These are my go-to commuting and cyclocross-racing gloves from September till April. While not quite warm enough for New England winter in its entirety, they do pretty darn well down to about the mid 30's or so as long as I'm not out for a leisurely ride. I swap in my lobster mitts for much colder commutes (sub-30).
The sides of the fingers on the glove are made of a breathable material, which is why these gloves do so well over such a large range of temperature.
My first pair is just now starting to show its age after 2 years of hard-use. I'll be picking up another set for next year without hesitation.
