Discover the comfort and quality of the City Threads Union Suit Thermal Underwear, designed for both boys and girls. Made in the USA, this thermal underwear is a blend of soft cotton and polyester, offering a perfect mix of warmth and breathability.

Parents have noted the exceptional softness of the fabric, which is ideal for children with sensory sensitivities. The lightweight material ensures that it doesn't overheat, making it suitable for all seasons. However, some users mentioned that the fabric tends to pill after a few washes, which might be a concern for those with sensory issues.

Size can be tricky with this product. Several reviews suggest ordering one or two sizes up as the suits tend to run small. Despite this, the quality of stitching and durability are highly praised, with many expecting to pass them down to younger siblings.

The design features practical buttons that are easy for children to manage independently, enhancing their self-reliance. Although some parents reported issues with buttons coming undone during sleep, others found them secure enough for all-day wear.

Overall, the City Threads Union Suit is celebrated for its comfort, quality construction, and stylish appearance. While there's room for improvement in fabric choice and sizing accuracy, it remains a popular choice among parents looking for reliable thermal wear for their kids.
