Soft, durable and slightly elastic fabric pouch with integrated strap, buckle and Velcro. An iPhone or similarly sized and shaped device slides in through the slot to be carried inside; the transparent window on the front allows the device to be viewed at a glance.
Not really for Airsoft as it has no rigid protection to guard against BBs, hits, brushes or hard knocks. Instead, this sort of thing is for runners or hikers that need to carry such a device away from pockets.
The pouch does have small holes to thread wiring through so you can leave headphones connected while carrying. This model is available in various different colors and camo schemes.
