Vibram's first mid-range, the Ibex, is a stable, controllable approach disc. The Ibex can handle a good amount of power and does not mind powering down and holds a hyzer straight much longer than one would expect. If you've got good arm speed, you are going to love popping the Ibex high up in the air on a slight anny and watching it take a smooth, seemingly unending fade.

X-Link
The X-Link material is a unique rubber-based compound which resists scuffs, has incredible durability and unequaled grip. Additionally, X-Link has a stronger memory than any disc currently on the market, so if you do manage to bend it out of shape, in all likelihood, it will work its way back.

X-Link Firm
X-Link Firm is a rubber-based compound which is based on Vibram’s X-Link. It is a special blend designed to maximize the firmness of the disc while maintaining as much of the grip and durability that is found in the base X-Link material. Over 50 formulations were tested in the creation of X-Link Firm to create its optimal performance.
