As with almost all baby products, there is a wide price range for snowsuits. This is also strongly related to the material properties, as just indicated with down.
A fleece overall for the much-used pram is cheaper than a waterproof ski suit filled with down.
So before buying, the intended use should be well considered. Depending on the material and brand, there are models starting at €17.99. But you can also find suits for over a hundred euros, especially when it comes to brand-name models from Steiff, Reima or Lego Wear.
However, most of the selection is in the mid-price segment around €40-50.
As babies grow quickly and can only wear the snowsuit for one season, cheaper models from Lidl, Aldi, Tchibo and Ernstings Family are a very good alternative.
Experience has shown that they can keep up with brand-name models in terms of features. The only thing you might have to compromise on is the material.
