ÖTILLÖ Products and Merchandise

ÖTILLÖ Products to help you perform

The ÖTILLÖ Swimrun ethos: To try to adapt to nature, not conquer nature.
Over the past years we have worked very hard to develop the best and most versatile swimrun products together with our partners. These are based on that we do swimrun in different environments, with different capabilities.

ARK Swimrun wetsuits and gear

ARK Sports focus’ on endurance sports, with its roots in swimrun, where they have a lot of experience. Together we work in close collaboration with the world’s best swimrun athletes and the international swimrun community. Athletes are our biggest inspiration and their input is invaluable for the development of the best equipment.

ARK Vigg™

Our most lightweight suit. Designed for warmer
climates and sprint races where less insulation
and buoyancy are needed in favor of light weight
and speed.


Incredibly warm and buoyant suit for cold
conditions and choppy waters. Increased storage,
improved insulation  and an updated leg cut for
those long races and tough courses.


For you to wear under your wetsuit to increase
insulation,but you can also use it separately when
running. With 4 separate pockets you can also
bring energy, a phone or whatever you need
on your adventures.


ARK Keel+™

This is the most buoyant pull buoy ever made
and the largest in our KEEL™ family. Ultralight
design, and with its 55 Newton buoyancy effect,
it will lift you as never before.


Carrying gels, soft flasks, and other extra
equipment is very individual. Here you have
two big pockets for carrying a phone, gel
or whatever makes you happy!

ARK Blades™

Designed and developed with the ambition
to produce the fastest swimrun paddle in the
world. Hydrodynamic, lightweight and durable

UMARA are specialists in nutrition/energy for endurance sports. With the help of science, experience from athletes, and their own ability to weave theory with practice, they develop optimized sports nutrition to help you perform at your individual peak.

Creatine is most effective for strength and explosive activities, beetroot juice increases blood circulation and oxygen transport. Sports drinks, energy bars, and gels are a good energy source when the intensity is high and you want to perform at your best. Umara’s sports drink contains an optimized carbohydrate mix, BCAA, and electrolytes that help you cope with more intense or longer training sessions. We have supplements specifically for athletes such as fish oil or vitamin D3 that contribute to maintaining normal muscle function. To recover after a workout, try our tasty protein bars or recovery drinks.
