During my trip, the Alberta weather turned extremely cold, recording all time record lows. The average low was 15 to 20 degrees below zero with highs of 5 to 15 degrees below zero. The use of the IWOM Parka enabled me to be able to sit in my stand from daylight to dark. Without the IWOM Parka I don't think I would have been able to complete my hunt and harvest a great buck.
