Product Customer Reviews

Hi, This item is awesome, just one adjustment a waist cord for skinnier kids. Thank you.
Good quality
Warm base layer for kids, size is smaller than expected, with legs quite short even with my average height child.
My child refused to wear a jacket on top of his costume so this served its purpose! And it is not only for skiing. Just a really good buy!
Bought to keep kids warm while doing outside sport and they havent complained about being cold! Wash really well too and great value
perfect
It fit perfectly and didn’t need any extra layer it was warm enough for a child who usually feel hot all the time.
Very comfortable and definitely worth every penny
Amazing value

Good quality

What is the fit of the kids' bl100 base layer pants?
The Kids BL100 base layer is cut to provide a regular fit. It is a classic straight cut that adapts to all body shapes.
What are the benefits of polyester?
Polyester is the most-used fiber for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibers can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet.
