Top Stitch Tactical, a fully custom nylon sewing shop, is offering a molle pouch that may just actually deserve to be on a combat rig for more than just decoration. (I jest, but all too often I see MOLLE panels covered for the sake of being covered).
Coming in at the tip of practicality is the Essentials Allen Key Pouch. In short, its a MOLLE / PALS compatible pouch that through the minimal use of velcro can keep all the essential Allen keys one needs to maintain a weapon in the field. The pouch features complete internal retention (an extra inside flap) to keep the smallest of those pesky hex-sided suckers from disappearing during tactical activities.
Having tested a bevvy of multi-tools (see my review of the Real Avid here), there are still things that many of the tools do not cover, especially with the proliferation of small optics. The multi-tools come with some common sizes of hex keys, but they do not meet the full needs of one in the field.
For those interested, Triple Stitch Tactical will make just about anything nylon and tactical that one can dream over. For this interested in seeing past work or contacting them, check out their Facebook page or their website.
