This is a waist bag specifically for SUP (Stand Up Paddleboarding) from Magreb. It can hold a 500ml plastic bottle. It has four holes for water drainage, allowing seawater to escape even if you get rolled by a wave. It was very useful for staying hydrated on the water. Also, there is a buckle that acts as a stopper to prevent the zipper from opening even if you get rolled by a wave, so you don't have to worry about losing your plastic bottle. - Brand: IMCREB - Color: White - Design: With zipper, with button - Strap: Adjustable strap Thank you for viewing.
