ARK: Pioneering Excellence in Swimrun

At the heart of ARK, our crew has been all-in on swimrun since day one.

Rooted in the Stockholm Archipelago, their heritage is intertwined with the islands where they were born. They proudly develop their products in the heart and birthplace of swimrun, drawing inspiration from the rugged beauty and challenging landscapes that define their home. Their connection to the archipelago shapes the essence of their brand, reflecting the spirit of adventure and resilience inherent in the swimrun culture.

They officially joined forces back in 2017, driven by a common goal: to build a brand that delivers the fastest suits and top-of-the-line gear and equipment for swimrun and endurance training/racing.

Starting ARK meant setting some clear goals and dreaming big. While other brands were not focusing in the segment, they decided to go all-in.

Ark is the first brand fully focused on swimrun, dedicated to innovation and crafting the best gear for athletes in the sport.

But Ark is  not just another brand; it's on a mission to do things differently, find new ways to connect with their community, and, of course, create gear that's not just good but truly groundbreaking. Ark is pretty confident to be onto something big – creating the fastest swimrun gear in the world!"

  • ARK HI-VIS BUOY

    €44.95

    Two products in one — you can use it as a dry bag or a Hi-vis safety buoy.

    ARK has downscaled the essence of what we need in a safety buoy and ended up with this clean design and lightweight safety buoy.

    Ripstop nylon fabric makes the Hi-vis buoy very lightweight and durable. Combined with the slim cord, you will swim without any restrictions.

    Just catch some air in the dry bag and fold the opening quickly to use it as a safety buoy on your swimming adventures. You can have your phone or keys in the buoy during the swim as the buoy is waterproof.

    When you are done swimming, you can use the Hi-vis buoy as a bag again and put your wetsuit and gear inside.  The reflective artwork on the outside will enable you to be visible even during the darker swim and swimrun adventures!

    Volume: 13 liter
