The HJC IS-33 Open-Face Helmet
First off, the HJC IS-33 is a very nice DOT-approved helmet at a good price. The polycarbonate composite shell has clean contours and easily accessible vents that breathe well when open. Paint quality is excellent The SilverCool anti-bacterial/anti-odor interior is plush, comfortable and easily removable for washing.
Our test helmet has a 60cm circumference, which is called a Large on HJC's size chart, but said head is a bit longer than its is wide, leading to the XL being a better fit. Available size range is XS to XXL.
Sure, photochromatic faceshields are nice, but the built-in flip-down sun visor on the HJC IS-33 works great. There are three locked-down positions, and top-of-shell push-button retraction is pretty convenient. The main faceshield has good optics, and the 'QuickSlide Shield Replacement System' makes it mega-easy to remove and replace.
Particularly in liht of its low cost, this is an excellent lightweight, all-day-comfortable helmet for those times when you want a bit more fresh air but aren't quite ready to eat bugs.
