Amy Besch is the maker of these robes. She made and sent our FFs to us in about 10 days. Mine fit perfectly reaching to within about 8" of the floor. My wife's seemed a bit short. I sent Amy a note and we engaged in very pleasant e-mail discussion in which she insisted on correcting the length issue.
The customer service was absolutely wonderful! You can find it at thefuzzyfleece.com.
Other things the FF has proven itself great for... Getting out of a mummy bag without freezing: I use mine as a pillow. When the "urge" catches me at 3:00 a.m., I pull the hood over my head slither into my FF while I slither out of my sleeping bag. Works great! Running out to get the paper in the morning! That works, too!
But, the best use is the one it is designed for... staying warm and modest while changing from your paddle-wear to your street-wear.
The last thing I want to mention is the big kangaroo pocket in the front. It is deep enough that it will hold all of those loose things you might have... pocket knife, flare kit, radio, gps... and they won't fall out.
The only caveats I have to offer are: Don't change near nettles or burrs
Send Amy the length from your shoulders to where you would like the FF to end above the ground. If you want something a bit more "custom sized" drop her a line and ask her about it. I have no doubt that you will be pleased with the outcome.
The usual disclaimers apply... I don't have any investment in this company.
