This is a white long-sleeve training jersey by WellDone, the official technical apparel partner of Spanish La Liga club Club Atlético Osasuna. The jersey features a clean, minimalist sportswear aesthetic with black 'WellDone' branding on the left chest and a large inverted 'WellDone' logo across the front torso (likely for photo display or packaging). A detailed embroidered club crest—featuring Osasuna’s traditional shield with lion motif and crown—is positioned on the right chest. The garment has a classic crew neck, ribbed cuffs and hem, and appears to be made from lightweight, breathable synthetic performance fabric suitable for training or casual streetwear. Its oversized fit aligns with contemporary athleisure trends. Ideal for fans supporting Osasuna or those seeking functional yet stylish sport-inspired tops. Perfect for daily wear in mild to warm weather, gym sessions, or as a statement layer under outerwear. The design balances club identity with modern minimalism, making it versatile across casual and sport contexts.
