I have both the MIPS and standard, non-MIPS versions of the Agilis. I purchased the MIPS version for the additional crash protection it is designed to offer.

The non-MIPS version is noticeably cooler. It moves more air under the Styrofoam. It also fits my head shape perfectly, as did the several Atmos helmets I used prior to buying the standard version of the Agilis.

The Agilis MIPS version does not move as much air and is just plain 'hotter'. The addition of the MIPS rotational inner shell also made the fit...not fit. It just doesn't feel comfortable on my skull. The MIPS liner is also a 'hair puller'. While wearing it and when removing it it likes to grab hair and try to pull it out. The MIPS version is also heavier. That's kind of a non-issue, but the difference is easily felt just holding the MIPS version in one hand and the standard version in the other hand.

I have to adjust the Roc-Loc so tight on the MIPS version in order to keep it from rattling against my sunglasses that it can give me a headache. No such problem with the standard version of the Agilis.

The MIPS version is a step backwards in every area except for the increased safety. I do not recommend buying it. I'm back to using the standard version and will possibly replace it with an Aether, but only after trying one on locally.
