I think footie pajamas are hot!
And they're warm too.
Men don't have to wear socks in bed to keep from getting cold feet. They too can have their own pair (or collection) of footed pajamas for bed and for lounging around the house on chilly days.
One-piece PJs are comfortable and fun and definitely not just for the girls. Just ask my husband. (But please don't tell him I told you he's a onesie wearer.)
Here is a small assortment of some of my favorite, top quality (and fun and comfortable and all that good stuff) footie sleepwear for men and some with unisex sizing for both men and women, to give you some ideas and a place to start from in your quest for the perfect PJs for yourself or your man.
