Let me start by saying, these Rocky Thermal Underwear sets are a game-changer for parents battling chilly weather. I bought these for my 7-year-old son, and the first thing he said when he tried them on was, 'Mom, these feel like a warm hug!' That pretty much sums up the comfort level.

The fleece-lined interior is incredibly soft – no itchiness at all. My son wears them under his hockey gear, and even after hours on the ice, he stays toasty without getting sweaty. The moisture-wicking fabric really works as advertised.

I was pleasantly surprised by the durability. After multiple washes (we're talking weekly hockey practices plus weekend skiing trips), there's no fading or significant pilling. The stitching has held up perfectly against rough play and frequent laundering.

The sizing runs slightly large – we ordered his usual size Small (he's about 50 inches tall), and there's plenty of room to grow. This actually worked in our favor since we've gotten two winters of use from one set!

My only minor complaint? The waistband could be a bit snugger for very active kids. During intense hockey games, we sometimes need to tuck the shirt into the pants to keep everything in place.

At this price point, you simply can't beat the value. We've tried more expensive brands that didn't perform nearly as well. These thermals have become our go-to for winter sports, school days when the temperature drops, and even as cozy pajamas on extra cold nights.

Pro tip: If your child is between sizes or you want a snugger fit for sports, consider sizing down. Otherwise, stick with their normal size for comfortable layering under everyday clothes.
