I picked up a bag of Abena Abri-Form L4s from you on Saturday, and was handed a couple of samples of the Wellness briefs and asked to compare the absorbency of the two products. I wore the large Wellness Saturday night, and the Abena last night. Here's my feedback:
The Abena provides a much greater feeling of confidence, and stays dry (and comfortable) longer than the Wellness product. While the Wellness product did not leak, by the time I changed in the morning it was very soaked and I would not have trusted it to absorb any more than it did. Unscientifically, my scale says the Wellness absorbed about 1 lbs. of urine overnight.
The Abena L4 (which, I note, weighs a couple of ounces more than the XL Wellness when both are unused and dry) absorbed approximately 1.3 lbs of urine overnight, and felt almost completely dry (where the Wellness felt quite damp).
I suppose I'm somewhat privileged, in that cost (within reason) is not the determining factor when I select protection. Any cost savings would be more than offset by the superior performance and confidence I experience with the Abena products.
The Wellness brief is not a bad product. I trust it a lot more than I do Depend or generic products, and it might be a worthy addition to your product lineup. I would ask you not to stop carrying the Abena products, however, as they really are superior.
I hope this feedback helps.
