We wanted to buy some high-quality lingerie for our youngest, after it has given in the cheaper clothing lines many callbacks. Convince already doing the accompanying washing instructions that high washing temperatures and also dryer are not a problem. No prints, which could consist of possibly carcinogenic substances. The only drawbacks are the use for my son myself: It is difficult to see for him how to dress around the panties, so he often times einsteigt by one leg. If he then nevertheless is properly seated, my son complained about the toilet that these panties hard high and have to be taken down, even though we have already selected a large size (he wears otherwise one or two sizes smaller). Apart from this, we are satisfied and hope for long life (as long as they fit so long).
