The Mamut Grips 3 are the third generation of controller grips from Mamut and they keep improving the product. The Grips 3 were developed with the Quest 2 in mind and therefore offer the perfect fit for the controllers. However, these are the first controller grips that come with a Reverb G2 option if you purchase additional velcro straps. On top of that, these grips offer perfect compatibility with the Apto 2.0 Universal Gun Stock, so if you happen to own that gun stock, the Grips 3 are a must have!
