Figured I'd google folks who hunt in really cold...every year
When hunting Saskatchewan in the fall, temperatures can range from 32F to -20F (0c to -30C). If you want to give yourself the best chance at harvesting a trophy buck, you need to be dressed so you can sit all day.
Layering your clothing is of the utmost of importance. Do not bring just one heavy jacket. Your first layer should contain moisture wicking abilities (synthetic). Additional layers should be made of wool and/or synthetic materials such as fleece. The number of layers will depend on your individual tolerance to the cold.
Your hands and feet are the most susceptible to cold. Bring plenty of hand and foot warmers (Hot Shots).
Layering your socks is also important. Start with a thin moisture wicking synthetic (polypropylene) sock underneath a heavier wool sock. Make sure they aren�t too tight so you have plenty of circulation for your feet.
Bring the best boots you can with the coldest rating you can find. Cabela�s makes the "Saskatchewan Pac Boot" which is a good choice. Leave plenty of room for the addition of a chemical heat pad. Boot blankets are also a great way to keep your feet warm.
There are two options for your hands being mitts or a hand muff. Large mitts big enough to allow for chemical hand warmers as well as a thin pair of gloves are the first option. A hand muff worn around the waist with a couple of hand warmers inside, along with a thin pair of gloves is also a good way to go.
For the ultimate warmth try using an old "quiet" sleeping bag. Simply step into it and pull up to your chest, locking in all your valuable body heat. A heater body suit is also a great option although not always needed.
Any hat used for hunting must be solid red, yellow, or orange. This is Saskatchewan law. We recommend a wool stocking cap (toque) that covers the ears with or with out a face mask. For ultimate coverage, try a thin balaclava underneath your wool cap.
