How should I choose the right size for Rocky Thermal Underwear for my child?

Rocky Sets Editorial Review
The Rocky Thermal Underwear for Boys Cotton Knit Thermals Kids Base Layer Long John Pajamas Set promises to provide warmth and comfort during cold weather. However, customer experiences with this product have been mixed. One major issue that customers have raised is the discrepancy in the fabric composition. Despite the product description stating that it is 100% cotton, it is actually made of a blend that is 55% cotton and 45% something else. This has left some customers disappointed, especially those who specifically wanted 100% cotton. Another concern is the quality of the Construction. Several customers reported that the pants started falling apart after only one wear, with the threading coming undone. Additionally, some customers noticed loose threads upon receiving the product, suggesting a lack of attention to detail in the manufacturing process. On the positive side, customers did appreciate the softness of the material, even after washing. They also found the thermal underwear to be effective in keeping their children warm. The flexibility of the fabric allowed for ease of movement, making it suitable for both layering and as pajamas. In terms of sizing, there seems to be some confusion. The provided size chart on the package differs from the one shown online, causing uncertainty for customers trying to choose the correct size. Some customers found that the thermal underwear fit as expected, while others felt that it ran either too small or too large. Despite some positive feedback on comfort and warmth, the overall customer experience with the Rocky Thermal Underwear for Boys Cotton Knit Thermals Kids Base Layer Long John Pajamas Set has been marred by issues with fabric composition, Construction quality, and sizing inConsistencies.
