HJC IS 16sn
This is a good overall helmet for the price, the retractable shield works well, cheek pads are well supported I would recommend this helmet if its in your price range.

For the price this is not a bad helmet. I have worn it in temps down around zero and stayed warm. Sweat in temps around 25-30 though. Even with the vents open. The inner visor I like a lot. Works out very nicely on sunny days. The fit seems for me at least to be pretty good. No slopping back and forth but room enough where my head doesn't feel squeezed.

Great Helmet, Great price
I picked up the HJ IS-16 from dennis kirk. I am very satisfied with the helmet. It is lightweight and comfortable. The slide down lens is a nice feature but does seem to fog up easily. The lens comes down far enough as to not obstruct vision. The helmet did have a minor paint defect and the dual lens does not seem to seal against the helmet very well. Other then that I wouldn't hesitate on picking one up, especially at its price point.

Good product, some problems
The helmet is great, except the sun visor shield fogs up really quickly and is hard to unfog

HJC Flat Black IS-MaxSN Helmet
Like the looks and fit. Had the front shield in front of the nose guard fall off easily, left it off, does not seem to do much anyway. Also had the clip for the sun shield pop off, snapped it back on, seems to be OK. Love the integrated sun shield! No more throwing on sunglasses and having them hurt. Overall I'm happy with this helmet.

Good, but Not to my Expectations
I own 2 other HJC Helmets and they were great! but HJC helmets has changed a lot as far as fitting and new visor attachment. It fits really snug. I know helmets are suppose to fit on the tighter side but I have trouble putting it on. I normally get a Large but I got an X Large.

The good- defrost shield

Now the bad... I was riding today and went to prop up the visor and it came completely off!!! not happy
- The RapidFire™ Shield Replacement System is fast but the visor can come off while riding
- the sun visor fogs up bad when you come to a stop but defogs again when moving
