The Session Tank features:

• a snug fit in all directions for most average sized newborns under 3 weeks old
• neck/arm/leg holes sized to avoid gaping
• a hidden zipper in the back for easy changing (this does not go over the head!)
• moderately opaque fabric to help hide a diaper print
• elastic at the leg openings to help keep the diaper hidden
• 100% sustainably-sourced cotton
