Our methodology: the Containment Security Framework

Most product reviews in this category are either thinly-disguised advertising or one-line opinions. We wanted something a man could actually rely on: repeatable, scenario-based, and honest about what we did and did not test. The Containment Security Framework, or CSF, is how we get there.

The five stages

Every review moves through the same five stages, in order. The acronym is deliberate: Identify, Protect, Execute, Evaluate, Detect spells IPEED, the same leakage standard we score against. This is a security problem, and we treat it like one.

STAGE 01

Identify

What the product claims, who it is designed for, its absorbency rating, its real cost per wear, and the exact batch we bought.

STAGE 02

Protect

Fit against male anatomy, absorbency under load, and how securely it contains leakage when it matters most.

STAGE 03

Execute

Worn through six standard scenarios that cover the situations men actually find themselves in across a normal week.

STAGE 04

Evaluate

Scored across ten categories, photographed on a measured board, and revisited at three and twelve months.

STAGE 05

Detect

Every test logs the Initial Payload Egress Event, our IPEED criterion: whether a product fails, when, and how badly. Detection continues across the living review, not only on day one.

The six test scenarios

A product that works at a desk can fail on a bike. We test each one the same way, so scores are comparable across every review.

A · Office day	Seated at a desk for six to eight hours, with the usual standing, walking and bathroom breaks.
B · Commute	Public transport, including the bag-carrying, stairs and standing that come with it.
C · Car journey	Two hours or more seated, where heat, pressure and limited bathroom access all add up.
D · Active day	Walking, errands and being on your feet, the everyday movement that shifts a poorly fitted product.
E · Overnight	Eight hours of sleep, where absorbency over time and skin comfort matter more than discretion.
F · Two wheels	Cycling and motorbike. Saddle pressure, riding position and vibration, the hardest test of containment and one few products are built to pass.

The ten scored categories

Each category is scored from 1 to 5, in half-point increments. Noise is inverted: a higher score means quieter, because quieter is better.

The Dependability score

The ten category scores feed into a single headline number we call the Dependability score, rated from 1 to 10. It is the answer to the only question most men are really asking: can I trust this to get me through the day. The category breakdown sits underneath it, so you can weight what matters to you. If you care most about discretion, read that line. If you ride a motorbike, read scenario F.

IPEED: our leakage criterion

Reviews need a shared language for the thing everyone is actually worried about. Ours is IPEED, short for Initial Payload Egress Event Detected: the first point at which the product fails to contain. We rate it on a four-point scale.

None

No detectable escape across the full test

Mild

Minor escape, contained by clothing, no visible mark

Noticeable

Escape a wearer would feel and need to manage

Strong

Failure that reaches outer clothing

IPEED is a LeakedBriefs assessment criterion. A UK trademark application is pending. There is a dedicated page explaining it in full.

Living reviews

Products change. So does a body, a routine and a wash cycle. Every review is updated twice after publication, so it reflects long-term reality rather than first impressions.

Stage 1

Initial review

Published after the first full test cycle. Scores, measurements and photography complete.

Stage 2

3-month update

How it holds up after sustained use, repeated washing, and the novelty wearing off.

Stage 3

12-month update

The long view. Durability, value over time, and whether we still reach for it.

What we will and will not publish

Minimum to publish: one reviewer, one scenario, three days of testing, with measurements and photography complete. We would rather publish a careful partial review than a rushed full one.

The self-purchased doctrine. Every product is bought by us at the normal retail price. We keep the receipt and record the batch number. We hold no relationships with the manufacturers we review, we accept no press samples, and we never run advertising from a brand whose products we cover. It is the only way a score means anything.
