In Nepal, four former British special forces soldiers were outfitted with bioplastic sunglasses from Teysha Technologies as they set a mountaineering record for traveling from the UK to the summit of Everest and back again in under 7 days

The Mission: Everest team was comprised of Kevin Godlington, Veterans Minister Colonel Al Carns, Major Garth Miller, and Anthony “Staz” Stazicker. Godlington wore high-performance, biodegradable sunglasses made from Teysha Technologies’ proprietary plant-based polymers. The specialized eyewear can withstand temperatures as low as -40°C while maintaining optical clarity and protection against harsh mountain conditions.

The accelerated trek timeline was made possible by new acclimatization techniques that helped the team bypass the typical 4-6 week altitude adjustment period at Everest Base Camp. By limiting time spent at Base Camp, the team reduced the typical expedition’s carbon footprint by a third and cut food consumption and human waste to just 10% of a standard ascent.

“Our accelerated approach, combined with Teysha’s biodegradable technology, represents a new model for responsible mountaineering,” said Godlington said in a press statement. “We’ve proven this can be the most sustainable mountaineering mission yet.”
