Boys toddler long sets bring together a long-sleeve top and matching long pants, so you get a coordinated outfit without hunting for pieces that go together. They're built for the busy years between 2 and 4, when a toddler is climbing, running, and changing his mind about everything. If you want everyday outfits that look pulled together with zero effort, this collection is an easy place to start, and you'll find plenty more to pair it with in our toddler collection.

Toddlers grow in unpredictable spurts, so lean on his current measurements rather than his age when picking a size. Our sizes by age guide and the size converter can help you match up numbers, and our fabric comparison is worth a read if feel and stretch matter to you.

  • Measure his height and chest, then compare against the size chart before ordering.
  • Look for pants with an adjustable or elastic waist to keep up with growth.
  • Choose looser fits if he's between sizes so there's room to move and layer.

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.
