Heat Grips vs Gaurds vs Hippo Hands

[Gas Man]

My FIL wants something for his 82 Yammy XS400J to keep his hands warm in the morning (30* ride in), cause his afternoon ride home is nice. (He lives up north). These are my ideas, but want some input or other ideas.

For heated grips, I know my HD dealer has been selling these very well.

Heat Demons

Ebbs has some wrap around style that I'm not sure about.

Dirt/dual sport guys... what brands for hand gaurds?????

Then... No Worries fav.

Hippo Hands
