Lately I've been finding that my bathrobe has been saving me from a big chill after the shower in the morning and evening, so I decided to do a little research into what might be the best choice now. My current robe is a W Hotel Robe from 10 years ago. It's been great. That said, it is threadbare and no longer available.
Like I said, I did some research. If I wanted to get something better right now, I'd get this one by Wings & Horns and the ACE Hotel. It's heavy, cotton, soft (with washing if nothing else) and grey, instead of white. I like that.
