Mountain WarehouseMerino Kids Round Neck Thermal Baselayer Top – Long Sleeve, Lightweight, Antibacterial, Breathable & Quick Dry T-Shirt - Travelling & Outdoors

Though it's for child, I bought this for myself. This thermal is just incredibly warm, I'm naturally a cold person and wearing this just keeps me warm the whole winter!Make sure to get the right size though, definitely need to be snug. For me, I'm 155cm and size 9-10 years old fits better than 11-12 years old, as the material is stretchy.My only complain is that the neckline is not scoop so it shows up in most of my tops, but then it's a kids clothing so I suppose it has to be a round neckline instead of scoop.

Brought for my little girl to wear on her horse riding lessons. Lovely material and comfortable to wear! This sizing is accurate and Also the colour is lovely!

These might be slightly more expensive but the quality of this item is apparent and definitely worth it. Exceptional quality and super soft. I have a child who had sensory issues and loves these, no seams and no labels. They aren't see through. Fit can run slightly bigger, no need to size up. I just bought my daughters usual size. My daughter likes to wear these as an outfit as well for going out.

Bought this for my son to go with the matching under trousers. Very good price for Merino (mix) and my little lad loves them

Very warm. Son tries to wear it everyday but could have used a size or 2 smaller than the age required. Easy to care for. Essential for the winter.

My kid love it. It is warm but don't let him get very hot.Very good purchase.

I assumed that size 11-12 would fit my tall 10 year old, for whom I buy clothes size 11. This is huge. At least 2" too long on the arm. (Other size is 9-10 so it was, what I thought, a fairly obvious decision.) So, double check the measurements of your child (although only waist and chest sizes are given) and assume this is large. I also expected a snug fit. As a base layer I'm not sure what you'd put anything over it; her running or football kit wouldn't fit. I didn't expect it to be so fine either - you can see through it. But perhaps it would keep a larger kid warm. Anyway, decision is yours of course but this one's going back.

Really nice base layer

Great quality which was expected

My boy loves it as it is soft and warm

Second of these I've purchased. Great quality and keeps kids warm. Excellent value for the price.

Fits my nine year old granddaughter great. She says it’s soft and keeps her warm when snowboarding.

They are very comfortable and they feel great, the kids wont take them off. I will have to see about quality though, after just 2 days there are serious signs of wear and tear around elbows.
