It provides good protection.
Quality stuff
Works great on both leather/suede and textiles.
Does its job.
Very satisfied, works as expected.
Obviously effective, because the shoes stay dry inside without a GTX membrane.
Honestly, I don't know what difference it makes to the boots after I've polished them with Meindl wax. I think it's unnecessary.
A highly absorbent protective spray that doesn't make a mess or smell awful. It also seems to do what it promises.
A highly effective spray for all membrane shoes.
Do what is expected
