The Flow part of the Selle Italia SLR Max Gel Flow Saddle is its most distinctive feature and will probably be its key selling point. If you want a saddle whose anatomic cutout alleviates pressure where you don't want it, then here you go. No one in the game does it as well or as dramatically as Selle Italia.
A bit of grippy material runs down the middle portions that remain in order to keep you from sliding about during long, in-the-saddle grinds. Gel padding keeps the contact with your sit bones soft but not bouncy. The shell's 10% carbon construction is stiff enough to support well, but elastomer inserts between the rails mean this won't translate to undo road noise coming up through your seatpost.
The Selle Italia SLR Max Gel Flow Saddle is available in the colors Black and White.
