Chest hair's often best left-as is. Unless you're a competitive body-builder and need to shave and trim for competition. But some men, especially as we age - are prone to ridiculously long chest hairs. The kind of hair that gets snagged in shirt collars - on when buttoning buttons. Some men like to groom thier chest hairs - well just slightly shorter - to preserve one of their best assets. For these, a full-size home hair clipper set with plenty of guides from #1 to #8 will give you the control and length you want.
