The Duotone Select Concept Blue is the eco-friendly version of the renowned Select SLS, delivering an exceptional freeride experience for riders committed to sustainability.
Key Differences: Duotone Select 2025 vs 2026
- 
Bottom / Under-shape - 
2025 → Uses the established bottom shape (not explicitly “double concave”) with good damping and smooth landings in the SLS version. 
- 
2026 → Introduces a Double Concave Bottom in the Select SLS, which is meant to act like a shock absorber, giving smoother rides in chop, softer landings, and more grip. 
 
- 
- 
Rails / Edge Design - 
2025 → Standard rail design; good grip and carving, but with more traditional geometry. 
- 
2026 → Adds Angled Rails in the Select SLS to improve upwind performance and edge control. 
 
- 
- 
Flex / Carving / Feel - 
2025 → Incorporates Space Flex, asymmetrical deck, and proven construction for a balanced freeride feel (comfort + performance). 
- 
2026 → Claims upgrades to Space Flex for smoother carving, and with the bottom + rail changes, the feel is tuned more for comfort in chop and sharper control. 
 
- 
- 
Construction / Materials - 
Both years use premium materials (wood core, Textreme Innegra, Biax Carbon in the SLS version) to balance lightness, strength, and damping. 
- 
2026 retains the SLS construction and upgrades around that platform, rather than switching to a totally different material set. 
 
- 
- 
Performance Gains / Marketing Claims - 
2026 is marketed as “faster, more comfortable, and smarter” than 2025, thanks to the new bottom shape and rail tweaks. 
- 
The Double Concave is described as delivering extra grip and softer landings, especially in rough water.
