A goggle strap retention device (10) that may be attached as an after-market accessory to a motorcycle or other helmet (12) or, alternatively, incorporated into a helmet at the time of manufacture. The accessory embodiment comprises a unitary shell (16) having a spherical concavity adapted for fitting directly onto a helmet. In either embodiment, the contour of the retention device includes a channel (18) running the entire exterior circumference in which the goggle strap is placed during use. The retention device provides aesthetic and aerodynamic enhancements by elongating the rear portion of the helmet, and by channeling air from air inlet ports (24, 26) through air passageways to outlet ports (28, 30) to the rear of the helmet. |
