Our Analysis

The Undercover Mama Nursing Tank works like an undershirt, except that it attaches directly to your nursing bra. Nice and long, stretchy and soft, these camisole-like tees are made of 95% cotton and 5% spandex and keep belly, back and sides covered while breastfeeding baby. They are available in the following sizing which matches traditional bra sizes:

  • Small (32-34C)
  • Medium (34D-36C)
  • Large (36D-38C)
  • X-Large (38D-40C)
  • XX-Large (40D-42)

There are 2 ways to attach the Undercover Mama Nursing Tank to a nursing bra:

  • Option 1 — To the flap of a top opening nursing bra. When the bra clasp is unlatched, the bra flap is partially opened.

  • Option 2 — To the strap of ANY bra. The hook slides effortlessly on and off the strap of the bra. With this option, the Undercover Mama will need to be unhooked for breastfeeding and hooked back onto the strap when finished.


The most commonly cited likes for this product are:

  • Covers back and tummy while nursing
  • Comfortable
  • Fits with most nursing bras
  • Long


User reviews frequently note these disadvantages:

  • May take some figuring out to put on the first time
  • Sizes run small
