The nattily named SP770GTRSLK is Santini’s top reverse-zip tri suit. Made from a Lycra/elastane mix, it’s close-fitting and aero but moves well in all three disciplines. The reverse zip has a nice long tassel that’s easy to pull up and down, while the thick gel pad is comfy without being too cumbersome when running.
With no mesh or front ventilation, the suit gets hot and sweaty quite quickly, and while the silicone-backed leg grippers hold comfortably, the scratchy folded seams on the arm holes left angry red marks after swimming. The lack of pockets means it’s for short races only. As with most Italian gear, it’s best to size up.
