very odd fit, strap is very uncomfortable and cheap feeling, not worth the 36 bucks. I exchanged it with an HJC half face helmet and am SUPER happy with that one. costs about 18 bucks more but its better in every way.
Just wanted a half helmet for cruising around town on the backroads. It gets hot here in Georgia in summer. Can I complain about the helmets wind noise, NOT! A very good choice for me as I use it. The graphics are nice also. It's also very comfortable to wear. Buying another for the girlfriend.
Most half-helmets are either "novelty" or "for show" types that aren't DOT approved. They may look nice, but offer very minimal (if any) protection. This Skid-Lid combines both Safety and Sex Appeal. Has a well cushioned inside (just a little over .75 inches on the sides that pushes out to about 1.25 inches in the back and 1 inch in the front). It's not overly padded so you don't get that big salad-bowl-on-top-of-your-head look. Graphics are screened on under a nice and shiny clear coat so you don't have to worry about them peeling off or rubbing off like some of the other inexpensive helmets. the skull graphics look even better in real life!! For the money you pay (less than $50)you CANNOT go wrong). Awesome helmet AND the shipping from Jake Wilson was incredibly fast! You'll have it within 2-3 days evern with the standard UPS Ground shipping! Comes in the same box you would get if you purchased it in a retail store. I know because I bought one from our local Harley dealership before. You should go out and buy a clip strap conversion thing because you will have to cut the long strap. I cut mine other one too much and didn't torch the ends so it got all ratty. That's why I am buying another one... Skid Lid's are awesome helmets. Light, Secure, Safe, and Sexy.
