SPIbelt® have engineered the SPIbelt® Dual Pocket PRO for comfort and maximizing carrying storage capacity. This belt has two pockets, the smaller pocket size, which expands to 6.5x3x2", and the larger pocket, which expands to 9x4x2". The Large Pocket easily accommodates large smartphones, including the iPhone® 13 Pro Max and Samsung Galaxy® S20+. The pockets are arranged closer together for a better fit, and we’ve also increased the width of the elastic band for stability and comfort.
