I’m on my 2nd pair of MT500’s
The first pair leaked, the seat material delaminated and the stitching came apart at the crotch.
The replacement pair were the same size on the label but feel a full a size smaller.
The newer pair have a few changes to elements that were a problem with the 1st pair – more of the seams are taped, better waist tightening system. However the soft shell material used in some areas lets water straight through and the seams leak.
It is a shame as they have the potential to be really good but I simply couldn’t recommend them from my personal experience of 2 different pairs.
