About the Gildan G420
The Gildan G420 Performance Tee is a 5-ounce 100% polyester blank built for active programs that need real moisture management at a wholesale price. The 100% spun polyester construction delivers moisture-management, odor control, and snag resistance — and unlike a lot of pure-polyester performance fabrics, the G420 has a soft hand of cotton that keeps it comfortable for everyday wear. For school athletic programs, summer camps, outdoor staff, and any program where the shirt gets worn during physical activity, those features matter every day.
The modern classic fit sits a bit closer to the body than a traditional unisex tee but isn't compression-tight, which strikes a useful middle ground for athletic and team applications. Side seams give the body a cleaner shape than a tubular construction, and taped neck and shoulders add durability where the seams take the most stress. The 100% polyester construction makes the G420 the ideal choice for sublimation printing, opening up vibrant all-over color decoration for programs that want full-coverage prints rather than standard chest or back placement.
The Safety Green colorway is compliant with ANSI/ISEA 107 high-visibility standards, making the G420 a practical choice for workwear programs that require certified high-visibility apparel rather than just bright tones. The shirt is also made in an OEKO-TEX and FLA certified facility, which matters for buyers who track responsible sourcing across their wholesale orders.
For a comparable performance tee from another brand, the Sport-Tek ST350 PosiCharge Competitor Tee is the most widely ordered alternative. For an athletic blank with sun protection, the A4 N3142 Cooling Performance Short Sleeve T-Shirt adds a UPF 30+ rating to the moisture-wicking feature set. For a softer triblend performance option, the Sport-Tek ST410 PosiCharge Tri-Blend Wicking Draft Tee covers the lifestyle-adjacent end of the performance category.
FAQ
Is the G420 good for sublimation printing?
Yes. The 100% polyester construction is the ideal substrate for sublimation, which requires high polyester content for vibrant, durable color transfer. The G420 is one of the more accessible sublimation blanks in the wholesale market for programs that want all-over color decoration on a budget-friendly performance tee.
Can I screen print on the G420?
Yes, but with the polyester-specific techniques most decorators already know. The 100% polyester construction can cause dye migration with standard plastisol inks at high cure temperatures, so polyester-friendly inks (low-bleed plastisol or low-cure water-based) and a barrier underbase on dark colors are usually required. For the best print quality without those workarounds, sublimation or DTF heat transfer is the simpler path.
What does ANSI/ISEA 107 compliance mean?
ANSI/ISEA 107 is the American National Standard for high-visibility safety apparel. The Safety Green colorway of the G420 meets the standard for high-visibility background color, which means it satisfies specific requirements for color saturation and visibility under various lighting conditions. For workwear and safety programs that require certified high-visibility apparel, the G420 in Safety Green is a practical option — though for full ANSI/ISEA 107 garment-level compliance with reflective striping, you'll want a Class 2 or Class 3 vest layered over the tee.
