Heated gear is awesome, should have bought it a long time ago. I'm running Firstgear socks and pant liners, Warm N Safe jacket liner, Gerbing T5 gloves, and a Warm N Safe wireless troller (infinitely better than the Gerbing wired one, no comparison). Great setup, have cruised all day long down to 5C without getting chilly which says a lot for me.
Still commute every day and do longer rides on the weekends. Bike isn't going to sleep until they put a heavy layer of salt on the ground.
Nice set up. Can do 200kms+ on a single weekday rides with heated gear. Then use it for downhill ski ing. Would never consider not using heated gear. Common sense.
Makes for a longer season without trying to be Macho and suffering the cold.
