Bear Grips Pro ShopsCan You Sublimate a Gildan Crewneck Sweatshirt? What Actually Works
- Dye sublimation bonds permanently only to polyester fibers, not cotton.
- Gildan crewnecks are majority-cotton blends, so full sublimation prints will fade, ghost, or wash out over the cotton portion.
- A poly-heavy performance fleece is the right blank for true sublimation, not a cotton-blend crewneck.
- Bear Grips Pro Shops applies full-color designs directly to each crewneck with unlimited colors included, no separate sublimation step required.
Why Sublimation Ink Needs Polyester, Not Cotton
Dye sublimation works by turning solid ink into a gas under heat and pressure, which then bonds at a molecular level with polyester fibers as they cool. Cotton fibers do not have the same chemical structure and cannot accept that bond. Print a sublimation design on a 100% cotton or cotton-majority garment and the color sits on the surface instead of inside the fiber, then fades and cracks within a handful of washes.
What a Gildan Crewneck Sweatshirt Is Actually Made Of
Gildan runs several fleece lines at different cotton percentages, most commonly 50/50 cotton-poly blends and heavier all-cotton Ultra Cotton fleece. Even the poly-blend versions are majority cotton by weight, which means a full all-over sublimation print will look washed out, patchy, or ghosted wherever the cotton fibers dominate. A small sublimated patch heat-pressed onto a poly panel is a different story, but that requires a garment built with a poly panel in the first place, which a standard Gildan crewneck does not have.

Full-color, photo-realistic, all-over graphics need a poly-heavy performance fleece, not a cotton-blend crewneck. For a standard Gildan or Gildan-family crewneck, the print methods that hold up long-term are the ones built for cotton and cotton-blend fabric: direct-to-garment style full-color printing and screen-style spot-color printing, both of which bond to cotton fibers rather than requiring a polyester surface. Bear Grips Pro Shops applies designs directly to every piece in the catalog this way, with unlimited colors and design elements included in the base price and no per-color surcharge.
When Sublimation Actually Is the Right Call
- All-over, edge-to-edge photo-style graphics on a 100% polyester performance piece, not a cotton-blend crewneck.
- Jerseys and performance tees built from poly fabric are the correct substrate if the goal is a vivid, all-over sublimated look.
- A cotton-blend crewneck is the right call when the goal is a classic, structured, everyday sweatshirt with a clean logo or graphic rather than an all-over photo print.
Print the Right Way the First Time

Start FreeFrequently Asked Questions
Can I sublimate a design onto a Gildan crewneck sweatshirt?
Not reliably. Gildan crewnecks are majority cotton, and sublimation ink only bonds permanently to polyester. A sublimated print on cotton fades and cracks quickly.
What print method does Bear Grips Pro Shops use on crewnecks?
Designs are applied directly to the garment with unlimited colors and elements included in the base price, no separate sublimation step or per-color charge.
Is there a poly-heavy piece in the catalog for sublimation-style graphics?
The performance tees and moisture-wicking pieces run a higher polyester content than the cotton-blend crewnecks and hold vivid, full-color graphics better.
Will a sublimated logo eventually wash off a cotton sweatshirt?
Yes, typically within a handful of washes, since the ink sits on the surface of cotton fibers instead of bonding inside them.
