Camera Essentials is exploring making rain poncho's for Stabilizers - we have made a small run of ponchos and are 'testing the water' :)
The Rain Poncho's are made of black waterproof-breathable fabric, and have two velcro 'access' flaps in the front for the stabilizer arm to emerge.
Otherwise, it's your basic Poncho, goes over the head and has a drawstring around the neck.
The Poncho is 36' from shoulder to front hem, and 42" shoulder to rear hem (longer in the back).
We didn't make it with a hood, just a drawstring at the neck. What would you prefer?
