First use and aftercare: The type of waterbased print used requires a pre-treatment to be applied to the garment to prevent the ink spreading too far into the yarn and edges becoming less defined. The pre-treatment can leave a slightly oily residue that washes out entirely on a quick 20min cycle. However, the garment is perfectly fine to be worn straight away so in order for us to do our bit for the planet we have decided not to pre-wash the garments and to leave the decision as to when to do that in your capable hands.
