UMMY ONE Side Story

Meet Prussian Blue
It took two years from conception to launch of the UMMY carbon fin. The number of sample fins required was several dozens of sets... UMMY does not have its own manufacturing plant, so they negotiated, planned and developed with fin manufacturers around the world, and finally made a fateful encounter with Prussian Blue, a top fin manufacturer in Taiwan.
Technical ability x Execution ability
The reliable quality of the fins developed by Prussian Blue, the innovativeness of the foot pockets developed by the company, and above all, UMMY's willingness to flexibly respond to the high demands that UMMY has for fins were the deciding factors that led UMMY to enter into a strategic partnership with the company. It was at this moment that UMMY was convinced that the best fins could be made by combining UMMY's execution ability to meet customer needs with Prussian Blue's technical capabilities.


UMMY's fin
UMMY aims to create fins that will satisfy all divers who love diving, including free divers, skin divers, and spear fishers. In order to achieve this goal, we spent a year trying and testing everything from design, color variations, functionality, foot pockets, and price to a complete review, and we were able to successfully develop fins that UMMY owners themselves were satisfied with.
Origin of UMMY ONE
ONE is a word that means starting from scratch, and "Ichiban" is a word that means the top or the peak. We named it UMMY ONE with the desire to always keep moving forward without forgetting the first step we took and to aim to become the most beloved fin in the world in the future.

UMMY ONE Shorts are the most important aspects

Fins are all about lightness. The UMMY ONE Short weighs only about 350g. The light weight has made it possible to greatly reduce the burden on divers. You will feel the difference in all skin diving and free diving training. You will be surprised at how light it is when you pick it up. In addition, the special processing of the foot pocket makes it float on the water surface, so you no longer have to worry about sinking it in the sea.

The UMMY ONE Short is made by bonding carbon with Plussian Blue's unique special technology. This results in a fin that provides maximum efficiency and maximum propulsion. The blade diameter is 60 cm and the blade angle is 26°. The UMMY ONE Short places the utmost importance on efficiency and ease of handling, and has a blade length that allows maximum efficiency with one kick, and a 26° angle that can be used for all dives, including parallel movement on the surface and underwater, and vertical diving, to meet the needs of many divers.

Although it is a short fin, it has a propulsive force comparable to that of a long fin, and once you use it, you will be impressed by its ease of handling. This fin is suitable for those who value ease of handling, travelers who move around a lot, instructors, photographers, dolphin swimmers, and those who take off and put on a lot of things during boat swims.

UMMY products must always be stylish. UMMY ONE uses the UMMY symbol mark for the blade tip and the carbon laminate design on the back. The blade cut is perfectly balanced with the symbol mark to create a beautiful, one-of-a-kind fin.

The new Foot Pocket X1 from Prussian Blue is a well-balanced trinity of art that is easy to wear, comfortable to wear, and a good kicking sensation. The foot pocket is soft and stretches very well, so you can wear it with bare feet or 2mm socks in the same size.
