These men's pajamas or IZOD home pants are good. They are 100% polyester, very silky. Advertisement says "fleece" but it's a lightweight matte polyester, not a heavyweight fleece. They have an elastic waistband with an additional drawstring. They have a button closure instead of a button, so some guys won't like that. The ones I have are medium sized and have a 'relaxed fit' so they're roomy, but they're also long - would probably fit a person 5ft 8" to 5ft 10. They wash well and machine dry, but wash with other dark colors. Made in China.
