Those are 'fitted tights', meaning, they have a somewhat 'loose fit', compared to 'normal' tights. I find this extremely comfy for the trail running I do in winter.
2. Salomon XA PRO 3D Ultra Goretex running shoes. Goretex + Contagrip running sole = instant love. By the way, this doesn't mean that I'll be neglecting my Inov-8 running shoes. :)
3. For the extremely chilly runs in low temps: Vaseline. It will keep your nose from freezing off. Promise! :)
