This short-sleeve crew neck features a technical grid-like texture, raglan sleeves for enhanced mobility, and flatlock seams to minimize chafing during active use. Designed as a versatile athletic piece, it works perfectly as a standalone shirt for warm-weather hiking or as a moisture-wicking foundation for layering in cooler conditions.
