The Atmosphere by YoYoJam is Makoto Numagami's signature yo-yo, first released in 2009. It is made out of celcon with metal weight rings, just like the New Breed. The only difference, is that the Atmosphere has brass weight rings instead of aluminum. The side caps are also recessed into the body of the yo-yo, to allow for thumb grids with no real need of removing them. It also features a large C-bearing and silicone O-ring response.
