Boys baby long sets pair a long-sleeve top with matching pants, made for the 3-24 month stretch when the weather turns cool and babies are busy rolling, crawling, and pulling up. These two-piece sets are handy for everyday wear, layering under a jacket, or dressing up a little for family photos, and the mix-and-match nature means you can swap pieces as they get worn or outgrown. If you're building out a cool-weather wardrobe, browse the wider baby collection for more options.

To pick the right size, go by your baby's current weight and height rather than age alone, since babies grow at their own pace. Our sizes by age guide and the size converter can help you match measurements to a size. For a longer season of wear, consider the next size up if your little one is between sizes.

  • Look for wide or snap necklines that make quick head-first dressing easier.
  • Roomy pant legs and covered feet suit babies who are always on the move.
  • Curious about how different fabrics wear and feel? See our fabrics compared guide.

Not sure which size? Use the baby clothes sizes-by-age guide or the size converter — sizes run different by brand, so see why before you buy.
