Galvin Green Nash Pant - Tech facts: The VENTIL8â„¢ PLUS range makes use of carefully selected materials with unique properties. A VENTIL8â„¢ PLUS shirt transports moisture and excess heat away twice as quickly as a conventional polyester golf shirt. This is made possible by an advanced technology whereby the textile fibres are designed to disperse perspiration and moisture over a larger area, allowing moisture to evaporate considerably more rapidly.
