Why We Love It
Built for triathletes chasing a faster transition without sacrificing all-day comfort, the Core Tri 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 BYOB styling means you wear your own sports bra underneath.
Talk Nerdy To Me
The jersey is cut from a high-performance Italian fabric chosen for cooling and moisture management rather than a generic wicking blend, so sweat moves off the skin and evaporates instead of sitting against it through the run leg. Ventilated panels through the sleeves improve airflow and add a small aerodynamic benefit while doubling as UPF 50+ sun protection, useful on a jersey you'll wear well past T2 in full sun. At the front, a YKK semi-auto-lock zipper lets you dial venting up or down without it slipping open mid-ride, and Zoot backs it with 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, and it's designed BYOB, Bring Your Own Bra, so you fit your own sports bra underneath instead of relying on a built-in shelf. Dual rear pockets are sized to carry gels, a spare tube, or race nutrition without bouncing.
