Why We Love It
Built for triathletes chasing a faster transition without sacrificing all-day comfort, the Core Tri Aero Jersey pairs a relaxed athletic fit with moisture-wicking performance. High-performance Italian fabric manages heat and sweat through the bike and run legs, while a full-length YKK zipper dials ventilation up or down on demand. Dual rear pockets keep nutrition and race essentials secure, and built-in UPF 50+ protects through hours in the sun. Jet Black is one of four core colourways in this run.

Talk Nerdy To Me
The jersey blends three different fabric weights to match the job each panel does. The front body runs a heavier 240g/m2 blend of 80% polyester and 20% elastane for structure and compression through the torso, while the back body and sleeves switch to a lighter 115g/m2 blend at 85% polyester and 15% elastane so heat and moisture actually move rather than sitting against the skin. Ventilated sleeve panels add airflow and a small aerodynamic benefit while doubling as UPF 50+ sun protection for a jersey you'll wear well past T2. At the front, a YKK semi-auto-lock zipper lets you dial venting up or down without it slipping open mid-ride, backed by a no-sew zipper garage, a bonded rather than stitched zipper channel that removes the seam most likely to rub under a wetsuit or hydration pack.

Seamlink stitching runs through the high-stress zones to add stretch and strength without the bulk of a standard flatlock seam, and Italian-made silicone grippers along the hem keep the jersey in place through the bike-to-run transition without a tight compression band digging in on a long day. The fit itself is relaxed rather than race-compression, built for the hours of a longer event rather than a sprint. Dual rear pockets are sized to carry gels, a spare tube, or race nutrition without bouncing.

Fast Facts
- Three-weight Italian fabric build: 240g/m2 front body for structure, 115g/m2 back and sleeves for breathability
