            The origins of Sea To Summit began in 1983 in Perth, Western Australia - a time when lightweight, outdoor products were hard to find there. Roland Tyson, a keen climber and adventurer, began making his own gear on an antique sewing machine in his bedroom to meet these needs. In 1990, Australian mountaineer, Tim Macartney-Snape, approached Roland to make gear for his upcoming expedition – an audacious attempt to climb Mt Everest by beginning his ascent at sea level. Decades later, this spirit still defines the them: a company driven by design perfectionism that allows them to develop ingenious, functionally beautiful products with a “no worries” Australian attitude.
