I'm a dyed in the wool user as are many. I have surplus wool, filson, KOM, Bemidji, Stanfields longunderware, most likely some others. The KOM is my only camo wool, quality is top notch. I say most of the wool I own is higher end quality. Yes some pricier than others. I buy a peice at a time here and there and after a few years you have plenty. I thing my KOM pants, vest, jacket,hats, gloves, gaiters most likely took 5 years to buy. All my wool is used at one time or another during the colder months and I don't regret buying one peice of it. If I had a local dealer of some other Camo wool I might have bought that but the local KOM dealer was at our local shoot for years and still attends other local events. It nice to deal with local folks. All my Bemidji wool was bought in Bemidji.
Been using the Stanfield Longunderwear top and bottom for almost 20years in MN, have 2 sets. Goog value for the money. There might better wool out there these days but mine arn't wore out. Have not used their union suit.
Only problems I've had with wool has be getting too hot and not vetalting layering on and off properly.
