I use these pouches for several different applications. While it does all of them well, it does none of them perfectly. It's satisfactory. Initially, and even now, I am very impressed with the overall quality and finish of the pouches. They look better in person. Before I bought them, I found that it was difficult to find information on how much room this rig actually has. It has a lot more room than it appears to. You can cram tons of stuff in it if you don't mind being a little uncomfortable. You can get a medium size pocket knife or even a full size pocket knife in the middle of the pouch if it has a clip. Most of the emphasis I found on the internet was on all the different ways you can wear it, but not its size. As far as the appearance and outside dimensions, it's small enough that it doesn't really get in the way, but overt enough to "scare the natives" - you probably wont care to wear it on your chest in public. If you wear it on your belt, it doesn't look too bad. Starting from the side closest to your body, the rig has a (water resistant possibly, but not water proof) pouch that is removable with what looks like a water resistant zipper. Virtually any cell phone could fit in this pouch with lots of breathing room for other items. If you remove this pouch, you can take up the slack in the outer part of the rig with the top button in order to wear the rig without the inner pouch. The next part of the pouch, the middle part, has a nice design. This is where this pouch has really earned its keep. I guess you could call this a tool compartment. When you unzip it, the front part hangs down at about 45 degrees from little straps that keep it from dropping all the way down. On the inside of the door (I don't know what else to call it) it has a small open pocket, and a few smaller, pen sized pockets. The side closer to your body has a small net at the bottom for small items, and a few wide elastic bands for storing items that cross the pouch horizontally in the middle. I have found this part of the pouch to be the most useful. You're not going to get anything huge in here, but you would have very easy, quick, and secure access if it does fit. One part that I found slightly misleading was the front part of the pouch. A mini mag lite just *barely* fits in the flashlight pouch. it's almost too long. the velcro on the cover is barely hanging on. I have a swiss champ that can fit in the smaller pocket, but you would be hard pressed to get anything much larger in it. One of the biggest caveats of this pouch is one of the biggest features. The straps easily disconnect, which is nice, but while there are better straps available, the straps that come with the pouch can become uncomfortable pretty quick if you're wearing it over a t-shirt. It takes time to get the straps just right. Too tight and you can't breathe - too loose and the rig sags and swings around. It's difficult to find a happy medium. If the straps are uneven, the straps bunch up on the back. Another problem with this rig is that if you wear it on your belt, I have found that the strap doesn't stay buttoned. The belt strap itself is large enough that it would be difficult to lose the pouch even if it was unbuttoned, but under certain circumstances, such as if you were upside down, I could see the pouch falling off your belt. Although I have a lot of negative things to say about it, overall, it's not too bad. If it's appropriate for your application and its small size isn't a hindrance for your equipment, then you're not going to find anything much better. I wish that I could give more constructive criticism of the pouch, but I'm honestly not sure how hazard 4 could make this a better pouch and it still be the same pouch.
