I like the neoprene lining. About the heating - is this like a mouthguard where you would boil it to mold into shape? I like that idea. Would love to see how it works. I'm not always happy with how Baskervilles sit and wish they were a little moldable.
This type of muzzle doesn't fit for a breed like a french bulldog, but that's kind of a niche market. The best build I've found is a mesh fencing mask style, but it still doesn't work for some.
They make brachy muzzles out of mesh. They look kind of silly, though. https://www.amazon.com/dp/B00J59JBPM/ref=cm_sw_r_cp_apa_ji09BbG5GN5GB
