PANTAC have come up with a Deltoid protector that basically does as what its name suggest. Instead of having to slip your arms through to take it off, there is a quick release velcro that you can rip open to take it all apart with ease.
A-TACS is a new and radical advancement in camo design and technology, developed by Digital Concealment Systems (DCS). Most traditional digital camo patterns use small square pixels, which is insufficient to visually reproduce the natural formations (e.g. shapes, forms, or shadow.....etc) appeared in environment.
The A-TACS pattern by comparison removes the sharp angles and replaces with very small organically shaped pixels, and adds specific colors carefully chosen to match the natual environment, and taking this process a step further the small organically shaped pixels are placed within larger groupings to create a "pattern within a pattern" effect. This radical advancement means that A-TACS is able to conceal the operator far more effectively and at greater distances comparing traditional camo patterns. Pantac has taken the step even further by adding the A-TACS pattern to their combat gear sections. This time as a MOLLE flat-square utility pouch which is extremely rugged. The Deltoid Protector is perfect for people that feel a little bare when they go into skirmishes with a shirt and a vest and may feel a little vulnerable. It'll fit over your arm, and protect your shouders from any impact. There is a Velvro attachment on the inside which you could fasten to your vest Molle.
