Description
The District DM138L is a 4.5 oz women's Perfect Tri racerback tank constructed from 50/25/25 polyester/combed ring-spun cotton/rayon at 32 singles. The tri-blend jersey produces a heathered appearance and a soft, drapey hand that standard 100% cotton or 50/50 tanks do not match. The racerback cut allows full range of shoulder motion and is the standard silhouette for fitness, yoga, and active event merchandise programs.
The 50% polyester in the tri-blend creates dye migration risk that determines the decoration strategy. DTF transfers are the most practical method because the film bonds to the blended face and blocks migration. Screen printing with plastisol needs a poly-blocking underbase and low cure on all colourways. DTG is possible but the 50% polyester mutes vibrancy. Discharge is not viable on a 50% polyester blend. The tri-blend fabric is heat-sensitive, so press time and temperature must be controlled during any heat-applied decoration. 1x1 rib knit neck and armholes, back neck tape, curved hem, and tear-away label complete the construction.

Decoration Method Compatibility
How this blank performs across popular decoration methods.
| Method | Compatible | Notes |
|---|---|---|
| DTF Transfer | ✓ | Most practical for tri-blend. Film bonds to blended face. Blocks migration from 50% polyester. Control press temperature. |
| Screen Print (Plastisol) | ✓ | 50% polyester needs poly-blocking underbase and low cure. Heat-sensitive fabric requires careful cure control. |
| DTG | ✓ | 50% polyester mutes vibrancy. Vintage-look output. DTF more reliable on this tri-blend. |
| Embroidery | ✓ | 4.5 oz body is moderate weight. Keep stitch counts low on racerback panels. Cut-away stabilizer. Left-chest only. |
| Vinyl / HTV | ✓ | Polyester-safe temperature. Heat-sensitive tri-blend requires lower temp and shorter press. Small logos. |
| Sublimation | ✗ | Only 50% polyester with cotton and rayon. Cotton and rayon prevent clean sublimation. Not suitable. |
| Discharge Printing | ✗ | 50% polyester prevents discharge. Not viable on this tri-blend. |

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 |
|---|---|---|
| All tri-blend colourways | 50/25/25 polyester/combed ring-spun cotton/rayon, 4.5 oz, 32 singles | Poly-block underbase and low cure on all. DTF most practical. DTG muted by 50% poly. Heat-sensitive fabric. |
| Lighter heathers | 50/25/25 poly/cotton/rayon, 4.5 oz | Lighter grounds show art with less underbase density. Same poly-block precautions. Heather texture visible through lighter deposits. |
