-30F Rated Snow Boots, Pants, Gloves for kids--where to buy in Krakow?

I can get them here in the US for about $30 for the gloves and $60 for the boots and/or pants, waterproof, rated for -30F weather. But then I'd have to jam them in our suitcases when we come over and they're bulky.

Anyone over there know where to go there in Krakow to get these? Any idea of price or quality?

Don't they have such basic things in a supermarket like Tesco? However, I think the quality (durability) won't be as good as the product bought in the US.

Found a lot of these items at Carrefour recently, now that we are living here, but unfortunately, after the first wash in the washing machine, seams and zippers ripped or broke! y Tesco Polar fleece jacket already has ripped seams in the sleeveand pockets, too.

I was afraid of that as the prices were high and quality seemed poor.

Went to the children's store near the Meble furniture store, next to/in same parking lot as the Carrefour Zakopianska in Borek-Kliny area; found a decent pair of snow pants with zippered ankles and detachable suspenders.

Those are great and weren't too expensive. Well, expensive is relative. Higher than US prices, but decent quality. The brand was called Cool Club. So far so good.
