It has zippers on both sides, which is very useful for breastfeeding. The fabric is a medium thickness and not cold. It's cotton, so it's gentle on the baby. The zippers are discreet, so you can't tell it's a nursing top at a glance. The zippers open wide to the waist, making breastfeeding easy ( ´͈ ◡ `͈ ) Shipping will be compressed and sent via Yu-packet Post.
