Careful with that tx direct wash in. It is only meant to be used on single-ply raingear or linerless shells. If you wash this stuff into your snow gear, it will compromise the breathability of your inner liner and make your jacket and pants breathe like a plastic bag. This is consistent with their instructions.
I have used the Nikwax tech wash for the last few years and it works great, got about 100 days on my current pants and jacket with 3 or 4 washes. This stuff actually restores breathability and even waterproofing, I haven't needed to add any additional waterproofing.
If you need to add waterproofing, get the tx direct spray on, and just put in on the outside of your shit.
