2 ounces of horsehair filling/ or foam makes a massive difference in gloves (8 for 147 and under), so why wouldn't a thick ass beard provide any cushioning against shots? I'm not saying it's the difference between getting KO'd or not, but there is a barrier of protection.
Why the **** would a beard or goatee make the impact of a hard punch less effective? Is a beard or a goatee going to protect your fall too if you faceplant? Dont be ridiculous.
Its allowed in boxing. Why dont you ask Manny Pac if his Goatee helped him from getting knocked into the Shadow realm against Marquez in the 4th fight. Maybe hed provide you some valuable information.
Some fighters have been known to weave Kevlar fibers into their beards , reinforcing their chin section.
