The high-visibility orange color will allow you to be seen even from a long distance or on cloudy days. If you ever start to drift into more treacherous waters, this ultra-bright color can be easily seen by swimmers, boaters, and lifeguards alike. The watertight compartment with its clip closure allows you to securely store your items without any water damage. The adjustable strap adapts to the shape of your body so that the buoy stays put and will not bother you. In addition, its small size will allow you to enjoy swimming without restrictions.

The FUZION triathlon wetsuit meets the needs of triathletes who want both buoyancy and flexibility. It combines these two characteristics in a very versatile suit. It is made entirely of Yamamoto #38, #39 and #39 AERODOME neoprene, with thicknesses ranging from 1.5 to 5 mm depending on the body part.

Triathletes for whom buoyancy is as important as flexibility will be particularly satisfied with this model.

It features a reverse back zipper that closes from top to bottom, requiring external assistance to close, but allowing for quicker removal of the suit when exiting the water at T1

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!
