Menstrual Sleeping Pants OEM: Defining Overnight Coverage
Menstrual sleeping pants OEM projects are about disposable nonwoven briefs made for overnight wear. This page is not about washable period underwear, and it is not about incontinence garments. The specification work here concerns one question: how the front, rear and side coverage zones are defined and recorded before the first sample is cut.
Coverage is written as zones rather than as a single overall figure. Three zones are named in the brief, each with its own declared construction, and each is checked separately at review. Keeping them separate is what makes an overnight brief reproducible across a size set and across repeat orders.
| Zone | Defined by | Record item | Review point |
|---|---|---|---|
| Z-F front zone | Declared core reach, front | R-F1 placement log | First sample |
| Z-R rear zone | Declared core reach, rear | R-R1 placement log | First sample |
| Z-S side zone | Declared side coverage | R-S1 placement log | First sample |
| W-B waistband line | Declared band position | R-W1 tension log | Wear check |
| L-C leg cuff line | Declared cuff position | R-L1 position log | Wear check |
Naming the three coverage zones in the brief
Z-F, Z-R and Z-S are written into the brief as three separate rows. Each row states the declared core reach for that zone and the option code selected from our range. A brief that describes only an overall absorbency level cannot be used here, because it gives the sample team nothing to place or to check.
The zone rows are also the reference for later changes. If a buyer asks for a longer rear reach after seeing a first sample, we amend Z-R and log the amendment. The front and side rows stay as they were, so the review can tell exactly which part of the construction moved and which did not.
Recording sleep positions during a wear check
A wear check is recorded as a position log, not as a pass or fail verdict. The sheet lists the position held, the duration recorded by the wearer, and the zone observations entered afterwards. R-W1 covers the waistband line and R-L1 the leg cuff line; both are noted for each position rather than once for the whole session.
We ask that the sheet be returned even when nothing unusual was noticed. An empty observation is still a record: it tells the project file that the zone was checked under that position. Over several size codes, those records form the comparison base used when a later order asks for a changed zone layout.
Zone placement entries and how they are filed
R-F1, R-R1 and R-S1 are placement logs filled at the first sample. Each entry names the zone, the declared value from the brief, the observed construction and the initials of the person who recorded it. The entries are kept with the sample set rather than in a separate summary, so the physical sample can always be matched to its log.
Where a declared value is a range, the log records the observed position within that range. Where the brief gives a single option code, the log records whether that code was used. This distinction keeps the sheet short and avoids turning a factory record into a marketing document.
Directional checks as records, not conclusions
Directional observations are entered against the zone that was checked and the position in which they were made. They are written as notes attached to R-F1, R-R1 or R-S1. No overall protection statement is derived from them, and no zone is described as solved or unsolved on the record sheet.
This restriction is deliberate. A single wear session cannot stand for every wearer, every size code or every night. What it can do is show whether the built sample matches the declared zone layout, which is the only question a first-sample record is meant to answer.
Carrying the zone table into a repeat order
Once the three zone rows are agreed, they become part of the standing brief for that buyer. A repeat order references the brief version instead of restating the zones in email text. If the buyer changes a pack format but keeps the construction, only F-05 type packing fields change and the Z rows stay untouched.
Version numbers matter here. Each amendment creates a new brief version with a dated change note naming the row that moved. The sample set, the record logs and the artwork approval are all tied to one version, so a later dispute about which rear reach was built can be settled from the file.
What this page does not specify
The zone table does not cover material composition, topsheet options or carton quantities. Those belong to the materials brief and the channel plan, which are separate documents. Keeping them out of this page is what allows the coverage discussion to stay narrow enough to be checkable.
It also does not cover postpartum products or bladder-leak garments. Those categories use a different brief, a different set of fields and a different review route. Buyers sourcing more than one category are asked to open one brief per category rather than combine them into a single sheet.
Reading a zone record across two sample rounds
A first sample normally produces a short record sheet: five rows, one for each Z and W or L line, with the declared value and the observed construction side by side. A second round, if one is requested, produces the same sheet under a new version. Placing the two sheets next to each other is the simplest way to see what actually changed between rounds.
The comparison is made row by row, not by reading the summary notes. If Z-R moved and Z-F did not, both facts should be visible in the tables. A summary that says the rear coverage was revised is less useful, because it does not tell a later reader whether the front row was rechecked at the same time.
Sleep-position logs from the two rounds are filed with their own sheets. A position that was checked only in the first round is not carried forward as though it covered the second. This habit matters most for repeat orders: a buyer may ask for the same layout a year later, and the file then shows exactly which positions and which zones were observed for the build they are reordering.
