Matterhorns
I have a pair of matterhorns that I bought at the Clothing Sales store on Ft. Knox in Janurary 1992, before shipping to Germany. I also used them as a SF candidate here in the hills of Utah, and honestly have only pulled them out prior to hunting season to make sure they're soft for the last few years. In the last ten years, I have kept them clean, and applied mink oil a few times. The stitching is holding up, and the inner shape is still very comfortable. 100% waterproof, still warm, the soles are beginning to show significant wear.
I know they are the govt contract of the Ft. Lewis boots, and I've wanted to try those. If they are better than these boots, they must be very good indeed.
