Spasilk's bodysuits are made of thick 100 percent extra soft cotton that your little one will love. Lap shoulders and snaps at the crotch make for a stress-free changing experience. Sizing and fit have been drastically improved: lap shoulders fits snugly around the neckline and sleeves have been resized to an appropriate length for each age range. Length is slightly longer to counter dryer shrinkage. One wash and dry cycle is recommend before first use for optimal fit.
