The origins of Sea to Summit began in 1983 in Perth, Western Australia - a time when lightweight, outdoor products were hard to find in Australia. The original products were developed to outfit an audacious attempt to climb Mt Everest by beginning the ascent at sea level. This gear would need to work at every altitude over several months and be light and durable enough for the 5 month trek. The expedition was a success and so was the gear and the Sea to Summit brand was born.
