I have the A5 stretch alpha jacket and I think it’s one of the most well thought out detailed pieces of clothing I’ve bought and I own a lot of Sitka/FL and the sort. I was able to visit the store in Seattle where they also produce the stuff and speak with Rick who is I believe thier CEO. Good guy who was a no BS sort of dude, prior army guy and was passionate about what he does. The special forces community orders a lot of their gear.
I think you’ll find the items to be great. I plan on ordering their puffy jacket and another piece or two in the future including the rig lite pants.
Journal of mountain hunting has a podcast with the CEO as a guest and gives a good overview of the company.
