A brand born from a genuine adventure
Sea to Summit
Sea to Summit's story starts in Perth, Western Australia, where a teenage Roland Tyson began designing his own outdoor gear on a secondhand sewing machine. The name itself comes from a genuine feat of adventure — a solo climb from sea level to the summit of Everest — and that same spirit of pushing further with better gear has driven the brand ever since.
Today, Sea to Summit is distributed in over 70 countries and has picked up more design awards across more categories than almost any other brand in the outdoor industry. But the philosophy hasn't changed: obsessive, real-world-tested design that solves genuine problems for the people using it.
What sets Sea to Summit apart
Genuine design innovation
From patented Air Sprung Cell mat technology to the Free Flow Zip system in their sleeping bags, Sea to Summit consistently rethinks categories other brands take for granted.
Tested in the real world
Every product is developed through genuine field testing across some of the harshest conditions on earth, from the Australian outback to the Himalayas, not just in a lab.
Australian-founded, globally trusted
Still headquartered in Perth, Sea to Summit has grown from a one-person workshop into a globally distributed brand, without losing sight of where it started.

Frequently Asked Questions
Yes, we're a genuine, authorised Sea to Summit stockist. Every product in our range is authentic and sourced directly through official channels.
Yes, and it matters more than most people expect. A huge amount of overnight heat loss happens through direct contact with the ground, not the air around you, so pairing your sleeping bag with a proper sleeping mat is essential for staying warm, not just comfortable.
For most three-season Australian conditions, an R-value between 2 and 4 is sufficient. For alpine or winter trips, look for an R-value of 5 or higher.
No, Sea to Summit's range spans dry bags, camp kitchen gear, pillows, packs, and more. Sleeping bags and mats are just one part of a much broader, genuinely well-designed range.
It depends on your priorities. The Spark and Spark Pro suit hikers chasing the lightest possible weight, while the Ascent offers a roomier, more versatile fit. Our free comparison guide breaks down the full range if you're still deciding.
