I am glad it works for you but I can't believe that 29 is considered cold. I thought you were going to say it was in the teens or lower. I hunt below freezing and even into the teens and can stay warm enough without the HBS. The best investment I ever made was in a pair of insulated bibs and a new hunting coat. I have an Arctic Shield coat from Bass Pro, a Field & Stream inuslated bib plus I wear long johns and a fleece under the coat. With that and a good hat I stay much warmer than I ever use to in cold weather.

You mentioned your feet got wet, are your boots not waterproof? Also, what kind of socks were you wearing? Wool socks keep their warmth even when wet but I would say it is best not to get your feet wet anyway.
