This lil guy is a solid admin design spawned as a frankenstein of the sheath pouch, barnacle, and clip-on phone holster.
When looking at the front, the sheath is on the left and is good at holding a flashlight, pistol mag, or a multitool. A grommet is at the bottom and the flap is velcro attached so can be adjusted to fit these type items up to 5" tall. In the middle is the Barnacle style pouch, which consists of a velcro closure external pocket and the main inside pocket has double zipper closure. The main pocket has folded accordion style sides and a middle divider with soft felt to play nice with your more fragile items. The external flap pocket doesn't hold much, but the inside is great for holding electronics like a small camera, PDA, or MP3 player. On the right is the phone pouch which has elastic sides and an adjustable strap to let it fit up to a 5" tall phone, not counting an antenna. If you do have a biggun antenna phone, the holder strap is small so it will not get in the way. All 3 of these goodies are sewn on a panel which has PALS loops on the back that use 2 short Malice clips. The panel itself is a velcro sealed slim pocket with elastic inside divided into 3 loops. The loop side of the panel closure is actually only sewn on one side so it can fold. I'm not so sure about this decision myself, but the design intent was one can put a longer item in the elastic loops and it could go underneath the velcro and the compartment would still close. This area is made easier to open with a webbing tab and plastic D-ring.
When it comes down to usability, the Triad does work well as a chest mounted admin pouch. It is big enough to hold many items, however still small enough to leave plenty of room to shoulder one's weapon. As for other options I think many people will find adding the Triad to backpacks and larger bags very useful as well. The main down sides would be the pouch divisions are pretty specific so if say for example, you don't have a phone or GPS, you can't do much with that part of the Triad. Overall, the Triad is a good use of combining some old ideas to make a new one. Currently available in Black, OD Green, Khaki, and ACU.
