In reply to Father Noel Furlong: Was out road biking today with the 120 t-shirt under the 160 hoody, then a jersey and windproof vest. Works well - but "warm enough" for what? The 160 still feels very light - not as warm as a microfleece for example.
I'll be writing a brief review of the MeCo stuff I've been testing soon, but it'll be on another "channel".
