LS2 Stream Motorcycle Helmet

My head measured 24 1/8 inches, or 61.3 cm. Which according to Rocky Mountain ATV and LS2 Helmets, put me directly in the middle of extra large. I am happy to say that I agree with this sizing. The helmet fit snug, but not overly tight in any way. I agree that it is a moderate to long oval shape. It fit well front to back and side to side. I could not get it to lift or rotate significantly in any direction. The cheek pads are slightly big, but are so soft that it's a very mild inconvenience.

I wore the helmet in the house for about 20 minutes with no discomfort. I also removed the interior and visor, then put it all back in. It took a few minutes of very patient work to figure each piece of it out, but it seems simple enough now. Also, I wear prescription glasses, and they fit inside the helmet and sun shield quite nicely. I felt no unusual pressure or clearance issues.

The next morning I took a ride. I left an hour after dawn and rode directly East in order to test the sun shield in direct sunlight. It works good enough that I no longer had to squint in order to see, but the sun shield isn't as big as the main visor. There is a gap of full brightness under the sun shield I found annoying. This is my first helmet with a sun shield built in, so I don't know if this is common or not. I rode 300 miles over a nine hour period, in which the temperature eventually reached about 89 Fahrenheit, or 32 Celsius. The helmet seemed decent in the hot weather. No better or worse than other helmets I've worn. I didn't feel any difference between having the vents opened or closed, but I've never felt a difference with other helmets either.

For what this helmet costs, I think it is an exceptional helmet, am pleased with my purchase and would not hesitate to recommend it.
