Wrangler AuthenticsAuthentics Men's Fleece Lined Carpenter Pant

Can anyone compare the warmth of these fleece lined jeans to the wrangler thermal lined jeans? i have the thermal and they are toasty and i love them

does the flannel lining ride up in these jeans, i have some that do that making it difficult to put on

How many pockets?

Are these pants extremely flammable ?
