I live in the Willamette Valley of Oregon. Our winters are mild compared to other parts of the country. It does get down into the teens and twenties from time to time but the coldest I've ever seen after living here for almost 40 years, was 9 degrees. This year we have been in the 20's a few times. This morning it was 22 when I went out for a 27 mile bile ride. It as sunny and there was no wind. I wore long johns tops and bottoms under bike pants, long sleeve bike shirt, a sweater and and a windbreaker. Merlino socks and sock liners and shoes covered my feet. Claw bike mittens and thin gloves covered my hands. A bike hat and balaclava covered my head and face. I was quite comfortable. I love this weather for biking. By the time i arrived back home I was quite warm as the temperature went up to 36.
