When traveling, you can't let go of your smartphone. Search for maps, use translation apps, take photos, etc. While smartphones have evolved and become more functional, they have become larger and heavier. For those who have a large smartphone or two devices, it is more burdensome to carry in your pocket or by hand. That's why we felt the need for a bag that specializes in "comfortably carrying (moving)" and planned and produced this "smart bag". Of course, smartphones are a necessity not only for travel, but also for commuting and holiday outings. I hope that many people who use this bag full of ingenuity will feel the ease of action. ・Material The glossy, shiny, and high-quality water-repellent fabric and water-proof zipper make it suitable for sudden rain and dirt. The back side is knitted, which looks beautiful and is soft to the touch. ・Internal structure Zippered two-tier pocket that is particular about "easy to organize" Small items should be placed on the lower tier (height 6cm), and longer items should be placed on the upper tier (height 10cm). You can store what you need according to your size. The loop inside can be attached with important items such as keys and IC card cases. Put your smartphone in the inner pocket External structure You can also store your smartphone in the back pocket. Your passport will also fit. It has a button to prevent it from falling out. Surface structure Cinderella fit with a passport in a quick zipper pocket! ! It has a water-proof zipper and a zipper tab that is easy to hook and close on your finger. ・Shoulder strap (minimum 83cm ~ maximum 150cm from metal fittings to metal fittings) The mainstream strap width of a typical small bag is 2~2.5cm. A The Mastery Trip series uses a wide shoulder (3.2cm wide). It reduces the burden on your shoulders and allows you to carry it comfortably for long periods of time. Non-slip even over suits and jackets It is a pair specification that can be used regardless of gender with two colors of metal fittings (black and gold). The loops on both sides of the bag are also a key point. By changing the way the shoulder belt is attached, you can change the bag to either vertical or horizontal use. *If you prefer a thin strap width, you can also use it by joining a A Mastery sash cord. By removing the shoulder strap, you can use a round carabiner and attach it to your own bag pack. The carabiner can also be removed depending on how you use it.
