I love this coverall.
I asked for it as a Christmas gift, for wearing when I blow snow.
I bought a 4x ( I wear a 3x biu figured i would need to layer under it. As it turns out, the insulation is so good, I slip it on over underwear and socks and it keeps me warm enough to get the job done.
The zipper on the pants legs makes it easy to put on large boots and zip the leg around it. Tall collar is great for blocking the wind.
I know it's mainly a practical gift, but I every time I use it I think: now this is gift that keeps giving. Totally worth it.
