These would make great cold-weather workout pants - running, xc skiing, apres etc.. Almost a legging but much sturdier with a scuba-type fabric which is very smoothing and brushed, soft inside. I'm 5'11", curvy and these fit great - very flattering on the butt. This is the 12L. Color wasn't blue as imagined but rather a really fun, bright purple! From the brand: For training in cold weather climate, lux fabric is durable and water repellent with a brushed fleece lining. Your perfect, versatile cold-weather pant. Nylon/Elastane, Water Repellent DWR fabric finish protects against light mists/snow.
