Abena Abri-Form briefs are perhaps the finest adult diapers in the world. They are available in five sizes and several levels of absorbency. All feature soft standing leak guards, four refastenable tapes, and an elastic waistband for a comfortable fit. The key feature of AbriForm briefs is their incredible absorbency. Just one X-Plus brief offers up to four times the absorbency of a typical store-brand product.
