MIPS: Founded in 1996 by a neurosurgeon and a researcher from the Royal Institute of Technology in Sweden, the Multi-directional Impact Protection System (MIPS) is designed to add protection against rotational motion transmitted to the brain from angled impacts to the head. Rotational motion is a combination of rotational energy and rotational forces from angular acceleration that both increase the risk for brain injuries. MIPS’ added protection has been independently proven to reduce rotational motion by redirecting energies and forces that would otherwise be transmitted to the brain. Data and info provided by MIPS.

Amazing fit

I am very pleased to say my helmet has an amazing fit and that is something that was very important to me since I ordered online. I did try to follow all important rules in terms of how to measure and shape, and did my research, but it is great that the fit is really perfect. Also the color is very very nice, even nicer than in the picture which is just and added bonus. I also really love Equine Exchange Tack Shop’s costumer service. It was amazing
