http://www.montbell.us/ This is a company I like for outdoor clothing. Their products are very high quality but not cycling specific. I have one of their light weight insulated jackets. It weighs a mere 8 ounces which is slightly more than a tee shirt but is as warm as a fleece jacket and packs down to the size of an orange. There is a range of similar jackets of increasing weight and warmth, with hoods or without and prices are reasonable. They also have base layers in polyester or merino wool. I would urge people to poke around their web site.
