I forgot about the vents in the back...I popped those grommets out too. I did it to reduce the chance of a line getting snagged during an unstable deployment. On mine, the front vents stuck out far enough to catch a micro line. I removed the goggle strap because I knew I wouldn't use it and its one less thing to get snagged on the plane. Lots of frap hats have similar straps though. The best thing to do would be to have your instructor or S&TA take a look at it.

The only place the helmet has been too warm for me was in the plane on a hot day waiting for take-off. I usually slip it on as the pilot is powering up the engines for take-off then take it off at 1000-1500'. It's never been too warm in freefall or under canopy. Once I'm on the ground, I just hang it on my chest strap for the walk to the packing area.

I've been jumping the exact same Boeri helmet for about a year. I stripped off the plastic vents on the forehead and removed the goggle strap from the back so everything is nice and smooth. I just got a Dytter, but haven't mounted it yet. I plan on hollowing out a little of the padding to make a spot for it.
