Review: Excellent quality, soft warm and great for under regular clothes. - Editing my review just to say we now by these for our boys every year. We love soft warm thermals in this family and have tried many many brands, for our young boys this is our choice. These are amazing, we even wound up using them as pajamas often. Very soft and warm but thin enough to be worn under jeans and other shirts or sweaters. I made sure every family member had more than enough warm clothes to get through the winter and got these for my 6 year old, they are amazing. I plan on getting these for both my son's now and will most likely repurchase in other sizes as they grow.
Review: Warm and comfortable - Great product! It’s warm and comfortable. Size is great.
