They really exist. Well-cut cashmere sweats that are actually cute on a person. I'm not an endorser of flying in sweats, since the logical next step is tracksuits, and only Madonna is allowed to wear tracksuits when not exercising. But these are actually kind of sexy, and unbelievably soft and comfortable. If you are doing the 16 hours from LA to Tel Aviv or the 20 hours from New York to Bangkok, or even the 11 hours from SF to Paris, thesewill serve you well.
They are pink in the photo- I would not countenance this. They do come in black, which is what they should be.

These lounge pants are made of CASHMERE the dreamiest of all fabrics.. do I have to go on!? These pants will make you feel like you are wearing a soft fluffy cloud... sigh
