I have had a 90% for about 7-8 years now. Alos have the pants. It is a great jacket and I wear it 90% of the time I hunt (the reason for the 90% name). It is a light jacket that is the top layer. To stay warm you need to layer under it or your freeze. Merino wool base layer, wool LL Bean shirt for most days, I can add a puffy for colder days and I also wear a Silent predator wool vest at times over it. If your looking for a single jacket to sit on stand to keep you warm your looking at the wrong piece of clothing.
