The Yeti Aviar is a lower-profile Big Bead Aviar made from a special blend of pro plastic that is somewhere between DX and R-Pro in grip and firmness. The result of this unique blend and design is a very accurate point-and-shoot putter with a concave dome. The concave dome reduces the risk of glide-out on putts that catch a wind on their way to the chains. It's not too often that a major innovation occurs wiith putters, so we're super-excited for this new release.
