Hydrus Click-In Fin — The Easiest, Smartest SUP Fin on the Water

Now Modified to Stay Locked In — Clicks In, Doesn’t Click Out.

⭐⭐⭐⭐⭐
“Best fin I’ve ever used — installs in seconds, tracks beautifully, and never falls out mid-paddle. Absolute no-brainer upgrade.”
— Matt D.


Meet the Fin That Changed the Game

No tools. No screws. No fumbling with tiny parts at the shore.
The Hydrus Click-In Fin is the simplest, fastest, and most intuitive fin system in the paddleboard world — now re-engineered so it clicks in securely and stays there until you’re ready to remove it.

Designed for paddlers who value speed, convenience, and real-world dependability, it’s the perfect balance of ease and performance — and it fits virtually any US-style 10" fin box.

🧠 Smart Design. Real Results.

This isn’t a gimmick fin — it’s the evolution of simplicity.
We refined the original click-in system to fix its only flaw: the occasional “pop out.” The result is the same fast install, but with Hydrus reliability — click it in once and it’s not going anywhere until you’re done.

“It’s one of those upgrades that makes you wonder why all fins aren’t built this way.”


🧼 Maintenance Tip

If your fin ever sticks after use:
Sand, salt, or debris can jam the ball-bearing mechanism. Just rinse the fin box, clear any grit, and test before reinstalling. A quick rinse keeps it smooth for life.


💥 Add It to Your Setup

Bundle this fin with your next Hydrus board or grab a spare for your travel kit.
It’s small, smart, and seriously satisfying — the fin upgrade that makes every paddle smoother.
