Safety First
By Walter Braithwaite Jr.

____ The topic is "Ballistic Shorts". The following might be a little graphic for the average reader but I can assure you it will make you think twice about running this year without them. First of all they are not to protect your laundry! Ballistic Shorts are the newest required piece of equipment required now by the IHBA and other associations throughout the country. If you run faster than a 10.99 ET you must wear them! Why Ballistic Shorts? Imagine coming out of your boat at a very high speed. The chute Jacket works and throws you feet first in the water at over 100MPH! Water pressure hits you body and goes into openings, yes your openings! The internal injuries it causes are very dangerous and could be fatal. Get the picture! The DVBRC may make them mandatory (rules committee will decide) for next season but you shouldn't wait another race to protect yourself. These shorts have been around since 1976 and were created by Lifeline products. It took a very bad accident this year with a racer out in California to wake everybody up and make these shorts mandatory! The shorts are several layers thick with the outer layer being made out of 1000 Denier Cordvra Nylon, The same as the race jackets. The inside layers are of ballistic Nylon that will stop all water from coming through. The inside is a Polyester Cotton liner. They fit right over your driving suit. Lifeline has them in stock in black and can ship them out long before the Sunbury race! You can call them at 928-669-9241.
