Sea to Summit Delta Insul-Mug

This mug features a groundbreaking advancement in thermal insulation. Sea to Summit® uses an integrated molded polyurethane sleeve that insulates the liquid inside the mug, unlike double-walled mugs which only protect your hands but don't keep your beverages hot or cold. Excess liquid flows back into the sipping hole because of the concave design of the lid.

Following a successful 1984 climb up the north face of Mount Everest, one of the summiteers, Tim Macartney-Snape decided to return six years later so that he could do what no one else had done - climb it starting from sea level, that is from "sea to summit".

For this trip, in 1990, Tim swam in India's Bay of Bengal and then set off on foot across the Gangetic plain toward the distant Himalayan foothills and four months later, set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.

Back in Australia, he joined forces with friend Roland Tyson to build a business that could make use of their knowledge of the outdoors to create truly ingenious, well-made but affordable outdoor equipment. They named their company Sea to Summit® after Tim's expedition and the business prospered. Today the Sea to Summit brand continues to provide innovative gear and serves a growing band of outdoor enthusiasts all over the world.
