I just got this battery run heated vest--> http://www.webbikeworld.com/r3/heated-vest/battery-heated-vest/the key is to get your "core" up to temp so your body doesnt go into "self preservation" mode and suck the blood flow from your extremities.
heated jacket liners will basically help keep your hands warmer by heating up your torso
only when their hot you can rotate the grips, i never see it as a problem just dont grip the grips so hard. their about as thin as duct tape so you won't notice the size difference, and no affect to the handeling.Dynamic213 said:I see that the grip warmer electro pads sits underneath the rubber grips. Do they make the grips slip at all? Condisering that it'll make your grips fatter, how does that affect the handling if the bike?
