These flannel lined pants are tough on the outside, but soft and warm on the inside. Kinda like a 3-day old donut you just micro-waved. Of course, we dont use donuts to make our Flannel Lined Original Pants. We use a 12.5 oz. pre-washed, ringspun cotton canvas just like our 12 oz. Original Tree Climbers' Pants, but we also add in a gusseted 4 oz. Flannel lining. That keeps you nice and cozy whether youre working in the cold or just out to have some fun.
