I went ahead and bought a couple bags of Fab Sense to try. It was a bit of a disappointment.
The shell, pad, tape panel, leak guards, leg gather elastic, and tape layout looks identical to ABU's Space model. The padding is lighter, and has little to no sap, so it doesn't feel very thick, is very flexible, doesn't swell at all when wet, and left my skin feeling damp all night long till my morning change. The inner sheet was slightly abrasive, somewhat like the feel of cheap paper towel - not uncomfortable, but noticeable. It also only has waist elastic in the back, not in the front, but the fit and comfort were still okay. There's also a "sterilized" odor to the diapers, it's distinct like that smell when you're in a hospital, not sure if that's a disinfectant or what, but I did notice it. Capacity is significantly less than Space. I think they quote 3000mL on the package, and that's complete nonsense. (a lot more inflated than even a lot of 'rated capacity' numbers we see)
I won't be re-ordering them. (especially considering the premium price, well above what will get me a much better diaper from ABU)
