TENA Slip is one of the most absorbent overnight containment options available for older children and teenagers — but it is also one of the most misunderstood. Many parents arrive at it after exhausting pull-up options, often unsure whether it actually comes in sizes small enough, whether it will fit, or whether it is appropriate at all. This guide answers those questions directly, covering TENA Slip sizing, absorbency levels, and how to work out whether it is the right choice for your child.
What Is TENA Slip?
TENA Slip is a taped all-in-one brief — sometimes called a tab-style nappy or taped brief — made by Essity, one of the world’s largest continence product manufacturers. Unlike pull-ups, TENA Slip fastens at the sides with resealable adhesive tabs, which means it is put on and removed while the wearer is lying down. This makes it easier for children who move significantly in sleep, and gives a more secure, adjustable fit than elasticated waistbands.
It is designed primarily for adult incontinence management, but several sizes fall within a range that fits older children, teenagers, and young adults with smaller or average frames. It is widely available online and through major pharmacies. For children with complex needs, it may also be prescribable — worth discussing with a continence nurse or GP.
TENA Slip Sizes: What Is Available and What Fits
TENA Slip comes in four standard sizes: Small, Medium, Large, and Extra Large. Sizing is based on hip circumference, not age or weight, which makes it more reliable when selecting for a child or teenager.
- Small: 60–90 cm hip circumference
- Medium: 70–110 cm hip circumference
- Large: 100–145 cm hip circumference
- Extra Large: 120–160 cm hip circumference
For most older children and teenagers, Small is the relevant size — typically fitting from around age 10–11 upwards, depending on build. Slim teenagers may also fit Small comfortably into mid-teens. Medium is appropriate for teenagers with a larger frame or those in mid-to-late puberty.
The overlap between Small and Medium (70–90 cm) is worth noting: if your child sits in that range, Small will tend to be more snug while Medium offers more room. For overnight containment, a snug but not tight fit is generally preferable — gaps around the legs are a common source of leaks.
Always measure before ordering. A soft tape measure around the widest point of the hips gives a more accurate result than estimating by clothing size.
TENA Slip Absorbency Levels Explained
TENA Slip is available in several absorbency tiers, and this is where the range becomes genuinely useful for heavy overnight wetting. Not all variants are equally available in all sizes, so it is worth checking stock for the specific size you need.
TENA Slip Maxi
The Maxi variant is the most commonly available high-absorbency option and is suitable for heavy overnight wetting. It is available in Small through Extra Large. For most children and teenagers using TENA Slip, this is the appropriate starting point if the reason for switching from pull-ups was overnight leakage. It offers significantly higher capacity than most over-the-counter pull-ups, including Drynites.
TENA Slip Ultimate
TENA Slip Ultimate sits above Maxi in absorbency and is designed for very heavy or continuous output. Availability in smaller sizes can be more limited depending on the retailer, so check before committing to a large order. It is worth knowing that TENA publishes approximate absorbency figures on product packaging and their website — useful if you want to compare against other products by volume rather than marketing language.
TENA Slip Plus and Normal
These lower absorbency variants are designed for lighter incontinence and are unlikely to be appropriate for overnight bedwetting in children. They are included here for completeness but are not recommended as a starting point for the use case most families arrive at this product through.
Who TENA Slip Is Most Suitable For
TENA Slip is not the right product for every child, but it is absolutely the right product for some. The families who tend to find it most useful include:
- Older children and teenagers with heavy overnight wetting where pull-ups, including higher-capacity products, have continued to leak
- Children with ASD or sensory processing differences where the secure tab fastening reduces the risk of the product being removed during the night, and where the fit can be adjusted more precisely than a pull-up
- Children with physical disabilities or complex needs where a carer is involved in changing and the tab system is more practical
- Teenagers who prioritise containment over discretion at night, where the goal is simply a dry bed and restorative sleep
The taped format is sometimes unfairly viewed as a step backwards or as a more stigmatising option. In practice, it is simply a different engineering approach — and for overnight use, where the product is hidden under clothing and pyjamas and no one sees it, the format is functionally irrelevant to dignity. What matters is whether it works. For detailed discussion on how product design affects overnight performance, see Why Overnight Pull-Ups Leak: The Design Problem That Has Never Been Properly Solved.
How TENA Slip Compares to Pull-Up Alternatives
The main practical differences between TENA Slip and products like Drynites or higher-capacity pull-ups come down to capacity, fit security, and format.
- Capacity: TENA Slip Maxi holds substantially more than most pull-ups sold for children. If leaks are happening because the product is saturating, this is the most direct solution.
- Leg seal: The combination of adjustable tabs and elasticated leg cuffs means the product can be fitted more precisely, reducing gaps. This is particularly relevant for children who sleep on their front or side — positions where leg leaks are most common. For more on why this matters, see What Happens to Pull-Up Leg Cuffs When a Child Lies Down.
- Independence: Unlike pull-ups, TENA Slip cannot easily be put on or taken off independently by the wearer. This is a limitation for teenagers who manage their own bedwetting routines, and a practical advantage for younger children or those requiring carer support.
- Cost: TENA Slip tends to cost more per unit than pull-ups. However, if it eliminates overnight laundry cycles that pull-ups were generating, the net cost difference may be smaller than it first appears.
Fitting TENA Slip Correctly
Incorrect fitting is the most common reason a correctly sized product still leaks. For TENA Slip specifically:
- Position the product centrally — the back panel should reach the lower back, not sit at waist level
- Fasten the lower tabs first, angling them slightly upward
- Fasten the upper tabs to create a flat, smooth waistband without gaps or bunching
- Check that the leg cuffs are not folded inward — run a finger around the inside of each leg opening to ensure the cuff is standing proud of the skin
- The fit should be snug but not constricting — you should be able to slide two fingers under the waistband
If leaks are still occurring after correct fitting, the issue is likely positional — related to how and where the child’s bladder empties during sleep relative to where the absorbent core sits in the product. This is a known design limitation across most overnight products. See Front Leaks vs Back Leaks vs Leg Leaks for a structured guide to diagnosing which type of leak you are dealing with and what can address it.
Getting TENA Slip on Prescription
In England, continence products can be prescribed via NHS continence services for children with an identified clinical need. TENA Slip is on the NHS Drug Tariff and can be prescribed, though what is available on prescription varies by CCB/ICB area. A GP referral to a paediatric continence nurse is the usual route.
If your child has been to a clinic and been discharged without resolution, this does not necessarily close the door on prescription products — see My Child Has Been to the Bedwetting Clinic and Was Discharged Without Being Dry for guidance on what steps remain open.
For children with complex needs, an EHCP or social care involvement may also open additional routes to funded continence supplies.
A Practical Note on Ordering
TENA Slip is available from Amazon, Boots, Lloyds Pharmacy, and specialist continence suppliers. Buying in smaller quantities initially — a pack of 10 or a trial pack where available — before committing to a bulk order is sensible, particularly if you are uncertain about sizing. Some retailers offer sample packs directly, and TENA’s own website has historically offered free samples for adult users, though availability for children’s sizing is variable.
Store unopened packs in a dry location away from direct sunlight. The absorbent core in these products can degrade if exposed to humidity over time.
Summary
TENA Slip is a legitimate, effective overnight containment option for older children and teenagers where pull-ups have not provided adequate protection. It fits from approximately age 10–11 in the Small size, with hip measurement being the reliable guide rather than age. The Maxi absorbency variant is the most appropriate starting point for overnight bedwetting. Correct fitting significantly affects performance. For families who have been through multiple products without success, it represents a meaningful step up in capacity and fit security — and for many, the one that finally delivers a dry night.
