Custom Team Bag Sampling: What to Approve Before Bulk Production
Sampling is the only stage at which a club can still change the bag without cost. What gets approved there becomes the specification for bulk, so the approval has to be a set of decisions rather than an impression that the sample looks right.

Approve four things, in writing: the build against the kit list, the colour against the coupon set, the personalisation against the proof, and the evidence that was requested with the order. Anything not approved in writing is decided later by default.
What Is Sampling Actually For?
It is for finding the mistakes that only a physical object reveals. A drawing can be correct and a bag can still be wrong — a compartment that measures right can be unreachable, a strap that is specified correctly can sit in the wrong place, and a colour that matches under one light can separate under another.
It is also the last free decision point. Everything after written approval costs money: a change during bulk is a rework, a change after bulk is a rejection, and a change after delivery is a club that does not reorder.
| Stage | Cost of a change | What is still open |
|---|---|---|
| Before sampling | Nothing | Everything |
| At sample | A re-sample and the sampling window | Everything on the physical bag |
| During bulk | Rework, and a slipped date | Almost nothing |
| After inspection | A rejection or an acceptance under protest | Nothing |
| After delivery | The relationship | Nothing |
How Long Does Sampling Take and When Does the Clock Start?
Sampling runs 6-10 working days from a signed-off tech pack, extending to 12-15 working days where the build is complex or where a new club colour has to be matched from scratch. The clock starts when the pack is signed, not when it is sent.
That distinction is worth repeating because it is where a club loses a fortnight without noticing. A pack with three blank sections is not signed. A pack with artwork that has no colour references is not signed. Both sit in a queue while the club believes sampling has started.
What Should the Club Check on the Physical Sample?
Ten things, and they are all functional rather than visual. Does it close with the full kit list in it. Does the longest item fit. Is the wet zone genuinely separated. Does the base hold its shape under load. Does the strap sit on the shoulder. Is the strap root reinforced. Do the zips run without forcing. Is the personalisation in the specified place. Is the lining the specified type. Does the bag stand upright.
- Closes with the full kit list in it, not empty.
- The longest and bulkiest items fit, at the same time.
- The wet zone is separated by a barrier, not by a fold.
- The base holds its shape when the bag is set down loaded.
- The strap sits where a shoulder is, not where it looks symmetrical.
- The strap root has a reinforcement patch and a bar-tack.
How Is the Colour Approved at Sampling?
As a coupon set rather than as a bag. The bag is one substrate; the binding, the webbing, the zipper tape and the thread are four more, and each of them can be wrong even when the shell is right. Approving the bag alone guarantees a mismatch at the trim.
The approval is made under a controlled light and, for a club bag, outdoors as well, because the bag will be photographed outdoors beside a jersey. Two conditions, one session, and the coupons signed and dated at the end of it. The method is set out in Reorder colour consistency.
| Approval artefact | What it fixes | What happens without it |
|---|---|---|
| Signed coupon set | Every substrate, in one session | The trim drifts from the shell |
| Upper and lower shade coupons | The acceptance band for bulk | An argument at goods-in |
| Dye-lot number | What the next order aims at | A fresh match on the reorder |
| Light fastness grade | Whether the colour survives the season | A fade discovered in July |
| Instrumental reading | How a dispute is settled | An argument nobody can resolve |
What Does the Personalisation Approval Cover?
Three things: the position, the size and the accuracy. The position is checked against the measurement on the tech pack rather than against where it looks centred. The size is checked against the stated cap height. The accuracy is checked against the file, element by element, on a printed proof before bulk.
The proof is the part clubs skip, and it is the part that prevents the most common rejection in the whole cluster — a name spelled as supplied, where the file itself was wrong. A proof costs a day and a re-personalisation costs the season.
What Evidence Should Arrive With the Sample?
Whatever the tech pack asked for, and a club that asked for nothing gets nothing. The usual set is a tensile result on the assembled seam to ISO 13934-1, an abrasion result on the base to ISO 12947, a light fastness grade to AATCC 16 at a stated exposure, and a coating adhesion result to ISO 2411 wherever a coating is specified.
For a school programme add the compliance evidence — CPSIA or REACH as the market requires — because a school that discovers a missing certificate at delivery has a consignment it cannot distribute.
How Should the Approval Be Written?
In writing, against the tech pack revision number, with the date. An email that says the sample is approved is enough; a conversation is not. The revision number matters because the approval has to attach to a specific version of the specification.
What a written approval has to state
- The tech pack revision number being approved.
- The coupon set, listed and signed.
- Whether the personalisation proof is approved.
- Whether the requested evidence has been received.
- Any condition attached, stated explicitly rather than implied.
- The date, because the bulk clock starts here.

What Should a Club Do If the Sample Is Not Right?
Say so specifically. "It is not quite right" produces a second sample that is not quite right either. "The wet compartment is 40 mm too shallow for a pair of boots and the strap sits 30 mm too far forward" produces a second sample that fixes both.
The second point is to decide whether the change is a specification change or a sample error. A compartment that does not match the drawing is a sample error and it is fixed for nothing. A compartment that matches the drawing and still does not work is a specification change, and that is the club's decision to make and to own.
How Many Rounds of Sampling Should a Club Expect?
One, if the pack is complete and the club tests the sample properly. Two, if either of those is not true.Three is a sign that the specification is being developed on the sample rather than on the pack, which is the slowest and most expensive way to do it.
| Round | Cause | Cost | Prevention |
|---|---|---|---|
| One | A complete pack and a proper test | The sampling window | Nothing needed |
| Two | A blank field or an untested function | A second sampling window | Fill in the pack, load the sample |
| Three | Developing the spec on the sample | Two extra windows and a slipped date | Decide before sampling, not during it |
| Four or more | No decision-maker available | The season | Name one approver |
Who Should Approve a Club Sample?
One person, named in advance, who has the authority to say yes and the brief to say no. A committee approves slowly and approves by compromise, and a compromise between three opinions is usually a specification nobody wrote down.
The named approver should be the person who will live with the bag — the kit manager rather than the chair — because the person who carries the consequences makes the better decision about whether it works.
What Happens Between Approval and Bulk?
Bulk runs 35-50 days from written sample approval, inspected at AQL 2.5 under ISO 2859-1 and shipped FOB Xiamen on T/T 30/70. Inside that window the materials are booked, the dye lot is run, the line is set and the inspection is scheduled.
The club's job during the window is to hold the artefacts and to be available for the inspection decision. A club that disappears for six weeks and reappears at delivery has given up the only two points at which it still has influence.

How Does Sampling Differ for a Reorder?
It is a confirmation rather than a development. Where the reference, the coupon set, the dye-lot record and the shade band all exist, the reorder sample is checked against them rather than approved from scratch — which is faster and carries far less colour risk.
That is what makes 300 pcs available on a repeat against the standard MOQ 500 pcs, and it is why the artefacts matter more than any other single thing a club can do. The full method is set out in Reorder colour consistency.
What Does a Club Do With the Approved Sample?
Keep it. An approved sample is the physical reference for the whole programme, and it is the thing an inspection team compares against when a dispute arises. A club that returns it, or that lets it go home with a committee member, has thrown away its own evidence.
The second copy of the evidence is the coupon set, which should be kept with the sample rather than in a different place. Two artefacts, one folder, and the programme is documented well enough to survive a change of committee.
What Is the Shortest Useful Advice About Sampling?
Load the sample before approving it. Almost every failure a club reports in November was visible in an empty sample in April, and invisible to anybody who did not put boots in it.
The second piece of advice is to approve in writing on the day. Every day between the sample arriving and the approval being sent is a day added to the delivery date, and the club is the only party that controls it.
And the third is to say no when the answer is no. A club that approves a sample it is not sure about has committed to a season of that decision, and the cost of a fortnight's re-sampling is far smaller than the cost of a year of bags that do not quite work.
How Is the Sample Checked Against the Kit List?
Item by item, on a printed list, ticked off in the room. It sounds bureaucratic and it is the single most effective check there is, because it converts "it seems to fit" into eight separate decisions, each of which can fail on its own.
The list should include the longest item, the bulkiest item, the dirtiest item and the most fragile item, identified in advance rather than discovered in the room. Those four are the ones that decide whether a bag works and they are rarely the ones a club thinks of first.
What Should a Club Do While the Sample Is Being Built?
Prepare the approval rather than wait for it. The kit list, the coupon folder, the personalisation file and the named approver can all be ready before the sample arrives, and having them ready turns approval from a fortnight into a day.
The second thing worth doing is agreeing the inspection criteria in advance. The criteria are written from the tech pack, and the pack is already signed, so there is no reason to wait for the sample before writing them.
How Does a Club Handle a Sample That Is Right but Late?
It happens when the enquiry was raised late rather than when sampling ran long, and the response is different. A late sample is a symptom; the cause is a date that was planned forwards rather than backwards.
Where the season is genuinely at risk, the honest options are to approve and accept a shorter bulk window, or to hold the specification and reorder for the following season. Expediting a bulk run is possible and it costs more than planning would have.
How Does Sampling Fit the Season Calendar?
Backwards from the first fixture, as with every other stage. Bulk is 35-50 days, sampling is 6-10 working days, and the club's own approval time sits between them and is usually the longest and least planned of the three.
A club that budgets a fortnight for its own approval and then misses it has lost more time than a production delay would have cost. The calendar is set out in Why 35 to 50 days.
And the club that plans the approval meeting before the sample is built — a date in the diary, a named approver, the kit list in the room — takes a day where the club that waits takes three weeks. That is the single largest saving available at this stage, and it costs nothing but a diary entry.
The second saving is the coupon set. Approving every substrate in one session, rather than the shell now and the trim later, removes a whole round of correspondence from a window that does not have any slack in it.
What Does a Club Do When Two Samples Differ?
Where a programme runs two samples — a pre-production sample and a shipment sample, say — the second is checked against the first rather than approved afresh. A difference between them is either a drift or a change, and the two need different responses.
A drift is a production variation and it is judged against the shade band and the tolerances on the pack. A change is a specification change and it needs the club's agreement rather than the production team's judgement. Being clear about which one is in front of you turns a difficult conversation into a short one.
How Should the Sample Be Stored Afterwards?
Flat, dry, out of direct sunlight, and with the coupon set. A sample stored badly becomes a corrupted reference — it fades, it creases and it is then used as the standard for the next order, which is how a colour that was never wrong becomes wrong.
Where a club has space, keeping two is better: one as the working reference and one retained and untouched. The retained one is the one an inspection team should be shown, because it is the only one that has not been handled.

35-50 days from written sample approval, inspected at AQL 2.5 under ISO 2859-1.
What should be checked on the physical sample?
Ten functional things, all with the bag loaded — closing, fit, separation, base shape, strap position, reinforcement, zips, personalisation position, lining and whether it stands upright.
How is the colour approved?
As a coupon set covering every substrate, under a controlled light and outdoors, signed and dated.
What is a shade band?
An upper-limit and a lower-limit physical coupon that defines what ships and what does not.
What evidence should arrive with the sample?
Whatever the tech pack asked for — typically ISO 13934-1, ISO 12947, AATCC 16 and ISO 2411 where coated.
How should the approval be written?
In writing, against the tech pack revision number, with the coupon set listed, the proof approved and the date stated.
How many sampling rounds should a club expect?
One, if the pack is complete and the sample is tested properly. Three is a sign the specification is being developed on the sample.
Who should approve a club sample?
One named person with the authority to say yes and the brief to say no — usually the kit manager.
What should a club do with the approved sample?
Keep it, with the coupon set. It is the physical reference for the programme and the evidence in any dispute.
How does sampling differ for a reorder?
It is a confirmation against retained artefacts rather than a development, which is faster and carries far less colour risk.
