That was kewl. The I-70 has more options (sun shield) but weighs less. The I-70 looks sleeker on your head. I purchased the I-10 about the same time as you. It was used for a couple weeks and now I've shelved it. I have a 15 helmet collection. I now use the Daytona 3/4 helmet as my main helmet and the Sistema II as my secondary helmet. The Sistema II is about the same in comfort/quietness as the RPHA helmet, the RPHA winning with a slightly better interior feel.Thanks for the review.
Just start using the i70 and see that it's quite snug fit inside... for how long that the interior pads gonna shape better fit with my head (cheek) ???
Typically I'd say it takes a few rides to get used to a helmet and break it in. Helmets definitely should be snug, but if it's leaving a deep creases on your forehead, it could be a size to small. Maybe I'll make a helmet fitting video!
