About Sea to Summit

Sea to Summit was created by Roland Tyson in 1991.

Roland started making outdoor gear on an old industrial sewing machine in his childhood bedroom in 1983, at the age of 17. As a young outdoor enthusiast, Roland realized that he had a passion and a talent for creating cutting-edge outdoor equipment. Soon he was designing and manufacturing equipment for other Australian adventurers. By 1991, after outfitting an unusual first ascent of Mt. Everest (a 1126+ kilometer, 8848 meters in elevation trek from sea level to a solo summit), Sea to Summit was born.

Roland’s drive to design the best, lightest, and most durable equipment would take him farther into the remote Australian outback and eventually into the Himalayas. In these wild places, he could put his inventions to the ultimate test.

In 1993, Roland was joined by Penny Sanderson, who had spent six years at Australian Geographic. Her passion for exploration and innovation was a perfect fit for Sea to Summit. She and Roland began traveling several months out of each year, spending time climbing, sailing, trekking, overlanding, and biking. Everywhere they went, they tested products and iterated design.

Sea to Summit quickly grew into a successful global brand, with Penny and Roland’s love of travel and design as the foundation. Together, they own and manage Sea to Summit, still taking part in every step of the journey from developing raw materials to putting perfected gear into the hands of customers worldwide.

Sea to Summit Review

I received the Big River Dry Backpack (50L) to review in this post. It’s a very practical bag that is durable and useful for outdoor adventures. I travel often and a dry backpack helps to protect my belongings on land and in water.

The specs of the bag include the following:

  • Dimensions: 23.9 x 13.6 x 11.2 in
  • Weight: 1lb 10 oz (760g)

The package arrived in a huge box and was neatly packaged.

Sea to Summit Pros

  • Waterproof – The bag is fully waterproof.
  • Minimalist Carry: Streamlined and adjustable EVA foam pack harness with supportive sternum strap and removable 1.5″ / 38mm webbing hip belt holds pack firmly in place
  • Excellent Construction – Built Tough: Heavy-duty 420D Nylon fabric is super-strong, abrasion and puncture-resistant with a triple-coated oval base for increased water-shedding and durability
  • Grab + Lash: Strong and versatile grab-handle and daisy-chain for confident handling and lashing to kayaks, bikes, motorbikes, and roof racks
  • Minimalist Design – The design is very basic. There are no additional pockets or features that would weight the pack down.
  • Very Lightweight – The bag weighs 1lb and 10 oz (760 g)
  • Compatible with other Sea to Summit compression bags.
  • Comes in two colors; Black and Red
  • Comes in two sizes: 50 L and 75 L
  • Lifetime Guarantee
  • Free US Shipping on orders of $50+

Sea to Summit Cons

  • No Smaller Options – I would prefer a 25 or 30L option for smaller trips.
  • No Additional Pockets – The Big River Dry Backpack has no other internal pockets. It’s pretty basic yet useful.
