It all comes down to strokes and kicks
- Strong strokes and rapid kicking do most of the work
- Flippers for the feet have been the only real option
- The rest of the body adds little push against the water
A fin for the whole body
- A torso fin runs from the wrist to the waist like a large wing
- Leggings fins turn your legs into two halves of a paddle
- Designed to work with every kick, stroke and body roll
How it works
Put on the torso fin
Slip into the vest harness and fasten the belt. The fin runs from your wrist to your waist.
Strap on the leggings
Fasten the leggings fins from mid-thigh to above the ankle, then add your regular flippers.
Push against the water
Swim as usual. Your arms, torso and legs are all designed to help move you through the water.

Questions, answered
Can I buy LimpKenFin now?
Not yet. LimpKenFin is a patented concept that is heading into development, and it isn't for sale. Join the interest list to follow its progress. It's free and you can unsubscribe anytime.
Are these photos of the real product?
Not yet. The images are 3D renders and stills from a computer-generated product video, and the people shown are not customers. The final product may differ.
How much will it cost?
Pricing hasn't been set. Interest list members will hear first.
What are the parts?
LimpKenFin is a two-piece set. The LimpKenTorsoFin wears like an aquatic vest and runs from the wrist to the waist, creating a large wing-type fin. The LimpKenLeggingsFin wears like chaps and runs from mid-thigh to just above the ankle. Combined with a pair of flippers, they make a full-body propulsion system.
How does the torso fin keep its shape?
An elastic tension cord runs from a handle in your hand to braces at the wrist, elbow and waist. The braces hold the cord away from your body so the fin stays taut, which is designed to give you more control of movement.
Who is it for?
Recreational swimmers, snorkel and scuba divers, and anyone who wants more options when it comes to swimming equipment.
Can I dive into the water wearing it?
No. LimpKenFin is meant for swimming, snorkeling and scuba diving, not for diving or jumping into the water from a rock, boat or cliff.
Is LimpKenFin patented?
Yes. LimpKenFin is protected by U.S. Patent No. 9,849,339, "Body Fin for Swimming," granted to inventor Donald Stanley on December 26, 2017.

Our Story
The LimpKenFin was born from the idea that the human body is not suited to push against the density of the water to move through the water. The Ah Ha! Moment came when a young boy was drifting in the center of an innertube in a river. He held his legs together and swirled them 360 degrees beneath him. To his surprise he spun like a top, there was no resistance. The idea that with the right equipment a human could push against the density of the water to slide through the water was born. The LimpKenFin is the end result of visualizing what it would take to create equipment that would transform a human body into its aquatic equivalent.
