Fabric & Construction +
  • 310 GSM / 9.1 oz ring-spun cotton — no synthetic blends
  • Double-needle stitching at sleeves and hem
  • Taped neck for retained shape and comfort
  • Reinforced shoulders — holds structure wash after wash
  • Pre-shrunk for true-to-size fit after laundering
  • Ribbed collar with retained structure
Fit & Sizing +

Modern oversized fit with drop shoulders. Not boxy, not slim — structured proportions that work across body types. The drop shoulder extends the sleeve slightly past the natural shoulder point, creating a clean, relaxed silhouette.

When in doubt, size up for a more relaxed drape. Size down if you prefer a fitted feel.

The Birrd Standard

Why
Heavyweight?

310
GSM — Why It Matters
GSM (grams per square meter) is fabric weight. It's the number the industry uses to describe how dense, how substantial, how real a shirt feels. Most "premium" tees sit at 150–180 GSM — they're soft and packable, but they pill, they stretch out, they go transparent under a bright light. At 310 GSM, the birrd tee has nearly double the material. You feel it when you lift it off the shelf.
9.1
oz / yd² — The Feel Test
Ounces per square yard is how American markets measure the same thing. A 9.1 oz tee is what workwear was built on for a century — before "athletic fit" and "moisture-wicking" made garments thin by design. That density translates directly to durability: fewer pills, better drape, slower color fade, and a shirt that doesn't look like you've owned it for two years after one wash cycle.
0
Synthetic Blends
Polyester is cheap and adds structure cheaply. It also makes fabric feel synthetic, pills faster, and traps odor. Ring-spun 100% cotton combs and twists the fibers into a tighter, smoother yarn — more surface area, better dye absorption, softer against skin, and more breathable than any blend. The extra cost goes directly into the material, not the marketing.
50+
Washes — The Real Test
Most tees are designed to look good in a product photo and feel good at first wear. The birrd tee is designed to be better at fifty washes than at one. The pre-shrunk treatment means the fit stays true. The reinforced double-needle stitching means seams don't open. The taped neck means the collar holds its shape. Heavy upfront investment in material pays dividends across years of use.
How 310 GSM compares
140–180
Lightweight
Fast fashion tees, athletic wear. Soft, packable, transparent. Wears out in a year.
180–240
Midweight
Most "premium" branded tees. Decent quality. Starts to pill after 20–30 washes.
280–320
Heavyweight
Workwear density. Structural integrity. Holds shape and color across years of wear.
320+
Ultra Heavy
Niche and specialty. Stiff until broken in. More workwear than everyday wear.

310 GSM sits at the top of the heavyweight category — heavy enough to have real structural integrity, without crossing into the stiff territory of specialty workwear. It's the optimal weight for an everyday tee that you actually reach for.

Size Guide

Modern oversized fit with drop shoulders. Measurements in inches. For reference only — actual garment measurements may vary slightly.

Fit tip: This is an oversized, drop-shoulder cut. If you're between sizes, size down for a fitted feel or stay true-to-size for the intended relaxed silhouette. 3XL buyers with a broader chest may find 2XL still fits with a slightly more structured look.
