Meet the ONERUN HEAVY T-SHIRT 2 — a unisex heavyweight long-sleeve tee built for real-world wear, screen printing readiness, and responsible production. At its core is a tightly woven, durable fabric that doesn’t quit, making it the versatile choice for teams, workwear, and everyday layering.

Why this tee stands apart

• Six-ounce, 20-singles fabric delivers substantial durability while maintaining a smooth surface ideal for high-clarity prints and logos. The heft means it resists wrinkles and holds its shape through daily wear and washing.
• Premium fiber blend options:
  • Standard: 100% Airlume combed and ringspun cotton for a soft, premium feel.
  • Athletic Heather: 90% Airlume cotton / 10% polyester for a little extra drape and resilience on heather tones.
• Construction designed for comfort and longevity — drop shoulder for a relaxed, easy fit; side-seamed to maintain shape and resist twisting; pre-shrunk to minimize surprises after laundry day; tear-away label for itch-free wear.
• Boxier, relaxed fit provides room through the chest and torso without looking oversized, making it a dependable base layer or standalone tee.
• Sustainable by design — WRAP Certified and FLA participating, with Blue Sign certified dyes. The dye houses adhere to California EPA wastewater regulations, and Los Angeles cutting facilities run on partial solar power with recycling programs for paper waste and fabric scraps.

Fabric details that matter

This tee isn’t just thick; it’s thoughtfully built. The 6 oz weight strikes a balance between warmth and breathability, so it’s comfortable in a range of environments—from chilly warehouses to casual outdoor days. The combination of Airlume combed and ringspun cotton ensures a smooth hand feel and improved print definition, so your logos pop with crisp edges and vibrant color.

Who should wear it

• Teams and clubs needing durable, consistent apparel that prints cleanly on every jersey or training shirt.
