Personally, I like the Wend gear guide better than the Gizmodo one because if focuses on the most important aspect of cold weather activities, namely staying warm. At the heart of that is excellent clothing that breathes well, is warm enough to withstand the cold temps, but doesn't leave you sweating your butt off. It is a fine line to walk, but most cold weather runners learn what works and wasn't doesn't and adjust their apparel accordingly.
Amongst the gear that Wend recommends is the Salomon XT Wings 2 trail running shoes, which they like for keeping your feet warm and dry, even in the snow. They also give a nod to the Montane Lite Speed Jacket, which is wind and water proof, and designed for cold weather exercise. The gang at Wend also likes running tights from Pearl Izumi for keeping you warm on the road or trail too.
There are more items on the list which will either help to keep you warm in the weeks ahead or would make a very welcome gift for the runner on your list. Everything from gloves to stocking caps and gaiters are listed, making it a snap to prep for the winter.
