I would think it would be fine down to about 25 degrees if you're being active (cycling) and it is windproof and water
resistant. I think with a full zipper in front, you should be able to adjust your ventilation. With it being so light weight, I would imagine that it would not lay on your back if you were riding 10+ mph with it fully unzipped.
Patagonia Men's Nano Puff® Jacket
Way, way too hot for cycling. This is meant as an insulation layering item for sports like skiing.
At 25F, I wear an Aerotech thermal jersey and a light weight capilene base layer under a soft-shell jacket.
I have one of these patagonia jackets like you note above. You're going to want something lighter and better wicking for aerobic sports in winter time.
Great jacket though. It's one of those jackets that everyone should have if you are doing things like skiing etc...
