[New Product] Announcement: Sleeveless Model Now Available

Thank you for your continued support of CORE SHIELD®.

As of today, June 30, 2026, we have launched the CORE SHIELD® Inner Sleeveless Model.

The sleeveless model is designed to combat mid-summer heat; it firmly covers the core with our special Trubeaute® fiber, which blocks over 76% of near-infrared rays (*based on third-party laboratory testing of the fabric), while allowing for effective heat dissipation by keeping the arms exposed. It is also recommended as an undershirt for occasions where you prefer not to have sleeves visible, such as under a golf polo shirt.

We have also provided a guide on our column page to help you choose between this and our long-sleeve model.
