If you like the concept of the original HSGI Costa Leg Rig but you wish you could change the pouch configuration to suit your needs, I have good news. HSGI has just released a PALS compatible version of the Costa Leg Rig called the Costa Padded Leg Panel.
It has the same 2 point mounting system that sits just below the belt line as the original. It also retains the light padding of the original. The difference is that this model features a 3 row by 6 column PALS field so that you can attach which ever compatible pouches you want.
