The main difference between our two Everyday Nursing Tanks in is the chest coverage. They both offer the same smoothing support and length coverage that mimics a regular tank bottom band, but the Pull-down Tank top can be worn with or without a bra, can be worn alone or layered, and has a stretchy neckline that easily stretches & recovers for easy nursing access. The Lift-Up tank is ideal for moms who lift-up their shirts to nurse, with an open bust area that works great for moms who have to pump at work and want their belly covered when doing that at the office, home or wherever pumping takes them!
