Although warmth is comfortable, if you use it several times, it will be misaligned by bending and stretching your legs. I think that it would be nice if there is a misalignment prevention with Velcro or something.
Maybe expectation was too high, but I was disappointed. If you are equipped with winter socks and the appropriate first layer, middle, outer, you can hardly see the effect. I do not know if it can not be dressed very suitly, but I currently wear it in house wear but I think that it is not very suitable for use in northern countries.
Various leg warmers are on sale, but the first thing is that there are many woolen materials, and the bottom of the trousers is badly damaged. This leg warmer is perfect for your feet and is warm and light. Since it does not go bumpy under the trousers, boots can also be worn normally. I feel comfortable and good comfort, so I have been repeating it several times. I also want my arm.
