The Kirkland Signature Men's Heavyweight Crew Neck T-Shirt 6-Pack delivers exceptional everyday value with six premium cotton tees in a single purchase. Each shirt is crafted from 100% combed ringspun cotton using a tubeknit construction, resulting in a fabric density of approximately 205 GSM — placing it firmly in the heavyweight category and making it one of the densest shirts in its price range.

The tagless design eliminates neck irritation, while reinforced seams add long-term durability. Individual shirts weigh approximately 231 grams out of the box, and independent testing has confirmed the fabric is thick enough to pass opacity tests with ease. These shirts are known to hold up extremely well over time and through repeated washing.

The fit is relaxed and generously cut, designed for comfort rather than a slim silhouette. The shirts run approximately one size large, so sizing down is recommended. Available in a range of sizes from Small through 3X-Large. Expect approximately 5% shrinkage after the first wash. Backed by Costco's satisfaction guarantee.
