Where to begin. These leggings are amazing. Love all the pockets. I've been wearing mine while working in our warehouse and they are super comfy, warm, durable and functional. The fit is true to size, I wear an XS is all their leggings. By far these are the best fleece lined ones they have come out with. I have ones in black and gray from previous seasons and hands down these ones are the best. They have more stretch than years prior, but also feel more durable. I've worn them for work and out hiking so they are very versatile. Stick with these and come out with more colors!For reference I am 5'8, 125 lbs, athletic build.
