Kinco mittens are super warm and super cheap. They're not the most stylish or technologically advanced, but with some simple waterproofing, they get the job done. I use them as a backup pair for when it's really wet outside.
Quality goggles will be tough to find under $50. If you are looking at premium brands, Dragon and Spy seem to be the least expensive entries into that category.
This is a large? Same seller, Kinko International.
