If you’ve reached the point of looking at iD Slip Plus, you’ve probably already tried pull-ups and found them lacking. This is a taped brief — the format that offers the most containment — and it’s worth knowing exactly what you’re getting before you commit to a pack.
This review covers absorbency, fit, materials, sizing, and honest practical notes for families managing moderate to heavy overnight wetting. It also addresses sensory considerations, because for some children the format matters as much as the capacity.
What Is the iD Slip Plus?
The iD Slip Plus is a taped absorbent brief made by Ontex, a Belgian continence-product manufacturer. It sits in the middle of the iD Slip range, above the Normal and below the Maxi and Maxi Plus. “Plus” indicates medium-to-high absorbency — it’s positioned for moderate to heavy urinary incontinence, covering both daytime and overnight use.
Unlike pull-ups, taped briefs fasten at the sides with adhesive tabs. This means they can be applied while the child is lying down and adjusted without being pulled on. For children who find the pull-on motion difficult — whether due to physical disability, sensory aversion, or simply because they’re being changed at night — this can be a meaningful advantage.
It’s worth being direct: taped briefs carry a stigma that pull-ups don’t. That stigma is not justified by the product’s utility. When a pull-up is leaking every night, the practical case for switching to a taped format is straightforward. The iD Slip Plus is a realistic option in a market where no overnight product is perfect, and it performs better than most pull-ups for heavy wetting.
Absorbency and Capacity
iD Slip Plus is rated at approximately 1,800–2,000ml of total absorbency across the range (exact figures vary by size). For context, most children’s pull-ups — including Drynites — are typically rated around 500–700ml. Even the higher-capacity children’s pull-ups rarely exceed 900ml.
For children producing large overnight voids — which can run to several hundred millilitres in a single episode — this headroom matters. A product that reaches saturation before morning creates wet beds regardless of how well it fits. The Plus offers significantly more buffer than standard children’s nighttime products.
The core uses a combination of SAP (superabsorbent polymer) and fluff pulp, standard in quality adult continence products. Liquid is drawn away from the surface quickly, reducing prolonged skin contact. The inner topsheet stays relatively dry after absorption, which is relevant for children who are sensitive to the feeling of wetness against skin.
Sizing and Fit
The iD Slip Plus is available in Small, Medium, Large, and Extra Large. The size guide is based on hip measurement:
- Small: 60–90cm hip
- Medium: 80–110cm hip
- Large: 100–150cm hip
- Extra Large: 120–160cm hip
For older children and teenagers, Small or Medium will cover most builds. A child with a 75cm hip — roughly age 10–12 for average builds — would fall into the Small or lower Medium. It’s worth measuring rather than guessing; a product that’s too large will gap at the legs and leak regardless of capacity.
The leg elastics on the Slip Plus are well-formed. They sit close to the leg without cutting in, and the elastic cuffs are designed to create a seal rather than simply gather fabric. This matters enormously at night: leg leaks are the most common overnight complaint, and a brief that doesn’t seal at the thigh will leak regardless of how much absorbent material it contains.
The waistband has some stretch and a landing zone for the re-fastenable tabs. Tabs can be repositioned during fitting, which is useful when finding the right tension.
Overnight Performance
For overnight use specifically, taped briefs have structural advantages over pull-ups. The primary one is that the back panel extends higher and more evenly than a pull-up back, reducing the likelihood of leakage at the waistband when a child is lying prone. Sleep position has a direct effect on where a product leaks, and back-lying children in pull-ups often wet through at the back waistband — a gap the Slip Plus’s construction addresses more effectively.
The Slip Plus also distributes absorbent material across a broader area than most pull-ups, which tend to concentrate their core in a narrow central strip. For children who move during sleep, a wider distribution means fluid is more likely to be captured wherever it lands.
One practical consideration: because these are taped briefs, they can’t be pulled up and down for toileting. If your child wakes to use the loo during the night or early morning, either they or you will need to refasten. The re-fastenable tabs handle this adequately in practice, but it is a workflow change compared to pull-ups.
Sensory Considerations
For children with sensory processing differences — including many autistic children — the texture, noise, and bulk of a product can be the deciding factor, independent of absorbency performance.
The iD Slip Plus uses a non-woven outer cover that is quieter than crinkle-backed products. It isn’t silent, but it’s softer-sounding than older-generation adult continence products. The inner topsheet has a soft feel; it doesn’t have the rough texture some children object to in cheaper products.
Bulk is moderate. The Slip Plus is thicker than a children’s pull-up but not substantially bulkier than some high-capacity alternatives. For children who tolerate nappy formats without difficulty, this is unlikely to be a barrier. For children where any bulk is a sensory issue, the product market still has significant gaps that no brand has fully addressed.
If your child has strong reactions to new textures or routines, trialling a single product before committing to a case purchase is advisable. Some stockists sell individual items or small packs for this reason.
Cost and Availability
iD Slip Plus is widely stocked by UK continence retailers, pharmacies, and major online platforms. Pricing varies, but a pack of 20–30 typically runs between £10 and £18 depending on size and retailer, making the per-unit cost comparable to or slightly above high-capacity children’s pull-ups.
For families managing nightly wetting, cost per night is a reasonable metric. If a pull-up leaks at 1am and requires a sheet change, the true cost includes laundry, disturbed sleep, and the child’s comfort — not just the product price. A product that reliably contains a full night’s output may represent better value even at a slightly higher unit price.
These products are not available on NHS prescription for bedwetting in children without a continence referral and formal assessment, though some families in complex care situations do access continence supplies through their local NHS continence service. If you haven’t yet spoken to a GP or paediatrician about your child’s wetting, that route is worth exploring alongside product management.
Who Is the iD Slip Plus Most Suitable For?
- Children or teenagers with moderate to heavy overnight wetting who have outgrown the capacity of standard pull-ups
- Children who cannot or do not pull up/down a pull-up independently and need an applied product
- Children with physical disabilities where lying-down application is more practical
- Families where overnight leaks are causing consistent sheet changes and a higher-capacity solution is needed
- Children who tolerate — or prefer — a more structured, fitted product rather than a softer pull-up format
Limitations Worth Knowing
- Not suitable for children who need to toilet independently at night without assistance to refasten
- The format requires a brief adjustment for families used to pull-ups — both practically and psychologically
- Not designed specifically for children; sizing starts at adult Small, so very small children may not fit well
- Availability in smaller pack sizes for trialling can be limited in some retailers
Summary
The iD Slip Plus is a well-made, high-capacity taped brief that outperforms most children’s pull-ups on absorbency and overnight containment. It is not the right product for every child — but for moderate to heavy wetting, particularly in older children or teenagers, it’s a legitimate and practical choice that deserves to be evaluated on its merits rather than dismissed because of its format.
If overnight leaks are disrupting sleep and laundry is becoming unmanageable, the format that actually contains the wetting is the right format. If you’re exhausted from night changes, changing the product is a reasonable place to start.
For a broader look at why standard pull-ups so frequently fail overnight, the design problems that cause overnight leaks are worth understanding before you choose your next product.
