BTM wrote a review of Giordana Super Roubaix Arm Warmers on January 7, 2009
I bought the small size for my always cold girlfriend and they fit her skinny arms well without sliding down. I've had the same pair of Giordana arm warmers (M) since purchased for cycling in 1996-ish and they are still working great with no elastic issues and soft on the inside. Great product for warmth augmentation and very stuffable. Highly recommended item.
