ZOEREA hooded set means less stress in the morning when it's cold. You only need to grab one hanger and you're good to go. The sweatshirt is a comfortable cotton blend with printed lettering and the hood has a fun flower patch to give a bit of personality. The pants match and go on easily with the elastic waistband so you don't have to deal with buttons while toddler is wiggly. It's soft and breathable on the skin which is great as you begin to layer more as October hits. They have sizes from 12-18 months to 5T, so there's room to grow. Just keep in mind that this is a lightweight/medium weight set and is better for layering in the fall than it is as a single piece through the winter. Great gift or wardrobe staple.
