I agree with most here about wool blend socks and clothing. Good base layering is important and a waterproof coat and boots. all should be breathble at the same time..
One guy said gortex is not waterproof, but most of us would disagree... my hiker shoes with gortex, have been waterproof for years, stepping into low creeks, etc...and no water gets thru...now after many years, its possible it weakens and is less waterproof, but mostly Gore-tex stuff is the best, but some other version do pretty good job too.
Here's some base layers I can get you thru tru-spec.

I sell other coats and stuff too, but you want to stay away from things with velcro pockets,...as you want more silent feature apparel... of which I don't think I have.
gortex is king, but others work well too, as I wear one of these and tested it hiking in snow in Algonquin...smaller puddles.. haven't tested heavy yet, but great boot, very comfortable for long day use !

Some folks like to wear electronic hearing pro when hunting, so they can hear them coming from further away and get ready.... and they keep your ears warm too..... may I suggest high quality model from Pro Ears, that has compression technology but at low price, the Pro 200 series. other higher end models available too, if want.

And awesome eye wear: Clarity and Ballistic protection !

I have a promo, that if one orders multiple items from all my categories, they'll get 5% off already reduced pricing, and free shipping.
There's tons of cool and quality stuff, but I do recommend your pants and coat being more silent type materials...which I don't have..
