Booster pads: what they add to a brief

A booster is a second pad you buy because the brief or pull-on you already use is the one you want to keep. It is sold to sit inside that product and add capacity. It is not a spare garment, and it is not something to hand someone in place of underwear. The listings below were recorded on Amazon when the article was written for shoppers about 55 to 80 and for whoever places the repeat order. Check the Amazon listing before buying; its price, count, and size may have changed since this article was written.

Three boosters, three different size lines

NorthShore EternaDry Booster Pads with adhesive, small, come in a 4-count pack. The page describes a booster insert with an adhesive strip meant to sit inside protective underwear or a brief. Amazon showed $6.99 when the article was written. No length or width was recorded for this small size, so a 4-count pack is a short test, not a measurement you can compare with the other two.

Attends booster pads are listed as unisex, one size, 3.5 by 11 inches, 24 count in a pack of 8. The listing says they adhere to the core of another absorbent product to add capacity, and the title ties them to other Attends products. Amazon showed $52.32 when the article was written. That price is for the listing as titled. The shape to check against your brief is 3.5 inches by 11 inches.

Tranquility TopLiner booster pads are listed at 15 by 4.25 inches, in a 200-count case. The page calls them a flow-through booster that fills first and then passes extra fluid into a brief or pull-on. It also lists an adhesive strip and a latex-free cloth-like cover. Amazon showed $62.99 when the article was written.

Those dimensions do not describe the same insert. Attends is 3.5 inches wide and 11 inches long. Tranquility is 4.25 inches wide and 15 inches long. Hold both lengths against the brief or pull-on already in the drawer before you choose the 200-count case. NorthShore’s small is a third size, with no inches recorded.

Where the booster goes in the order

Order the brief or pull-on you already know, then the booster that fits inside it. The Tranquility page is explicit that fluid moves on into the brief or pull-on. That only works if the outer product is there. The NorthShore page says the insert sits inside protective underwear or a brief. The Attends page says the pad adheres to the core of another product.

Counts change the bill faster than the unit price suggests. Four pads at $6.99 is a trial. A 200-count Tranquility case at $62.99 is about 31 cents a pad if you divide the recorded price by 200. The Attends listing is $52.32 for “24 count (pack of 8),” which is a case quantity, not a 24-pad grocery pack. Read the title before you assume you are buying two dozen.

All three pages mention an adhesive strip. NorthShore says the insert sits inside protective underwear or a brief. Attends says the pad adheres to the core of another product. Tranquility says extra fluid passes into a brief or pull-on. If the reorder note says only “pads,” the next shipment can be a long bladder pad instead of one of these inserts. Write “booster” and the product name.

A parent who already has a brief that fits does not need a new size of brief just because you are adding an insert. Change the insert’s length and width first. The 15-inch Tranquility and the 11-inch Attends are the two figures you can actually hold next to the crotch of the garment in the drawer.
