Maxpedition-Good, not perfect.
I have recently become mildly obsessed with this brand of gear (according to my girfriend anyway) and have spent a lot of time and money researching, ordering, and putting these things together. The bag is just the beginning! Then come the pouches and accessories.
I have almost $200 in my small EDC bag and thats just it, its small! I use the Lunada as my EDC bag and it just fits the bill. Dont get me wrong, the quality is second to none but the bags tend to run small. Hence the need for all the external pouches. I have also noticed that their gearslinger series tends to "ride" a little funny. They shift around a lot. There is a velcro tab that you can attach to your belt, but that makes it immpossible to access anything in a hurry. This is the primary reason I dont use it for carry. I use it more to cover a larger pistol on my person. It is however, a good place for flashlight, multi tool, ammo, first aid, etc.
I suggest going to youtube before you make any purchases. There are a ton of online reviews of individual equipment and it gives you a better idea of size.
