What Sets our Toddler Union Suits Apart? 

Our toddler union suits offer the perfect blend of comfort and functionality. Here’s why it’s sure to become your toddler’s new favorite:

  • Handy zippers make it easy for little ones to dress themselves
  • Merino wool blends and innovative thermal fabrics help regulate your toddler’s temperature
  • Our toddler union suits are easy to care for—just machine wash on a low temperature using a gentle detergent and no fabric softener

Wool vs Synthetic: What’s the best Union Suit for your Toddler?

Our union suits and base layers come in different materials. High-performance synthetics like THERMOLITE® are quick-drying and retain their insulation properties even when they’re wet, making them perfect for activities like skiing. 

When it comes to warmth, however, wool is a winner—perfect for low-impact activities like hiking in cold weather. Because toddlers aren’t able to regulate their own body temperature as well as adults and older kids, our Merino wool blend union suits are perfect for toddlers. A mix of synthetic fibers and wool allows our toddler union suits to dry more quickly for a perfect blend of warmth and performance. It’s a win-win!
