This waist pouch can be used as a secret pouch to protect your valuables, such as your passport, cash, and credit cards, from pickpockets and snatch-and-grabs when traveling abroad. (For security reasons, it's best to avoid taking out and putting in your valuables in front of others, as this could reveal their location.) The pouch part is sewn shut at four points on the top, but items can be inserted from all directions. When running, you can put your smartphone, music player, etc. in it. It's a belly band type that fits snugly against the body and doesn't bounce when you run, which is a great feature. 【Color and Size】 Color: Black Size: L Width (flat): Approximately 32.5cm, Height: Approximately 13cm It stretches and fits. Thank you.
