The Shred Ready Super Shaggy Helmet features the H.O.G. retention system which fits behind the nape of your neck for a secure, custom fit. The Shred Ready Shaggy is a classic billed helmet with smooth, round lines. The Shaggy has added volume which increases the size to fit those with more hair and larger craniums. The four-point retention system means the helmet can be worn forwards or backwards, meaning that it can be worn with the bill in the front or back. The Shaggy includes interchangeable compression molded closed-cell foam fitting pads that attach via double sided hook and loop fasteners. The Shaggy also comes with Shred Ready's Helmet Replacement Program which states: If a helmet's function is compromised by normal use, Shred Ready will exchange it at their cost for a new replacement plus shipping.
