My SIL once bought herself, my mom and me the same velour robe, but in different colors. Carmen's was red, Mom's was purple and mine was dark blue. She got 'em at JCPenney's - velour, zipped up most of the front (you still had to pull it on over your head or step into it) and nice, VERY nice pockets. Loved that thing. The elbows wore out first. It eventually died.
Of course, JCP doesn't carry that style any more. Now, for the winter, I have a stupid, long, fleecy hoodie that zips, but the zipper separates so you slip it on like a regular jacket. I hate it. For warmer temps, I have the old-woman standby of a "duster" - you can still get them! - snap front, easy care fabric, pockets.
