Please also bear in mind that under heavy activity - despite increased
blood flow and blood pressure - may result in a net loss in volume due to
fluids being squeezed out of the residuum in reaction to forces. I
experience this with activities beyond intermittent running in intensity.
That feeling of looseness may not be entirely related to material
changes in the liner.
As for sweat, I don't have as much in the Alpha as I did with silicones
with or without neoprene sleeves. I did get a bad case of leg farts, but
found out that was on the outside of the liner and fixed by wearing a
thin sheath so air could escape more quietly.
