivals. Or convertible into a travel fanny pack hidden under clothing. The thin and flat design makes it easy to conceal and carry. This will be the best one-shoulder fanny pack ride for summer. It's safe and allows your hands to focus on riding your mountain bike or motorcycle. 5. Usage scenarios: Runners want a waist pack like a harness belt, not only for exercising in the gym, but also for hunting, fishing, and dog walking. It is both a waist pack for dog training and a hip pack for mountain bikes. With extended shoulder straps, it can be used as a cross-chest backpack, or as a shoulder-to-shoulder bag. It is a functional denier fanny pack for everyday work and travel.
