I bought a pair of zebra footed p.j.s for myself and started wearing them in the evening to watch t.v.  My husband was constantly eyeing them and wishing he
had the same warm feet and legs as I was experiencing - so knowing he wouldn't wear an animal print, I bought these camo print pjs.
The camo is a light color as to distinguish it from hunting gear.  The drop seat is another benefit to the men's style; the women's styles don't have that.
Why?  I don't know....but he is quite happy with this lounging outfit.
