ALPHX Athletic Fit Loungewear – Room to Move, Built to Last

ALPHX Athletic Fit Union Pants are engineered with added room through the thighs to support powerful legs without compromising a clean, tailored silhouette. Rather than loosening the garment overall, Athletic Fit redistributes fabric where movement demands it most—relieving restriction while maintaining controlled leg openings, balanced seat dimensions, and all-day comfort. Designed for breathable performance, natural support, and unrestricted motion, they deliver a stable, refined fit that moves with your body and stays smooth under clothing.

Streamlined Strength. Engineered Mobility.

ALPHX Athletic Fit Union Pants are engineered for men who need extra room through the thighs without sacrificing a clean, tailored silhouette. Designed to relieve restriction where movement demands it most, they deliver breathable comfort, natural support, and all-day ease—without pulling, binding, or excess fabric.
