Core Signature Runner Boxer White

Built like runner shorts. Worn like a Sunday. Borrowed from classic military runner shorts and cut for the weekend. The Core Runner Boxer is loose where you want air, shaped by signature side insets so it never reads boxy, and soft 100% cotton everywhere. Fabric 100% Cotton. Soft, breathable, and natural against the skin — the boxer you sleep in, lounge in, and forget you're wearing. Fit & Silhouette Men's cotton runner boxer, semi-fitted and mid-rise — sits at the natural waist with a 3" inseam that frees the leg without the flap of a traditional boxer. Side Insets Signature side insets shape the leg opening the way runner shorts do — a cleaner line and more room to move. Fly Functional button fly — the classic detail, kept because it works. Leg Openings Runner-style openings move air freely and never cling to the thigh. Waistband 1.5" exposed elastic waistband with the new signature C-IN2 logo in repeat. Fit note True to size. For a looser fit, go one size up. Care Machine wash. Imported. Core C-IN2's foundation — every essential silhouette, cut in soft, breathable 100% cotton that feels better the longer you own it. The drawer you build once and reach for every day.
