This lightweight long-sleeve t-shirt features a classic sporty raglan construction with contrasting navy blue trim on the crew neckline, sleeve cuffs, and iconic double stripes running down each sleeve—evoking athletic heritage styling. Made from soft, breathable cotton-blend fabric, it offers comfort for daily wear while maintaining a clean, minimalist aesthetic. The relaxed fit and subtle color-blocking (light blue body with navy accents) make it versatile for layering or standalone wear in transitional seasons. Ideal for casual outings, school uniforms, or athleisure looks, the design prioritizes functionality and understated style without overt branding. The garment is photographed flat against white background with watermark '广州老白号服饰商行 (个人独资)', indicating it's likely a generic OEM/ODM production item rather than a designer brand. No visible logos, tags, or distinctive brand markers are present—confirming unbranded status. Suitable for spring and fall wear, this piece balances sportiness with everyday practicality.
