I have the complete COS VTS systems Anorka. It’s designed for saddle hunters, I’m a tree stand guy, it’s the best wearing most functional hunting gear I’ve ever owned. Paired with there merino flex lite base layer, I can go from bow hunting in Alabama to late season in the Midwest with these two sets of gear. It will repel water pretty well but it’s not rainproof.
Last year I called them one morning with a couple questions Ev Tarrell the owner answered the phone answered my questions and talked 10 minutes about hunting, thought that was pretty cool.
