Tribal KROSS-S

Unlock Freerace Power. Speed, Drive and Acceleration. No cams required.

Unlock Powerful Freerace Performance

Kross is TRIBAL's modern crossover sail platform: one sail range including Wave, Freeride and Freerace. One DNA, scaled to your conditions: Kross-W in small sizes for Power Wave, Kross-X in mid sizes for Freeride and Kross-S in larger sizes for Freerace.


Your smallest sail should feel controlled. Your mid-size sail should feel balanced. Your largest sail should feel powerful. That’s exactly how the Kross range has been built.


Kross-S is tuned for larger sizes where power, drive and top-end speed become essential. It bridges the gap between Freeride simplicity and Freerace performance. It unlocks Freerace speed and drive.

Frequently Asked Questions

Is Kross three different sails?
The Kross range is one platform tuned by size range. It's Tribal’s modern crossover sail platform. From small wave sizes to large Freerace power. One DNA, scaled for your conditions: Wave, Freeride and Freerace. Your smallest sail should feel controlled. Your mid-size sail should feel balanced. Your largest sail should feel powerful.

That’s exactly how Kross is built. One architecture. Three performance zones. One consistent evolution.

Instead of separating Wave, Freeride and Freerace completely, Tribal developed one intelligent crossover platform, scaled by size and tuned per range.

Kross scales performance by size:
• Wave control and stability in small sizes (4.7 - 5.3)
• All-round Freeride balance in mid sizes (5.8 - 6.4)
• Freerace power, speed and drive in large sizes (6.8 - 8.4)
Which version of KROSS should I choose?
Choose your Kross sail based on size and conditions. Small for control and wave-focus. Mid for balance. Large for speed and drive.

🟣 Kross-W → Small Sizes → Crossover / Power Wave
🔵 Kross-X → Mid Sizes → Crossover Freeride
🔴 Kross-S → Large Sizes → Crossover Freerace

Kross is built to give you:
• Logical performance scaling
• Stable trim
• Wide wind range
• Consistent feel across your quiver

If you want one platform that evolves with wind strength, Kross delivers.

Is it suitable for beginner Freeride?
Kross-S is not for absolute beginners or regular Freeride use. It is ideal for progressing riders who plane confidently and wish to make the step towards Slalom performance but without the hassles of rigging a camber sail.

KROSS can be used for bump & jump, but it is designed primarily for No-Cam Freerace and Speed sailing
Which mast should I use in my Kross sails: SDM or RDM?
KROSS has been designed for use with both RDM and SDM masts.

The narrow mast sleeve allows for easier rigging in the smaller sizes with RDM masts; the larger sizes are perfectly suited for use with SDM but RDM can be used as well.

SDM will guarantee a more direct feeling as RDM on the other hand will give the sail a softer feeling, both combined with perfect performance, control and stability.
Why size-based tuning makes sense?
Wind strength changes. Board volume changes. Sailing style changes. Your sail should adapt logically.

Kross scales performance by size:
Small = Control
Medium = Balance
Large = Drive

This creates a consistent feel across your quiver. You don’t switch personality when you switch size. You just scale power.
