It holds all my gear and looks fantastic!!
Color: Rustic Montana, Size: 11.5" x 8" x 2", Color: Rustic Montana, Size: 11.5" x 8" x 2"
I wanted something to hold EVERYTHING. In the pic - 2 wallets, tactical flashlight, 2 personal bluetooth speakers, 2 pairs of Beats, chap stick, pocketknife. Missing are my reading glasses but they typically will fit in there too even in their protective sleeve. This would make a great gift and the leather is excellent feel and look. This is the Extra Large size and i am happy i went with the bigger one as i almost didnt. Wife thought it was a great purchased but mad that she didnt get the chance to gift it to me for Father's Day or birthday!! LOL
