Designed from natural and recyclable materials using bio-based materials, the ASPENX | Vuarnet Trek features flexible, yet ultra-resistant frames (scratch and shock-proof) and lenses made from natural nylon and produced in France. Vuarnet’s mineral glass lenses, manufactured in its own factory near Paris, are 100 percent natural, 100 percent recyclable, un-scratchable, ultra-resistant, and timeless. The shield design extends the field of view more than 180 degrees, making the Trek the perfect sunglasses for active winter sports, like skinning and Nordic skiing. Integrated soft-touch rubber inserts inside the front and temple tips and adjustable rubber nose pads create extra grip and comfort.
