Basically, you take a boostable liner, which has wings, and put a wingless booster underneath it if you need to. You can use an absorbent booster and/or or a thin water resistant booster for extra security.

You can leave out the winged liner and use boosters alone if you'd rather not have wings.

• Heavy pad: Boostable liner on top, absorbent booster in the middle, water resistant booster on the bottom.

• Medium wingless pad: Absorbent booster and water resistant booster, or two absorbent boosters stacked.
• Medium winged pad: Boostable liner and either an absorbent or water resistant booster.
• Light wingless pad/liner: Any contoured absorbent booster
• Light pad/liner with wings: Any boostable liner.
