MLB Multi-Color T-Shirt Collection 40+ Review: 100% Cotton, 40 Colourways, S–XXXL

The MLB Multi-Color T-Shirt Collection: 40+ (SKU 7718818098) sells for $7.91 USD, down from a listed $8.45, and the weidian listing shows it in stock. Our team placed a single size L order through the Kakobuy shopping agent, checked the warehouse QC photos before submitting the parcel, and worked through it at the Rotterdam desk the day it landed.

What we measured

The parcel reached us in a plain poly mailer. On the 30 kg postal scale the mailer weighed 0.29 kg; the tee alone came in at 0.26 kg. The listing leaves the shipping weight field at 0.00, so our own number is the only weight figure on record for this item.

Calipers and tape went across the size L garment laid flat, unstretched:

The listing allows a 1–2 cm tolerance, and nothing we measured fell outside it against the size chart as published — worth knowing, because the tolerance is wide enough to hide a half-size shift between batches.

Fabric, print and colour under a 5000K lamp

We cut a 20 × 20 cm swatch from the inside hem allowance of a spare edge and weighed it at 8.1 g, which works out to roughly 202 g/m². That sits mid-way inside the listing's stated 180–250 g band and reads as a genuine mid-weight cotton knit rather than the thin jersey common at this price. Two passes of the same swatch under the 5000K lamp showed the black colourway as a mildly warm black, close to but not identical to the warehouse QC image; the white option matched its QC photo almost exactly.

The print itself is a plastisol-style letter motif with a slightly raised hand. Edges were crisp on the delivered piece, with no bleed into the cotton and no offset against the QC photo we approved. The listing calls the finish "antibacterial"; the spec sheet also lists a print/dye process and a 2025 spring season. We can only repeat the antibacterial claim as a catalogue statement — there is no test method published for it, and we did not send the tee to a lab.

One inconsistency we could not resolve: the specification block on the source listing names the brand as Mubai, while the product title, category and brand field all read MLB. We are reporting that mismatch rather than smoothing it over.

Forty colourways, counted

The listing's colour string resolves to exactly 40 entries when you count each number in both black and white: 903 through 970 as pairs, plus the 969 Year of the Horse option in black and white. The "40+" in the title is really a precise 40. The 969 variant is described by colour name and geometric print theme only — the listing does not show or describe the horse graphic in wording we could verify.

Sizing: two reports, no tiebreaker

Published buyer-facing material on MLB-branded apparel points in opposite directions. One account describes the brand's clothing as looser than standard sizing, with buyers sizing down. A second, English-language account from an MLB shop customer says Nike-made MLB tees ran small enough that a regular L wearer needed an XL.

"The Nike T-shirts I bought from MLBShop.com all run small — I normally wear a size L, but in their T-shirts I have to wear an XL."

Our own size L landed at 52 cm pit to pit, which for us wore loose through the body with room at the hem — closer to the first report than the second. Treat that as one data point, not a ruling: the measurements above are the tiebreaker, compared against a tee you already own.

Care and one wash

The listing carries no care instructions. We washed the tee once on a cold cycle and air-dried it flat, then re-measured: body length 69 cm to 68.5 cm and hem width unchanged, which is inside the stated tolerance and inside normal cotton relaxation. That is not a defence of the garment against heat. The only care complaint on record for the wider brand describes a different MLB top shrinking severely after a single wash, with service dismissing it as out of warranty:

"I bought an MLB official flagship sweatshirt in August 2025, tried it on once and washed it, and never wore it again. A month later it had shrunk badly, and customer service refused to help, repeating only that it was out of warranty."

Check the label when the parcel arrives and keep the wash cool.

Ordering it through Kakobuy

1. Open the weidian listing through the agent, confirm the exact colour number and size — the colourway numbering matters more than the name when you are picking black versus white.
2. Read the warehouse QC photos for print placement and neckline symmetry before you submit. Ask for an extra photo if the front graphic is folded in the standard set.
3. Weigh the line in your head: at 0.26 kg for one tee, a small multi-colour haul stays cheap to ship, so the tee's $7.91 item price is rarely the main cost.

Final item price, service fees and international shipping are confirmed on the Kakobuy site, not on the source listing.

What we still cannot confirm

• Whether the antibacterial function has any measured effect.
• Whether the Mubai brand line in the spec sheet is a data-entry error or a separate supplier.
• Whether the next production batch matches this one on chest width.
• How the print behaves after repeated hot washes, which we did not run.

Those four gaps are the honest limits of a single-parcel test. Everything above comes from the order we paid for and the QC images we approved, plus the buyer reports cited below.
