Short answer
Tab style adult diapers, also called tab briefs or adult briefs, are absorbent garments that fasten at the sides with tabs, either adhesive tape tabs or hook tapes, instead of being pulled on like underwear. In U.S. regulatory terms they are a “protective garment for incontinence”, a Class I device. The tab details worth reading on a specification page are the closure type, whether the tabs can be adjusted and where they sit on the hips.
Definition and scope
The U.S. FDA classification regulation, 21 CFR 876.5920, defines a protective garment for incontinence as “a device that consists of absorbent padding and a fluid barrier that is intended to protect an incontinent patient’s garment from the patient’s excreta.” The same section states that this generic type of device “does not include diapers for infants.” Adult tab briefs therefore sit in a different regulatory category from baby diapers, even though the everyday word “diaper” covers both.
The regulation places the device type in Class I (general controls) and exempts it from 510(k) premarket notification, subject to the limitations in 21 CFR 876.9. It is also exempt from the quality management system regulation in part 820 except for records and complaint files (820.35). For a supply buyer this means that a brief’s classification is a regulatory fact that is the same for every brand, so it does not separate one product from another.
This page covers the tab closure itself. For the broader decision between product formats, see the adult incontinence product selection guide. For how manufacturers’ size charts are organised, see the adult diaper size chart guide.
How the tabs work
Manufacturers use two closure vocabularies, and they are not interchangeable on a spec sheet.
- Tape tabs. Tranquility’s size guide describes its briefs as the tape-tab style and separates them from its pull-on “Protective Underwear”.
- Hook tapes with adjustable tabs. The TENA US page for TENA Super Briefs lists “Adjustable tabs” as a feature: the tabs “can be repeatedly adjusted to ensure the best fit”, described as “hook tapes that are easily adjustable to get the best fit.”
The two sources show that the same product family can be described as “tab”, “tape” or “hook tape”. A page that names a closure but says nothing about adjusting it has not told the reader whether the tabs can be refastened.
Tranquility’s guide gives one fit cue for briefs: “Brief should fit snugly with the placement of the tape tabs on the hips and no gaps around the legs.” It measures the widest part of the body between waist and hip, in inches, and states: “Sizing is not always perfect; the sizes shown are recommendations, not a guarantee.”
Tab style versus pull-on
The clearest sourced difference is that manufacturers treat them as separate product lines with separate sizing documents. Tranquility publishes one size guide section for briefs and another for protective underwear. The fit cue for the pull-on product differs: the underwear “should fit snugly touching the crotch with no gaps around the legs”, with no mention of tab placement because there are no tabs.
Both cues agree on one point, no gaps around the legs. Only the brief cue depends on where the tabs land. TENA’s Super Briefs page lists waist ranges by size in inches for its tab product, which is another reason to read the size basis for the specific format rather than carry a size across formats. The size chart guide linked above covers the sizing side in full.

Each row below is a field to look for on a manufacturer page or case label, not a quality ranking.
| Field to read | What the sources show | Source |
|---|---|---|
| Closure wording | “Tape tabs” (Tranquility) and “hook tapes” (TENA) both appear for tab briefs | Tranquility Size Guide; TENA US |
| Adjustability statement | “Can be repeatedly adjusted” is stated by TENA for its tabs | TENA US, Super Briefs |
| Tab placement and fit cue | Tabs on the hips, no gaps around the legs | Tranquility Size Guide |
| Measurement basis | Widest part between waist and hip (Tranquility); waist ranges in inches by size (TENA) | Tranquility Size Guide; TENA US |
| Product category | Protective garment for incontinence, Class I, infant diapers excluded | 21 CFR 876.5920 |
Facilities that stock several formats can use the same fields when comparing a brief against a pull-on line. For planning supplies across a whole ward or unit, the nursing home supply checklist and the guide to bulk adult diapers cover the wider context, and what underpads are explains a related product that is often listed alongside briefs.
Common misunderstandings
- “Diaper” means one regulatory category. The FDA regulation explicitly excludes infant diapers from the adult device type.
- All tabs are the same. Manufacturers describe them differently: tape tabs, hook tapes, adjustable tabs. Only some pages say whether tabs can be refastened.
- A size is a guarantee. Tranquility states that sizes are recommendations, not a guarantee.
- The tab style and pull-on share one size guide. At least one manufacturer publishes them separately.
FAQ
What are tab style adult diapers?
They are adult briefs that close at the sides with tabs rather than being pulled on. Manufacturers describe the closure as tape tabs or hook tapes.
Are adult briefs regulated differently from baby diapers?
Yes. 21 CFR 876.5920 covers protective garments for incontinence and states that it does not include diapers for infants. The adult device type is Class I and exempt from 510(k).
Can the tabs be adjusted after fastening?
It depends on the product page. TENA states that the tabs on its Super Briefs can be repeatedly adjusted. Check each product’s own description.
Where should the tabs sit?
Tranquility’s guide says the brief should fit snugly with the tape tabs placed on the hips and no gaps around the legs. A clinician or the care team can advise on fit for an individual.
