The sweat pants are perfect for running. No need to put a jog or legging it, you can wear it alone because it is "stylish" (do not look like a granny girdle ...) and it is very effective in terms of sweating (I tested other Sports signs of impermeable suits in France). Too bad it comes to mid-calf and not to the ankles, but I offered the sleeves / leggings matched on this site and it is also effective for running (nice to have ankles tidy and warm!). Too bad also that the side pocket is made for the Iphone and not for phablets market, but knowing that it is the only fitness long pants that I found on the Internet and in physical stores, it is already super and I do not demand perfection, it suits me :-) The size correspondence in cm correspond to reality: X-SMALL, hip circumference 84-94 cm, waist circumference 56-66 cm, length 80 cm.
