Disana wool trousers, knitted from organic merino wool, can be used as longies over a fastened nappy without a PUL wrap if lanolised.
Once lanolised (see lanolin for instructions), provide a fantastic, natural, plastic free wrap and pair of trousers combined!
These trousers only need to be aired out in-between uses, and wash every few weeks unless dirty.
These come up big, so size down if unsure.
