Shawn Craigwrote a review of Sportful Arm Warmers on October 5, 2015
Familiarity: I've used it once or twice and have initial impressions
I used these for the first time yesterday and the are quite warm. One thing to note is they will let the wind through. The temperature that I used them in was between 45 - 55 degrees and they were plenty comfortable. They fit great and look good as well. They have a very comfortable fleece feel on the inside with a smooth finish on the outside.
Sportful is a European company and I did need to size up to and XL from the normal L that I wear.
