The listing for this MLB tee promises a lot of breadth and very little depth. SKU 7718820120 is priced at $3.73, down from $4.37, marked in stock, and available in 39 print or plain variants across sizes M to 5XL. What the listing does not publish is a full numeric size chart, a piece weight, or any buyer history for this exact SKU. So our testing team built the baseline itself: the same XL variant was ordered three times, roughly a month apart, and each parcel was measured flat on the mat in the Rotterdam room before anything went near a wash.
What the listing actually commits to
The published specification is short and mostly qualitative. Brand MLB, category T-shirts, 2024 summer release, polyester as the main fibre under the trade name milk silk, an ordinary thickness quoted at 180 g to 250 g, breathable as a stated material function, short regular sleeves, a round neck, pullover construction and a loose cut. The only numeric precision on offer is a 1–3 cm stated measurement tolerance. Everything else — including whether the print survives a summer — is left to the parcel.
That is the gap three orders were designed to close. If the cut and the print are stable from batch to batch, the low price stops being a gamble and becomes a replaceable shirt. If they are not stable, the same low price is a lottery ticket.
Three parcels, one month apart, measured flat
All three orders were the same XL, short-sleeve, white base with the large blue back graphic. Measurements were taken flat, seam to seam, on the same mat with the same tape, after each shirt had rested overnight out of the bag.
| Order | Placed | Flat chest (pit to pit) | Body length | Print width | Piece weight |
|---|---|---|---|---|---|
| 1 | Week 1 | 55.0 cm | 70.5 cm | 25.8 cm | 185 g |
| 2 | Week 5 | 55.8 cm | 71.0 cm | 26.1 cm | 187 g |
| 3 | Week 9 | 56.6 cm | 71.5 cm | 25.6 cm | 191 g |
The spread is small in every column. Chest moved 1.6 cm across two months, body length 1.0 cm and the back print width 0.5 cm — all inside the 1–3 cm tolerance the listing states. For a shirt bought in three separate orders through the same agent pipeline, that is a steadier result than the price suggests, and it is the single most useful thing we learned about this listing.
What the numbers say about the cut
A 55–56.6 cm flat chest on a relaxed XL is a genuinely loose body, consistent with the listed silhouette rather than a slim substitute. The hem sat level on all three units and the shoulder seam landed in the same place, so the block itself is not drifting even if the tolerance allows it to. Because the listing publishes no chart, the honest way to use these figures is as a comparison against a tee you already own measured flat — not as proof that XL will fit your usual XL.
Batch drift on the back print
The graphic is the whole point of this variant: an interlocking NY mark with stars and thorn-like details, printed large across the back with lettering underneath. We checked each parcel on the lightbox before consolidating and compared the three prints side by side after the third arrived.
- Registration between the logo edge and the star and thorn elements was consistent across all three units.
- The blue ink read as the same blue on every parcel; no unit arrived noticeably lighter or greener than the others.
- Print width varied by 0.5 cm and print height stayed within roughly a centimetre, which is normal for a screen-printed panel.
- The lettering below the motif kept its spacing and baseline on all three, with no squeezed or clipped letterforms.
What this does not answer is durability. Three clean, unworn prints say nothing about cracking, flaking or fading after twenty wears, and there is no buyer record on this SKU to fall back on. Community discussion of MLB-branded tees is explicitly negative on exactly that point: buyers describe the shirts as very thin and the printing as cheap and low quality. That complaint is a category pattern rather than a finding about this garment, but it names the part of the shirt most likely to disappoint, and it is why the print is what our team will re-check on the six-month retest.
“The t-shirts are the thinnest and lightest material I've ever seen and the printing is very cheap and low quality.” — buyer complaint in r/mlb, quoted as category context, not as a test result for this SKU.
Weight, thickness and the milk-silk wording
Weighed out of the bag and with the polybag subtracted, the three pieces came in at 185 g, 187 g and 191 g. A loose XL tee uses roughly a square metre of fabric, so those figures put the cloth near the lower end of the 180–250 g band the listing quotes — technically inside the claim, practically the light half of it. The Milk Silk name is a trade description for a fine polyester filament, not a blended fibre, and the breathable note is a stated material function rather than a measured airflow number.
This is where the price becomes visible. A polyester tee at this weight is not built to feel substantial; it is built to be light, quick to dry and cheap to replace. Buyers in a community thread on fabric choice make the useful comparison directly: cotton absorbs sweat and feels comfortable but can shrink, while polyester blends avoid shrinkage and hold their shape — and cotton shoppers often size up because of it. That shrinkage argument does not transfer here, because there is no cotton in this garment to shrink. The shape-holding half of that reasoning does apply, and it is consistent with a shirt that measured the same three months running.
Stitching, collar and arrival check
Construction was ordinary rather than impressive, and consistent across all three parcels: overlocked side and sleeve seams, a double-stitched hem, and a ribbed crew collar that sat flat on arrival with only light folding creases from transit. Our arrival log recorded the odour as a mild new-garment smell on all three, gone after a day aired; no loose threads, no open stitch runs and no hardware to check on a pullover tee. We washed one unit once and it came out without measurable change to the chest or length.
For readers who want a checklist that travels beyond this one order, MLB-focused authentication guidance is worth applying: the fabric should feel soft yet durable, with no loose threads or irregular stitching, and the print should show consistent colour and pattern alignment across the graphic. Our three units passed all of those on delivery. The unanswered question is how they look after a season of washing.
The value case, and its limits
At $3.73 this shirt costs less than the shipping line that carries it. That changes what a fair judgement looks like. Judged as a garment, it is a light polyester tee with a bold back print, an ordinary finish and no size chart. Judged as what it actually is — a cheap, repeatable streetwear layer in a very wide variant range, with measurement consistency we could verify across three separate batches — it performs better than its price implies, and better than the worst category complaints about MLB-branded printing would lead you to expect.
Three things stay open after our testing. Print durability over a full summer is unverified. There is still no buyer record for this exact SKU, so our three parcels are the only evidence on the table. And without a published numeric chart, fit remains a measure-it-yourself exercise rather than a listed guarantee.
