This offers an unprecedented level of comfort during hunting, thanks to the new carrying strap and objective lens and eyepiece covers. This creates an almost magical interaction between optics, ergonomics, and functionality, rolled into a masterly crafted design.p> California Proposition 65 WARNING:This product can expose you to chemicals including lead, that are known to the State of California to cause cancer, and birth defects or other reproductive harm.
