Inspired by O’Neill’s 60-year history in wetsuit design; our bodymapping research has shown us parts of the body that need more insulation and we have therefore adapted the type and level 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.
