When evaluating CVC (Chief Value Cotton) Single Jersey, you must prioritize the blend ratio, typically 60% cotton and 40% polyester, which ensures a balance of breathability and durability. Pay close attention to the GSM (Grams per Square Meter); for standard T-shirts, a range of 140-180 GSM is ideal, while lightweight summer wear may require 120-130 GSM. Additionally, verify the yarn count (e.g., 26s, 30s, or 40s)—higher numbers indicate a finer, smoother fabric surface suitable for high-end apparel.
