Polo shirts are most often made from knitted cotton piqué, though cotton-polyester blends, jersey knit, and performance polyester are also common.
The knit structure affects how the shirt breathes, drapes, and holds its shape. Understanding the fabric helps you pick a polo that fits your use — whether weekend yard work, golf, or casual Friday.
What Is Piqué Fabric?
Piqué is the classic polo fabric: a double-weave knit with a waffle texture on one side, created by the space between layers. The raised pattern forms small air pockets that improve airflow, making piqué more breathable than smoother knits. It’s also structured, holds shape well, and resists wrinkles — hence its dominance from tennis courts to business-casual dress codes.
Piqué shirts usually use 100% cotton or cotton-polyester blends. Cotton provides softness and breathability; polyester adds durability and faster drying. The result looks sharp out of the wash and stays that way.
What Other Fabrics Are Used for Polo Shirts?
Jersey knit is the smooth, flat-knit fabric on casual T-shirts and some polos. It drapes more softly, feels smoother, and reads as more casual than piqué.
Interlock knit is a heavier double-knit made from two jersey layers knitted together. It has a smooth face on both sides, a soft handfeel, and more structure — sitting between jersey and piqué in formality.
Performance polyester fabrics, common in athletic polos, are engineered for moisture management and quick drying. For golf in summer heat or active use, polyester or polyester blends outperform cotton. Synthetic fibers also resist stretching and fading better.
Fabric Weight And Quality: What To Look For
Fabric weight, measured in grams per square meter (GSM), tells you how a polo will wear. Standard polos commonly use cotton, CVC, or polyester piqué in the 180–220 GSM range; heavier versions run 200–240+ GSM. Higher GSM means a more substantial, structured shirt that drapes well and resists clinging; lighter fabric feels airier but is thinner and less durable.
Yarn count also signals quality. Finer yarns, like a 32s combed count, produce a smoother handfeel. Product pages often list specs like “100% cotton piqué knit, 32s combed yarn, 230gsm.” Premium versions go further: one men’s polo uses 100% Supima Cotton for softness and strength; another uses 100% organic cotton at 210 g/m² with long-staple fibers.
A quick rule: for a structured, classic polo, choose heavier piqué (200–230 GSM). For a soft, drapey feel, opt for jersey knit or lighter-weight piqué.
Common Mistakes When Choosing Polo Fabric
Three mix-ups trip up most buyers.
Confusing cotton content with knit type. A “100% cotton” label tells you the fiber, not the weave. Some cotton polos are jersey, some are piqué, and they feel completely different. Always check the knit structure.
Assuming all polos breathe the same way. Cotton piqué absorbs sweat and feels comfortable in moderate conditions; polyester wicks moisture and dries fast. Pick based on your use.
Treating one product page’s specs as universal. GSM, yarn count, and width vary by manufacturer. A 230gsm piqué from one brand may feel different from another’s. Verify specs per product.
One more note: fiber content can vary by color within the same shirt model. A heather gray polo might be 90% cotton and 10% polyester while the solid black version is 100% cotton. Verify the specific colorway.

| Fabric | Key Traits | Best For |
|---|---|---|
| Cotton Piqué | Textured, breathable, structured, wrinkle-resistant | Classic polos, everyday wear, business casual |
| Cotton Jersey | Smooth, soft, drapes well | Casual, relaxed looks |
| Cotton Interlock | Smooth both sides, heavier, soft handfeel | Mid-weight, soft-touch polos |
| Performance Polyester | Moisture-wicking, quick-drying, durable | Golf, sports, hot-weather activity |
| Cotton-Polyester Blend | Balances cotton comfort with synthetic durability | All-purpose, lower-maintenance wear |
Cotton polos can shrink in hot water or high-heat drying, so check the care label. When in doubt, wash cold and hang dry.
FAQs
Is piqué the same as cotton?
No. Piqué is a knit structure, not a fiber — it describes the textured waffle-like weave. Piqué polos are most commonly cotton, but can use blends or other fibers. The label tells fiber content; the piqué structure tells how it’s knitted.
What GSM is a good polo shirt?
Standard polos use 180–220 GSM; heavier versions run 200–240+ GSM. Higher GSM means more structure and better drape; lighter feels airier but is thinner and less durable.
Why do my cotton polos shrink?
Cotton fibers contract with heat and agitation. Washing hot or drying on high tightens fibers. Cold water and hang drying prevent shrinking. Preshrunk labels reduce but don’t eliminate shrinkage.
