Features & Benefits
The UP360 Adult Reusable Swim Brief is reusable incontinence swimwear designed to be worn discreetly underneath regular swimwear.
It is made for adults who need support with solid bowel containment while swimming, using hydrotherapy pools, going on holiday or taking part in water-based activities.
This swim brief is not padded and it is not absorbent. It is designed to help contain solids in the water without adding bulk, weight or sagging.
Important sizing advice
Please measure before ordering. UP360 swim briefs need a close fit around the waist and upper thigh to help with containment.
Measure your waist and upper thigh where the leg opening will sit. Do not choose by clothing size, gendered sizing or another swimwear brand’s size guide.
If you are between sizes, the smaller size may give a more secure fit for containment, as long as it is still comfortable and does not dig in.
Not sure which size to choose? Send us your waist and upper thigh measurements and we’ll help you find the right fit.
Please note: UP360 sizes are based on body measurements and do not directly match Kes-Vir swimsuit sizes. Always use the UP360 size chart for this product.
Adult size chart
| UP360 size | Waist | Upper thigh |
|---|---|---|
| Adult XS | 56 to 86 cm | 38 to 56 cm |
| Adult Small | 66 to 91 cm | 43 to 58 cm |
| Adult Medium | 76 to 102 cm | 48 to 64 cm |
| Adult Large | 91 to 117 cm | 53 to 69 cm |
| Adult XL | 102 to 127 cm | 58 to 73 cm |
What this swim brief is for
The UP360 Adult Reusable Swim Brief is designed to help contain solid faecal matter while in the pool. It can be worn underneath a swimsuit, swim shorts, tankini, rash vest or other regular swimwear.
It is not designed to absorb urine and it will not contain loose bowel movements or diarrhoea. Like all swim nappies and swim briefs, the fit around the waist and legs is very important for the best containment.
It can also be used as a cover over another continence product if this is preferred or needed before entering the water. Please check with your swimming pool or hydrotherapy provider if you are unsure what they allow.

2nd pair we’ve bought and well worth it ,my daughter loved the pink ones but loves the blue ones even more
Thank you so much for your lovely review, Gary.
We’re really pleased to hear this is your second pair of UP360 Adult Reusable Swim Briefs and that your daughter loves the blue ones even more than the pink.
It’s great to know they’ve been well worth it.
Many thanks,

Service and contact wonderful and fastand very helpful. Panties are great. I highly recommend this store⭐️⭐️⭐️⭐️⭐️
I have been using these swim nappies for many years for my now 25 year old special needs daughter. They are reliable and long lasting. I have a hot tub in the garden so during the summer months they are used almost daily. When used in the hot tub they last about 2 years, but a lot longer when used in a swimming pool once or twice a week. My daughter is a size 16 in trousers/knickers and I order a medium size for her, they are snug but need to be for containment.
Bought second pair for my daughter. The product is very good quality and lasts longer after rigorous washes. Will definitely buy again.

These are a perfect product for my daughter, and are the second pair we've bought, due to out-growing the original pair. The quality and fit are superb and the delivery was super quick. 😀👍🏻
