Good fit While the fit is good, it's not as warm as I thought. December 6, 2012
Great pair of thermals! The Alpinestars thermal tech bottom is a great buy for the money. They are comfortable and will keep your legs warm. They are stylish while allowing pants to fit comfortably over them. I caution that they do run a little small in the waist. November 14, 2011
