UB Core
The UB Core is the ultimate everyday essential—a premium unisex t-shirt built to last. Crafted from 100% ring-spun cotton with a substantial 6.1 oz weight, it delivers the perfect balance of structure and softness. The garment-dyed finish gives each piece unique character, while the relaxed fit works with any style. Double-needle construction reinforces every seam, twill-taped shoulders and neck add durability, and the topstitched collar keeps its shape wash after wash. This is the tee that does it all—comfortable enough for all day wear, tough enough to become a wardrobe staple.
