Description
The UltraClub 8420L is the Women's Cool & Dry Sport Performance Interlock Tee, a 4.0 oz 100% micro-polyester interlock body with moisture-wicking, pill-resistant, UPF 30+ sun protection, and snag-resistant properties, built for women's athletic and uniform programmes that need a feminine-cut poly performance tee. It is the blank a shop reaches for when a programme needs a sublimation-ready women's body for full-colour all-over prints, a wicking tee for women's team and league uniforms, a sun-protective layer for outdoor staff and event crews, and any decorator who wants a women's poly interlock that handles sublimation, DTF, and screen printing at the lowest price point in the performance tee category.
As a 100% micro-polyester body, the 8420L follows the poly decoration rulebook with the advantage of a micro-denier face that gives a smoother, finer print surface than a standard poly knit. For sublimation, the 8420L takes full-colour dye-sublimation on White and light colours (Ice Blue, Sea Frost, Gray, Bright Yellow, Gold, Columbia Blue), with the dye bonding permanently into the micro-poly fibre for a no-hand full-bleed print. For DTF, the transfer bonds cleanly to the micro-poly interlock at standard heat-press settings across the full colour card including darks; DTF is the primary method when the base colour is too dark for sublimation. For screen printing, plastisol prints on the micro-poly face, but the standard poly dye-migration risk applies: lay a poly-blocking underbase on reds, oranges, and saturated darks, and cure at the lowest effective temperature. For embroidery, the 4 oz interlock supports a left-chest logo with a cut-away backing; keep the stitch count moderate on the lighter women's body. For vinyl and HTV, solid heat-transfer vinyl presses clean at a controlled temperature. DTG does not apply, since 100% polyester will not hold a water-based pretreat coat.

The reorder note specific to this style: the micro-poly interlock holds its colour locked in the fibre across wash cycles, so reorders are colour-consistent run to run. The UPF 30+ rating is a built-in feature of the fabric, not a topical coating, so it does not wash out. Pair the 8420L with the men's UltraClub 8420 and the youth UltraClub 8420Y for a matched women's, men's, and youth performance programme on the same Cool & Dry fabric. Cross-shop the Team 365 TT11W when a programme wants a similar women's poly performance tee, and the All Sport W1009 when the job wants a women's poly interlock with antimicrobial properties. TheClothingSpace stocks the 8420L at wholesale pricing with bulk discounts that increase as case and unit quantities rise, among the lowest prices online for this style, with fast US shipping on stocked colours.

Fabric Blend by Color Group
Not all colorways share the same fabric composition. Check the blend before ordering for decoration jobs where substrate matters.
| Color Group | Blend | Print Consideration |
|---|---|---|
| Light sport colours (White, Ice Blue, Sea Frost, Gray, Bright Yellow, Gold, Columbia Blue) | 100% micro-polyester interlock | Light colours are sublimation-ready for full-bleed all-over prints; the micro-denier face gives a smoother sublimation surface than standard poly |
| Mid-tone sport colours (Royal, Sapphire, Kelly, Jade, Heliconia, Purple, Cardinal, Orange, Bright Orange, Red) | 100% micro-polyester interlock | Mid-tone and saturated colours need DTF or screen with a poly-blocking underbase; reds and oranges carry the highest migration risk |
| Dark sport colours (Black, Navy, Charcoal, Indigo, Forest Green, Maroon) | 100% micro-polyester interlock | Dark grounds need full poly-blocking underbase for screen and DTF for the cleanest read; sublimation does not apply on dark bases |
