The Cutt'n 2.5 diaphragm call now uses new Infinity Latex™, which requires less air pressure to use and delivers more realistic sounds. It's a 2-1/2-reed call with a Premium Flex frame. This new frame design retains shape better and is more comfortable in the mouth, resulting in superior performance. Soon you'll be cacklin', cutt'n and yelpin' like the real thing.
