Trespass Ceithir Active T-Shirt

Product Insights & Style Tips

Effortless gym to street cred starts with the Trespass Ceithir Active T-Shirt. The knitted fabric blends 93 percent polyester with 7 percent elastane for a breathable, lightweight feel that moves with you. A dipped hem and taped crew neck create a clean line, while raglan short sleeves read sporty and easy for layering under a hoodie or jacket when the day shifts.

With a shaped waist, it skims the middle without clinging, sitting nicely over jeans, leggings, or joggers. The moisture wicking, quick dry performance keeps you comfortable through a workout or a long commute, and the raglan cut gives you freedom of movement from warm-ups to cool-downs. Lightweight and flexible, it layers smoothly under outerwear or sits loose on top for a relaxed, athletic everyday look.

Trespass leans into the current mix of performance basics that look as good as they feel. Ceithir sits at the intersection of gymwear and city wear, a versatile staple that pairs with everything from high rise denim to sporty skirts, captured in a clean, understated silhouette.
