Detailed Breakdowns
Why Rib Collars Matter
Rib collars are essential for garment longevity and comfort. The ribbed texture provides structural support and durability to the neckline, helping prevent the collar from stretching or losing its shape over time, especially with repeated wear and washing. The elasticity of ribbed fabric allows it to stretch and recover, maintaining a snug fit around the neckline without becoming loose or baggy. This prevents the dreaded "bacon neck" that occurs when the collar stretches out, ensuring the garment maintains its professional appearance.
The Importance of Taping
Shoulder-to-shoulder taping and neck taping significantly enhance garment durability. Neck tape reinforces the collar area, preventing stretching or sagging over time while adding stability and structure to the garment. Taping strengthens seams by dispersing force when fabric is under load, reducing the chances of seam separation. This technique is particularly important in performance clothing, where fabric is subject to more stress and strain due to physical activity.
Ring-Spun Cotton Advantages
Ring-spun cotton offers superior quality compared to regular cotton. Ring-spun cotton is made by twisting cotton fibers tightly, creating longer, stronger strands that are soft, resilient, and more durable than regular cotton. The process results in fabric that is up to 30% stronger than regular cotton while being softer and more comfortable. The continuous twisting process produces longer, finer yarn, creating a softer, smoother, and more luxurious material that holds colors well and has anti-pilling properties.
Double-Needle Stitching Benefits
Double-needle stitching creates stronger, more durable seams that resist tearing and provide a professional finish. This construction method uses two parallel lines of stitching, which distributes stress more evenly across the seam and prevents single points of failure that can lead to garment damage during wear and washing.
"20 Single" Explained
Yarn Count (20)
The "20" indicates the yarn thickness using the cotton count system. In this system, the number represents how many 840-yard lengths of yarn weigh one pound. So 20-count yarn means there are 20 Ă— 840 = 16,800 yards of yarn in one pound. The lower the number, the thicker/coarser the yarn. Higher numbers mean finer/thinner yarn. 5s, 10s, 20s, and 30s are considered "large" or coarser yarns. 40s, 60s, 80s and up are considered "small/fine" yarns.
Single Construction (single)
The "single" means it's made from one strand (not plied). If it were "20/2" that would mean two 20-count strands twisted together.
Comparison
- 18 single = thicker/heavier (like Gildan 2000)
- 30 single = finer/lighter (premium lightweight tees)
- 40+ single = very fine (luxury/premium shirts)

I’ll keep this short and brief: • All the background and source material for Project Grindset shirts are available on the main website: https://www.substratum611.com/shopsubstratum611/project-grindset • (There are a lot of quotes so if it is easier, switch the view from “Gallery” to “Table” and you’ll be able to see everything in one place.) • Shipping times: The clothing and accessories you see here are primarily print on demand. Please allow 1-2 weeks for the items to be delivered. • Shrinkage: Shirts may shrink after a couple washes. Please keep this in mind before buying a size, as you may need to buy one size larger to get something that fits • Expected lifespan of clothing: Ideally 50-100 washes. DTF and DTG while cheaper and easier to print, aren’t as permanent as Sublimation printing
