So far I have only worn shorts and t-shirt under my scent suit this year. South Central Texas is usually warm enough you are forced to take you kill to a cooler/locker to keep it fresh. I don't care for bitter cold and have always wondered how strong ones hunting conviction must be to endure such weather. Glad to see technology has given you guys some help! I would really like to track a blood trail in the snow but haven't had any for more than 16 years.
