The Drawstring Neck Dam,
Part # 510-533, is
the standard neck dam configuration on all SuperLite-17A/B & U.S. Navy MK-21
Mod. O & Mod. I Helmets. The post-1996 Model has an angled neck chute,
allowing the helmet to rest in a more comfortable position and lessening
front end ride up. It also fits a wider variety of neck sizes due to its
"trim to fit" design. There are no part number changes due to this
alteration.
As of 8/15/95, this changed part is shipped as
"standard" on all SuperLite-17A/B helmets.
