Finally, Ventilated Neoprene that Breathes! SMx VenTECH Girths are the new standard for equine comfort and technology with all the premium features you expect from a Professional's Choice product. The trademarked VenTECH technology features a ventilated, non-slip neoprene liner that conforms to your horse, allows heat and moisture to escape and keeps your horse cool, comfortable and performing at its best. Detachable neoprene liner peels away from webbing for easy washing. Professional's Choice recommends replacing your girth at least every 2-3 years, depending on use. It is recommended to regularly check your girth for signs of wear and tear, and replace immediately if any issues are detected.
