I wear wool as well. At this point I have only seen it in books and articles. Just wondering if it is worth it. GF Asbel has a couple photos in his book on stalking.

No need for gaiters if you wear wool pants unless you're hunting in deep snow or wet conditions, where the wool gaiters will keep the snow and water out a little longer.

The use I observed was actual strapping or lacing around the calve of the lower leg to prevent snags. Makes sense, guess you would have to find a good tension for moving around and crawling if required. Rather than using the laceing i thought the gaiters would work, while keeping the muck out.
