Almost every Parke T-shirt is 100% cotton — almost. There's one confirmed exception worth knowing before you assume the whole lineup is uniform, and it changes how that specific style should be washed and worn compared to the rest of the range. Here's the actual fabric picture, style by style.

Confirmed Fabric Composition, Style by Style

Directly from Parke's own official product listings: the Core T-Shirt is 100% cotton. The Striped T-Shirt, across its various colorways, is also https://parkeus.com/ 100% cotton. The Long Sleeve Core T-Shirt follows the same core fabric philosophy as the short-sleeve version.The exception: the Ribbed Short Sleeve T-Shirt is made from 80% cotton and 20% polyester, confirmed directly on its official product page  a genuinely different composition from the rest of the core lineup. That polyester content isn't incidental. Ribbed knit fabric needs some stretch-and-recovery capability to hold its close, fitted shape without sagging, and a small polyester percentage helps the ribbing do that more reliably than pure cotton would on its own.

Why This Distinction Actually Matters

Assuming every Parke tee is 100% cotton leads to two practical mistakes. First, care expectations shift — the ribbed style, with its polyester content, resists shrinking more than the all-cotton pieces, meaning it can handle slightly less careful laundering without the same shrink risk. Second, fit behavior differs — a ribbed, blended fabric hugs closer to the body and holds that close fit through wear, while the 100% cotton pieces drape more loosely and soften more dramatically over repeated washing.Check the specific listing before assuming one fabric rule applies across the whole T-shirt range.

Fabric weight claims for Parke's T-shirts follow the same pattern seen across the rest of the brand's catalog — real disagreement between sources, with nothing officially confirmed. One source cites a lightweight-to-midweight range of 180-240 GSM. A separate source claims something considerably lighter, closer to 100-120 GSM. Neither figure comes from Parke's own confirmed specifications.What can be said with more confidence, based on general product description language across multiple sources: the fabric is generally positioned as sitting between a thin, disposable fashion tee and a heavy, boxy gym shirt — not the lightest option available, not the heaviest either. Treat any specific GSM number for this category the same way you would for the brand's hoodies: an estimate, not a verified spec.

Construction Jersey Knit, Ribbed Collar

The core tees use a standard jersey knit construction — the same basic stretchy, single-layer knit found on most casual cotton T-shirts, which is what gives the fabric its soft, slightly stretchy hand feel. The crew neckline across the lineup uses ribbed trim specifically to help the collar hold its shape after repeated wear and washing, rather than stretching out and gaping the way an unreinforced neckline eventually does on a cheaper tee.

How Fabric Choice Should Affect Your Care Routine

For the 100% cotton pieces — Core Tee, Long Sleeve Core, Striped Tee — cold water washing and air drying or low-heat tumble drying matter more than they would on a blended fabric, since there's no polyester content to resist shrinkage. For the Ribbed Short Sleeve style specifically, the 80/20 blend offers a bit more forgiveness on wash temperature, though sticking to the same cold-wash habit is still the safer default across the board, since it protects color and print quality regardless of fiber content.

Quick Reference

Final Thoughts

Most of Parke's T-shirt lineup is genuinely, consistently 100% cotton, but the Ribbed Short Sleeve style breaks that pattern with a confirmed 80/20 cotton-polyester blend, built that way specifically to help the ribbed construction hold its close fit over time. Fabric weight remains an unsettled question across sources, so don't lean too heavily on any specific GSM figure floating around. What is settled: check the specific listing's fiber content before assuming a uniform care and fit routine applies to every tee in the range.
