The GEARPOUCHX is our original gear pouch with an added velcro tab extender. This allows the pouch to hold devices larger then the original 4.5" up to 7" tall. It can hold an Iphone 6s or a Samsung Galaxy. Along with all of the great things you can put in the original gear pouch the X can hold longer EDC "every day carry" devices such as a flashlight. It measures 2.5" wide x 7" tall x .5" deep. This GEARPOUCHX has a unique vertical belt mount making it one of very few pouches that work with a bandolier keeping your pouch vertical which is key to the TAGH1 device.
