O'Neill Firewall Inspired by O'Neill's 60-year history in wetsuit design; our body mapping research has shown us parts of insulation to areas that require more heat. Used throughout the entire snow outerwear range and adventure series in conjunction with 3M™ Thinsulate™ or down; Firewall reduces weight, maintains warmth and offers greater comfort on cold days.
O'Neill Hyperdry Keep rain and snow at bay with Hyperdry - Nano-phobic water repellant treatment is applied to the fabric so the garment repels spills and water and is also quick dry. It has the added benefit of maintaining the fabric’s natural breathability and adds softness to the garment’s feel. Used throughout the adventure series and snow outerwear line.
