Giro Switchblade MIPS Adult Mountain Bike Helmet - Lightweight & Ventilated Cycling Protection for Trail Riding & Downhill Biking

This is the bazillionth helmet I've owned in my 56 years on earth. I've worn $1850 motorcycle helmets and I've worn at least 50 Bike helmets costing over $150 each and many in the $300 range.Some are truly excellent helmets but I am a believer in the right helmet for the right conditions and in that pursuit, I needed a proper mountain cycling and trails riding helmet. I ride an eBike and I really wanted too have a proper excellent helmet that I could wear comfortably for hours and hours of North Carolina Summers and a little bit chilly Winters.After trying many full face helmets of many different manufacturers, I tried the Giro Switchblade MIPS edition. This one is an exceptional rendering of a modular full face with detachable chin guard. I am very impressed with Giro products and I am pleased with them, especially after really putting them to the test.Clearly I do not want to crash in order to test the crash worthiness of this helmet. However; Giro publishes their crash testing findings and this helmet has been awarded all of the certs that matter to me.This helmet is super comfortable so I can stand to wear it in the heat and cold and rain and such, for the 99% of the time I am not having an epic eBike crash. I have to say, this is very comfortable. Not just on the first minute of the ride, but the 6th hour as well.I've read some reviews which speak to a concern that the detachable chin guard wouldn't withstand the potential impacts it is designed for. Honestly, I am not sure why this would be a concern because It is super super sturdy and yank as you might, it isn't coming off unless it wasn't latched properly, which is user error.I have lots of non full face helmets, so I don't need another one but the fact that this can be released to become a really excellent open face helmet. I feel like I got two for one here and the fact that it is so easy to custom fit the interior and the extra cheek pads are helpful.The fit and finish is really excellent as well. So why did I rate comfort at three stars when I am really happy with this helmet? Because it lacks the interior padding I think it warrants. It is a bit thin on the top due to pads that are a little bit too thin on the top and upper sides. The helmet isn't UNcomfortable, it just lacks the interior padding that would put it to five stars in my book.I believe the price to be very fair given what you get. This is an impressive helmet!!!
