| PRIMALOFT® GOLD INSULATION ECO | PrimaLoft® is a patented microfiber that retains body heat, thereby saving energy. These ultrafine microfibres are designed to resist water, so the insulation stays dry longer and maintains its insulating properties. This synthetic insulation offers excellent breathability, ideal for demanding activities. Gold Insulation Eco’s performance matches the exceptional synthetic insulating power of PrimaLoft® while using 55% recycled polyester fibres. |
| VIBRAM® | Outsole providing excellent traction on mixed surfaces thanks to vulcanised rubber technology, ensuring high abrasion resistance. |
| IMPACT BRAKE SYSTEM | Innovative system applied to the sole to absorb negative impact on the ground, boost traction uphill, and improve grip downhill. The unique positioning of the lugs allows most of them to maintain contact with the ground for optimal impact absorption. |
