Review on Top Quality X Large Men's Flannel Plaid Bottoms Out Clothing: A Comfortable and Stylish Choice by Dwayne Pore

As another reviewer noted, these pants are made out of flimsy material. Actually I'm not sure I would call it flannel, more like regular cotton. I find them ok as sleep pants as my house is not the coldest room so I don't need extra warm pants, but the material they are made of really exceeded my expectations. I also think it's one layer, unlike some pajama bottoms that have another layer in contact with your skin.
