Lighter than the adult range. They use the same cotton but at a weight that suits a smaller garment, so they are not carrying 480GSM on a child's frame.
Do Mini hoodies match the adult styles?
Several do. The Mini Owners Club hoodie shares colourways with the adult line, including black, ash grey, cobalt, powder blue and bubblegum pink.
How should I wash a Mini hoodie?
Inside out at 30 degrees, no tumble dryer. That protects the graphics and stops the body shrinking, which matters more on kids' sizing.
