This is my second Giro helmet, and a step-up from the first. Size is L for a head measurement of 23.25". Fits well, and internal MIPS harness is easily adjustable, with plenty of adjustment up or down. Have used the helmet in transitional fall temps, but not yet on very hot (testing the cooling vents) or very cold (with thicker skull caps) weather rides. There appears to be enough adjustment available for a good fit with both light and winter head coverings. My only complaint: I'd like the option of a minimal, removable visor for sunny days, which my lower-priced helmet had. Without the included visor, I've added a visored cycling cap to my kit. The helmet value came from purchasing this helmet on sale.
I've been using a dark grey POC Ventral for the last few years. It's been a great helmet, but got a little hot during the long summer endurance races I would ride. I've never owned a MET helmet before, but was inspired by Tadej's dominant performance this year and decided to imitate! (I know, I know - fanboy stuff). I got it in white this time to try and keep my head cool on hot summer rides. This helmet vents great and while quite a bit more compact than the POC (external dimensions), it feels great and so far, I love it. Catch it on sale and I think it's a great value!
I recently purchased the Giro Eclipse Spherical MIPS helmet to replace a Kask helmet. Though my Kask fit well, this helmet is much more confortable from both a fit perspective and airflow. I use it for both long road rides and commuting. This helmet is incredibly comfortable and lightweight. Initial adjustment was very easy and getting it dialed in was great. It is definitely the most comfortable helmet I have worn. I highly recommend this helmet!
The POC reviews are legit. It�s a great helmet, well made, and what you�d expect for the price point. I rode Rudy�s for a long time, including 2 crashes. Then I bought a bargain Lazer, which never fit well. I was always worried it would bounce loose on impact. The POC is comfortable, rides great, and looks like it will do its job if needed in a crash. Sizing is corrects and it hugs the head like it should. Your head, and safety, are worth what you pay for this helmet
