I have purchased several belly bands and I enjoy using this model the best. It combines a 3-holster band (left, right and middle of back carry positions) along with several pockets for carrying extra pistol magazines, knives, mini mag-lites, etc. The band itself is a full 6 inches wide and is available in several lengths, to properly fit your midriff. It can be worn inside or outside your shirt, and can ride low (at waistband) or high on your chest.
It is made of breathable material which makes it comfortable for long-term wear. It also provides some support for those of us who are amply built. The firearm retention straps are made of elastic and leather and are secured using velcro. The band itself is secured around your middle using a velcro section measuring about 6x7.5 inches, to allow for proper adjustment and firm fastening.
As you can see from my photos, my Springfield XDS 4" 45ACP is practically invisible under a light-weight t-shirt, yet easily accessed if necessary. This is my every-day carry holster and I am very happy with it.
