I bought an XL helmet . . Once on it wasn't too bad but getting it on and off, I couldn't wear my earmolds and had to take my ears off, so back it went! No dramas returning it. I also bought the large cover and am happy with it for $29.99. Also bought the compression pants/tights and compression jacket for $35 each and am happy with them.
I had previously bought the balaclava with a bib and it worked well the only time I've worn it . . Recently on bloody freezing ride on the way back from Yeppoon in June.
Also bought 2 of the the Aldi Bluetooth headsets . . Mounted my iPhone on Ram ball and connected to it. I then had GPS, phone, music and intercom . . . All worked well . . Could not use earmolds with them thogh . . Only supplied speakers and they ran out of usable volume around the 80 kph mark.
So bought a Sena 10 and the Hub to pair with it, so then had Garmin GPS, iPhone, iPod, UHF radio, intercom and earmold ability. John, Barry and I have also used the multi headset pairing and up to around a kilometre and line of sight, this is bloody fantastic, clear as bell, no button pushing, great . . Any further apart and it's back to the UHF for coms, further away we can use the phone.
I've just taken delivery of a Sena 20 S at $329 delivered to my door within 2 days . . So far impressed but still exploring it's capabilities.
