These heavyweight tees are a cornerstone of 3sixteen’s core collection and among the brand’s best-selling essentials for nearly a decade. Crafted from a custom-knit 260gsm jersey, the fabric is developed exclusively for 3sixteen by Roopa Knitting Mills—one of the world’s leading knitting mills.

The t-shirts feature a triple-needle coverstitched ‘never-sag’ collar and are fully cut and sewn in the same San Francisco factory that produces 3sixteen’s jeans, ensuring top-tier quality and consistency throughout the garment.

This latest version introduces several thoughtful upgrades:

• The fabric is now tubular knit (no side seams) for improved comfort and a cleaner silhouette.
• Each tee is pre-laundered, drastically reducing shrinkage and ensuring the fit stays true even after the first wash.
• The fit has been slightly updated to be roomier straight out of the box, offering a more relaxed and versatile silhouette.

Recognized by the Wall Street Journal in 2017 as the best t-shirt in the mid-price tier after evaluating over 50 styles, 3sixteen’s heavyweight tees continue to set the standard for quality and durability.

This pack includes two t-shirts.

Fit Notes: These tees stays true to standard sizing. If you usually wear a size M in 3sixteen shirts or other American brands, you'll find a suitable fit with this shirt in size M. However, as always, we recommend consulting our size chart for the perfect fit.
