The list runs from a short-sleeve bodysuit to a team sweatshirt to a baseball cap, and which one fits depends on where the baby will be: a warm day at home, a cool night out, or a stroller photo.
1. Short-Sleeve Bodysuit
A short-sleeve bodysuit in team teal is the easiest Mariners piece to buy, and the one I’d pick first.
A short-sleeve bodysuit works as a layer under a sweatshirt or alone on a warm day, and a sleep sack over it keeps naps simple.
Snap closures at the bottom make diaper changes quick. Buy it a size up if the baby is close to the limit, because a bodysuit that rides up gets tossed fast.
2. Infant Team Sweatshirt
Stadium nights run cool, so a blue Mariners sweatshirt with the team logo does real work beyond looking cute. Put it over a plain bodysuit so you can peel it off when the stands warm up.
Loose sleeves and an easy neckline matter more than any print. For a game, pair the sweatshirt with baby ear protection, since a stadium crowd gets loud fast and infant ears are sensitive.
3. Infant Mariners Baseball Cap
Navy with a teal and white M is the cap that says Mariners at a glance. It’s the cheapest way to add team spirit to an outfit the baby already owns, even plain white.
Check for a soft, flexible brim and a snug fit. Babies pull caps off constantly, so I’d treat it as a photo and stroller piece rather than an all-day one, and keep a spare in the diaper bag.
