Hi Sarah,

Thank you for reviewing our Kids' Ski Base Layer Top - BL 500 Black.

We're glad that you found the right first layer for your kids to stay warm this winter!

We hope to see you again soon,

So good!

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.

Hi Jerome,

We are so glad to hear, thank you for sharing your experience with us.

Very warm

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.

The thermal is good but if your are wearing for kids kindly check because there may be treads handing out and it may cause uncomfortable for the kids.

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.
