Although new and unused, please refrain from purchasing if you are concerned as it has been stored at home. The material feels like flannel, so I think it will keep you warm even in winter. The size is 130, but I feel like it's a slightly shorter design, so it might also fit a child who wears size 120. Long check pants, size 130, 100% cotton for comfortable wear. - Brand: CROWN BANBY - Size: 130 Thank you for looking.
