The Yeti Pro Aviar is a straight flying putter that works well for putting as well as throwing. We've developed the Yeti in a firm, grippy blend of Pro blend of plastic. It's somewhere between DX and R-Pro in both grip and firmness. The unique slightly concave top allows for a lower profile and a straighter flight than our other big bead models (KC Pro, JK Pro & Aviar Driver). The grippy firm plastic feels great in your hand in any weather.
