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 consider it after exhausting pull-up options, often unsure whether it 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 determine if 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 during sleep and provides a more secure, adjustable fit than elasticated waistbands.
It is primarily designed for adult incontinence management, but several sizes are suitable for 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 prescribed — 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, making 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’s hip measurement falls within this 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 provides a more accurate result than estimating by clothing size.
## TENA Slip Absorbency Levels Explained
TENA Slip is available in several absorbency tiers, which is particularly useful for heavy overnight wetting. Not all variants are available in all sizes, so check stock for the specific size needed.
### TENA Slip Maxi
The Maxi variant is the most common high-absorbency option and is suitable for heavy overnight wetting. It is available in Small through Extra Large. For most children and teenagers switching from pull-ups due to overnight leakage, this is the appropriate starting point. It offers significantly higher capacity than most over-the-counter pull-ups, including Drynites.
### TENA Slip Ultimate
TENA Slip Ultimate has a higher absorbency level than Maxi and is designed for very heavy or continuous output. Availability in smaller sizes may be limited depending on the retailer, so check before purchasing. TENA provides approximate absorbency figures on product packaging and their website — useful for comparing products by volume rather than marketing language.
### TENA Slip Plus and Normal
These variants have lower absorbency levels and are intended for lighter incontinence. They are unlikely to be suitable for overnight bedwetting in children. They are included here for completeness but are not recommended as a starting point for this use case.
## Who TENA Slip Is Most Suitable For
TENA Slip is not suitable for every child, but it can be very useful for some. The families who tend to find it most beneficial 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 removal during the night, and 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, aiming for a dry bed and restorative sleep
The taped format is sometimes viewed as a step backwards or more stigmatising, but in practice, it is simply a different engineering approach. 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.

## How TENA Slip Compares to Pull-Up Alternatives
The main practical differences between TENA Slip and products like Drynites or higher-capacity pull-ups relate to capacity, fit security, and format.
– **Capacity:** TENA Slip Maxi holds significantly more than most pull-ups for children. If leaks occur because the product saturates, this is a direct solution.
– **Leg seal:** Adjustable tabs and elasticated leg cuffs allow for a more precise fit, reducing gaps. This is especially relevant for children who sleep on their front or side, where leg leaks are common.

– **Independence:** Unlike pull-ups, TENA Slip cannot be easily put on or removed independently by the wearer. This can be a limitation for teenagers managing their own routines but 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 reduces overnight laundry, the net cost difference may be less than it appears.
## Fitting TENA Slip Correctly
Incorrect fitting is the most common reason a correctly sized product leaks. For TENA Slip:
1. Position the product centrally — the back panel should reach the lower back, not sit at waist level.
2. Fasten the lower tabs first, angling them slightly upward.
3. Fasten the upper tabs to create a flat, smooth waistband without gaps or bunching.
4. Check that the leg cuffs are not folded inward — run a finger around each leg opening to ensure the cuff stands proud of the skin.
5. The fit should be snug but not constricting — you should be able to slide two fingers under the waistband.
If leaks persist after correct fitting, the issue is likely positional — related to how and where the child’s bladder empties during sleep relative to the absorbent core. This is a common design limitation across most overnight products. See [Front Leaks vs Back Leaks vs Leg Leaks](https://www.sleepsecurenights.com/front-leaks-vs-back-leaks-vs-leg-leaks-a-guide-to-what-each-pattern-means/) for guidance on diagnosing leak types and solutions.
## Getting TENA Slip on Prescription
In England, continence products can be prescribed via NHS continence services for children with a clinical need. TENA Slip is on the NHS Drug Tariff and can be prescribed, though availability varies by area. A GP referral to a paediatric continence nurse is the usual route.
If your child has been discharged from a clinic without resolution, this does not necessarily close the door on prescriptions — see [My Child Has Been to the Bedwetting Clinic and Was Discharged Without Being Dry](https://www.sleepsecurenights.com/my-child-has-been-to-the-bedwetting-clinic-and-was-discharged-without-being-dry/) for guidance.
For children with complex needs, an EHCP or social care involvement may also facilitate access 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 — such as a pack of 10 or a trial pack — is advisable if unsure about sizing. Some retailers offer sample packs, and TENA’s website has historically offered free samples for adult sizes, though availability for children varies.
Store unopened packs in a dry, cool place away from direct sunlight. The absorbent core 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 around age 10–11 in the Small size, with hip measurement being the reliable guide rather than age. The Maxi absorbency variant is the best starting point for overnight bedwetting. Proper fitting significantly improves performance. For families who have tried multiple products without success, it offers a meaningful step up in capacity and fit security — often the solution to achieving a dry night.
