Classic high-altitude sunglasses

Sunski’s Treeline is a medium-large sized frame ideal for high glare conditions, like winter mountaineering, snow sports and alpine climbing. With maximum wrap and great all-round coverage that can be further boosted by inserting the removable magnetic sun shields, they’ll keep your eyes safe and squint-free, even against blinding white snow. High contrast polarised lenses also boost your vision in challenging conditions, while grippy rubber nose pads keep the Treelines in place, ensuring they never slip or slide. Classic looks and a keyhole bridge evoke the golden age of exploration. And like all Sunski shades, they’re sustainably made from Superlight recycled polycarbonate resin.

Superlight frames are made from strong, light and comfortable recycled polycarbonate resin, created from scrap plastic that would otherwise end up in landfill. Sunski intercept this from the waste stream and reformulate it into their SuperLight resin
