Performance
Lightweight & Efficient
At around 602 g, this paddle sits among the lighter carbon touring paddles on the market — a real advantage for long days on the water. The foam-core blades boost buoyancy, making forward strokes feel effortless and smooth, which reduces shoulder fatigue over time.
Grip & Feel
The shaft features a textured grip that’s more assertive when dry but becomes comfortably tacky when wet, helping with control without feeling rough. Some paddlers say it takes a session or two to get used to compared with smoother shafts, but once dialed in it’s very confidence inspiring.
Posi-Lok Ferrule System
The Posi-Lok ferrule allows quick, secure adjustments of feather angle — ideal if you share the paddle between paddlers or adapt it to evolving wind/sea conditions. It’s solid and feels precise.
Construction & Durability
One of the standout features of the Tetra is its Lam-Lok™ technology, which uses aramid stitching through the blade edges and internal foam to dramatically reduce delamination and impact damage — a common weak point in ultralight paddles.
This isn’t just marketing: independent testers have commented that this construction appears to bridge the gap between race-level lightness and real-world durability.
Practical Use Cases
⚓ Touring & Sea Kayaking: Excellent — smooth tracking and fatigue-reducing feel make it ideal for long flatwater days.
Technical Strokes: Reinforced blade edges and seamless construction support strong control when you need precise directional strokes.
All-Around: It’s versatile, but aficionados might prefer specific blades for whitewater or very high-angle paddling.
What Our Customers Say
Many paddlers love the “disappearing feel” — where the paddle feels almost effortless and natural in hand. Compared to other high-tier paddles like the Werner Kalliste, the Tetra’s lightness and edge protection are often highlighted as advantages, though preferences can be subjective.
