I went from a Xar to one of the original IXS trails a few years ago. Didn’t get on with the fit at all (and I bought it from my LBS so I thought it fitted!). Ended up with a Scott Stego and then another one after I smashed the first one.
That was a great helmet. Not sure if they still make them and they weren’t cheap. Then went Giro Montaro but the MIPS came apart so sent that back. Ended up with the Oakley DRT5 which is my fav helmet ever. Again not cheap.
Having said all that, I also have a Giro Feature (non mips) bought cheap from LBS as a backup helmet and I really like it. Way better fit than the Montaro.
