I ride down to the teens before I turn to the mag trainer and it has never let me down. Layers beneath are the key to staying comfortable...and warm, whatever "warm" means to you...
My jacket is no longer made but these two seem to the replacements...with the Expresso 3 being close but more costly than what I spend...around Senza money.

I got a Senza jacket about a month ago. With a long-sleeve jersey underneath, I think it's good into the high- to mid-30s. A good merino wool base layer should extend that down to the low 30s, possibly lower. Of course, I tend to run cooler than most folks, so I tend to layer up, sooner, than others.
