Quality product - Peltor Aviation Parts & Ac: Camelback Gel Sealing Rings HY80

I purchased these gel cups for my Peltor Range Guards and I found no issue with install, fit or durability. They are a definite upgrade for wearing eye protection or glasses. They conform against your head instead of sealing with pressure compared to the stock foam cups. With them now in use, I don't find myself doubling up on hearing protection in indoor ranges even with rifle calibers.
