I've got a Stoic Welder Lo Softshell and although I read down there that the lining shouldn't be exposed to the stuff, does that apply to my jacket as well? There isn't any fleece, but I'd like to be sure.
Wash away...but clean it with plain water or Tech Wash first.
Softshell Proof is perfect for your jacket and the wash-in is SUPER easy to use (I use it frequently) and very effective. Like Phil said, you definately want to clean it with Tech Wash before proofing (the proofer can't adhere to dirty fabric). If you have any more detailed questions, don't hestitate to call us @ 800.563.3057. Thanks for the question. Stay dry!
I use the "Nikwax Softshell Proof Wash In" on a softshell jacket and it become rain proof. and I dont have a problem of wicking sweat on the trails
Just go for it (:
