City Threads Union Suit Thermal Underwear is a high-quality, made-in-USA product designed for kids who need warmth and comfort. The blend of cotton and polyester ensures a soft, breathable fabric that’s perfect for sensitive skin. However, sizing can be tricky—many parents recommend going up one or two sizes to avoid issues like wedgies or short sleeves.

The fabric is lightweight yet surprisingly warm, making it ideal for both lounging and layering. Kids love the softness, and parents appreciate the durability. However, some users noted that the fabric tends to pill after a few washes, which could be a concern for sensory-sensitive children.

Pros include excellent stitching, easy-to-use buttons, and stain resistance. The fact that it’s made in the USA adds to its appeal for those prioritizing ethical manufacturing. On the downside, the cotton/polyester blend isn’t everyone’s favorite, especially for sleepwear.

Overall, this union suit is a solid choice for parents seeking cozy, well-made thermal wear for their kids. Just keep in mind the sizing quirks and fabric blend when making your purchase.
