When you need a pouch with a good fit that also allows cables to exit, this universal model from Baribal may very well fit your needs.

The pouch is adjustable in all directions for small to medium-sized devices (GPS, radio, phone...) and has a secure buckle closure. The maximum diameter of a cylindrical thing you can carry is 60 mm / 2.4". For items this thick, the maximum height is 120 mm / 4.7".

Made of 25 mm and 50 mm / 1" and 2" webbing with ITW Nexus buckles. Mil-Spec NIR properties. The color is a bit greener than Ranger Green but less saturated than Olive Drab. See the comparison picture.

The PALS strap in the back can be weaved to form a 50 mm loop for use on a belt without an adapter. For better stability, you can use the VFS MOLLE/PALS Belt Adapter, Single Column.
