Style: Long-sleeve polo shirt for men — a smart-casual piece combining the classic polo collar with full sleeves.
Fabric & feel: Expect mid-to-heavy weight knit fabric (more substantial than a T-shirt), comfortable for cooler evenings and layering.
Collared with placket: Polo collar with usually 2–3 buttons, giving a refined finish.
Sleeves: Full length sleeves often finished with ribbed cuffs (or a subtle hem) for a tidy appearance and to hold shape.
Fit & construction: Good quality long-sleeve polos maintain clean stitching at shoulders, good collar shape (non-floppy), straight hem (sometimes split side hems) and minimal puckering at seams.
Colour & polish: Solid rich colours or subtle textures show better quality; fewer flashy prints = more versatility.
Brand example: On IMOPAS’s site there is listed “High quality Polo for men” among their offerings.

✅ Why this would count as “high quality”
Durable fabric weight: A thicker knit means longer lasting, less prone to waving or becoming see-through.
Good collar construction: It should sit up nicely; collar stays or reinforced collar band is a plus.
Clean finishing: Well-stitched seams, no loose threads, cuffs and hem that retain shape after wash.
Versatility: A long-sleeve polo bridges the gap between purely casual and smart-casual — you can wear it under a blazer or with chinos or denim.
Local availability: Since IMOPAS lists it among their “high quality” men’s polos, it indicates intent towards a premium offering.
