Modern sport function. Everyday ease. Jack Adams fit at its best.

The Athletica Trunk is built for guys who want a clean, athletic profile with the added convenience of a functional fly. Cut in a low‑rise silhouette with a sport‑length leg, it delivers that signature Jack Adams balance of support, mobility, and minimal bulk.

Crafted from extra‑soft cotton rib with true 4‑way stretch, the fabric moves naturally with your body—staying breathable, flexible, and close‑fitting throughout the day. The rib texture adds subtle structure, helping the trunk maintain its shape while still feeling lightweight and smooth against the skin.

A low‑profile 1" waistband keeps the look sleek and modern, sitting flat without digging.
