Review: I would give 10 stars if I could! I will be ordering more for my little guy. It was a struggle to get him to even let me wash them. He has issues with textures but these were perfect for him in every way. I ordered them for a trip to the mountains, thankfully they arrived 5 mins before we left (my fault for last min ordering). They are not thick and have a thin lining of fleece but they are smooth, soft and kept him very warm and comfortable on our hikes in the cold mountains. He wore them the entire trip barely letting me wash them. They wash well, no shrinking nor fading of the vibrant blue. This is definitely worth every penny. Thank you from me and my little one!

## Questions & Answers

**Q: I saw a review that stated these are not fleece lined but product description shows it.. can anyone confirm the fleece lining in this product?**
A: The ones I recieved have a very thin fleece lining it's not what you imagine when you hear fleece. But I have several different brands that are fleece lined and they all are made the same. They are made to go under clothing and not be bulky.

**Q: Can the small size fit 2 year old**
A: Too big for a two year old.

**Q: Where can I find sizing chart? What are the ages/measurements of the garments?**
A: At the bottom/ small, medium, large

**Q: How do you tell what the size range is for small?**
A: By sizing my son to my grand son they are one size off from each other
