New York Mets Newborn & Infant Alternate Replica Romper Jersey - Royal

The stands are loudest when the whole crowd is dressed as one. Slip into this New York Mets jersey and you're not just attending the game — you're part of it.

Product Overview & Specifications+
This is a fan-version jersey — cut for comfort, priced for real fans, and made to survive everything from stadium seats to backyard watch parties.

Comfort That Lasts All Matchday

Quick-drying weave made for long matchdays — comfortable from the tailgate to the final whistle.

A Fit for Real Fans

Made for little ones who can't cheer yet but already look the part — comfy, breathable, and machine washable.

Style That Reads from the Parking Lot

Modern, streamlined, and unmistakably New York Mets — it reads from across the parking lot.

Built to Hold Up

Printed details are finished to survive the washing machine, not just the product photo.

This Season’s Look

This this season version keeps the look current while staying true to what fans love about New York Mets.

Product Highlights & Craftsmanship+

Pairs as easily with jeans and sneakers as it does with face paint and flags. Game night, gym session, or a casual Friday at work — it fits the day, whatever the day brings.

Surprise a fellow supporter with their team's colors — add their name and it becomes a keepsake.

Shop with Confidence+
  • Style: replica fan jersey with the alternate look of New York Mets.
  • Fit: infant sizing; check the size chart for exact chest measurements.

True to size for most fans; if you prefer a looser, game-day layering fit, consider going one size up.

Frequently Asked Questions+

Every size option is listed on the product page, so you can pick with confidence before checkout. What you see is what you get — clear photos, honest sizing, and a fan version described exactly as it is.

Keep it fresh: machine wash cold, inside out, and skip the iron on printed areas.

Does this fit like the batting practice jerseys?+
It's a fan version with a relaxed, comfortable cut — inspired by the on-field look but made for everyday wear.
Is the color exactly as shown?+
We photograph every piece in natural light to keep colors true. Slight differences between screens are normal.
Can I wear this for everyday outfits?+
That's exactly what it's for. It layers over a tee or under a hoodie and works with jeans, joggers, or shorts — game day and any other day.

Add it to your cart and wear your colors with pride this season.
