Color, fabric condition, design are all good. It's warm and soft, so even kids love it. It is better to choose a generous size. It's stretchy, so I think the regular size would be fine.
Great buy
Hi Jerome,
We are so glad to hear, thank you for sharing your experience with us.

This garment is very soft and warm. This is made of a long mesh material in the middle of the back, so it's okay to sweat. My child likes it very much. The color of this Tee is also very lovely.
Hello Jieun,
Thank you again for your feedback.

Great value, well worth the money, my boy loved it, brought the bottoms 2
Comfortable material and was warm enough for kids skiing. Recommend to go one size up if between age as it ran a tad short
好透氣
Nice product
Excellent inner layer and would have loved to havr a lower in a set as well. My child was warm and comfortable in it
Value for money
Awesome Product. Works so much better in low temperatures. Because of its pattern design, we can use this as normal sweatshirt in moderate cold zones.

Additional Product Information
Composition
Main fabric: 91.0% Polyester, 9.0% Elastane ; Yoke: 88.0% Polyester, 12.0% Elastane
What is the fit of the bl 500 ski base layer?
The BL SKI 500 JR thermal ski base layer has a standard straight cut that adapts to all body shapes.Not too loose so it’s efficient and keeps in the heat.
What are the benefits of polyester?
Polyester is the most-used fibre for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibres can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet.
How to dress to stay warm on the slopes?
You just need 3 technical layers to keep warm on the ski slopes:- Layer 1 or a second skin, to stay dry.- Layer 2 or an insulating layer, to keep the heat in. - Layer 3 or a protective layer to protect against the elements.
