Sea to Summit

Australian-designed gear, tested from the backyard to the world's highest peaks

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

Is PAST Outdoors an authorised Sea to Summit stockist?

Yes, we're a genuine, authorised Sea to Summit stockist. Every product in our range is authentic and sourced directly through official channels.

Do I need a sleeping mat as well as a sleeping bag?

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.

What R-value sleeping mat do I need?

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.

Does Sea to Summit only make sleeping bags and mats?

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.

Which Sea to Summit sleeping bag should I choose?

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.

Awesome addition to my bottle to protect and keep cooler!

Guided South Island Serenity (NZ)

Having been to New Zealand a couple of times, and namely the South ISland, I knew when I booked this trip I was in for something special. For me the journey and the gear prep to get to the trailhead is one of the most exciting bits. Thankfully I'd picked up some LOWA boots, Fjallraven trousers, and an Exped mat in the lead up to this trip. Knowing that the trip was guided by the very team that kitted me out wiuth my gear gave me confidence I'd be comfortable for a few days on the trails. The pokey trails rambling amongst tree roots, occasionaly crossing creeks and rivers then opening up into stunning grassy basins sitting below snow capped mountains, what more could you ask for. We got it all on this trip (except snowfall). Dave and Seth knew the countryside well and ensured an enjoyable hike for us all. Would I do it again? Of course, in a heartbeat.

Past Outdoors Snake Bite Kit

The kit is well setup for its purpose,nice and compact in its case. Hopefully I will never need to use it but comforting knowing it’s there if I need it.
