The material is nice and thin, which will come in handy during the warmer months of this summer. Since it's thin, it probably won't be warm enough for me in the winter months. The fit is a little tighter around the hips than I would like my pajama bottoms to be. When I move I find it a bit tight around the hips and because the fabric doesn't stretch it tightens as I change position in bed. Review for: IZOD Men's Yarn Dyed Poly-Rayon Sleep Pants
