UltraClub 8420 Red Cool & Dry Performance Blank

Description

The UltraClub 8420 is a 4 oz 100% polyester interlock performance tee with moisture-wicking, UPF 30+ UV protection, and pill-resistant and snag-resistant finishes. The pill-resistant and snag-resistant treatments set the 8420 apart from standard polyester performance tees in the wholesale channel: the fabric holds its smooth surface through repeated washing and physical contact, which matters for athletic teams, outdoor staff, and corporate programs where the garment sees heavy use. The UPF 30+ rating blocks over 96% of UV radiation. Sizes run from S to 6XL, which covers the extended size range that many competing performance tees cap at 3XL or 4XL.

The 100% polyester substrate opens the full range of poly-compatible decoration methods. For sublimation, the 8420 takes full-colour sublimation on white and light-coloured garments with vibrant, permanent results, since the dye bonds directly into the polyester fibre. The pill-resistant finish does not interfere with sublimation bonding. Route dark bodies to DTF or screen printing. For DTF transfers, the polyester surface bonds well with transfer adhesives at standard press settings across the full colour card. For screen printing, plastisol prints on the poly face. The 100% polyester carries the highest dye migration risk. Use a poly-blocking underbase and cure at the minimum effective temperature on all coloured garments without exception. For embroidery, the 4 oz interlock handles left-chest logos with a cut-away backing. For vinyl/HTV, the polyester surface holds vinyl at standard settings.

Frequently Asked Questions

What is the fabric composition of the UltraClub 8420?

The UltraClub 8420 is 4 oz/yd2 of 100% polyester interlock with moisture-wicking, UPF 30+ UV protection, and pill-resistant and snag-resistant finishes. The pill-resistant treatment keeps the fabric smooth through repeated washing and physical contact, which standard polyester performance tees lack.

Can the UltraClub 8420 be sublimation printed?

Yes. The 8420's 100% polyester substrate takes full-colour sublimation on white and light-coloured garments with vibrant, permanent results. The pill-resistant finish does not interfere with sublimation dye bonding into the polyester fibre. Route dark and saturated colours to DTF or screen printing.

What sizes are available for the UltraClub 8420?

The UltraClub 8420 runs from S to 6XL, which is a wider size range than most competing performance tees that cap at 3XL or 4XL. The extended sizing to 5XL and 6XL makes the 8420 the default for programs that need to cover a full roster or staff without switching styles at the upper end.

How does the UltraClub 8420 compare to the Team 365 TT11?

Both are 100% polyester performance tees with moisture-wicking. The 8420 at 4 oz adds pill-resistant and snag-resistant finishes with UPF 30+ and runs to 6XL. The TT11 at 3.8 oz has UPF 40+ (higher UV rating) and cationic dyes for brighter colour. The 8420 wins on durability and extended sizing. The TT11 wins on UV protection and colour brightness.
