Large Capacity:With capacities of 1.7L and 1.3L (dimensions: 24 x 10 x 8.2 cm and 22 x 9.5 x 8.2 cm), the bag offers ample space for a wallet, smartphone, tools, and more. Side mesh pockets are ideal for securely storing small items. Ideal for smartphones up to 6.8 inches, such as iPhones or Samsung Galaxy devices.

Highly Sensitive Touchscreen:The TPU film allows for easy touchscreen operation on the go. Velcro closures keep the smartphone secure, and the hidden headphone port allows for calls and music while driving.
