The Ultra 4 S brings in a new era of recurve stabilization.
It builds on the success of the Ultra 3 line which has dominated international competition at the highest level for years pushes the boundaries of what recurve stabilization can accomplish.

The Ultra 4 S is 20% stiffer, features our thinnest diameter to date, removes more vibration, and is 7% lighter than the Ultra 3 weighing only 4.5 oz.
