Looks good.

I bring more clothes than that - a down jacket and at least one more warm long sleeved shirt, to wear in camp if your other long sleeve gets wet while riding. Also I really like arm and leg warmers. Clothes is where I overpack the most, though.

This multitool is the one I use and it has a chainbreaker (no idea if it's a good one, haven't had to use it yet.)

And I really like having a separate knife for cooking, just a little utility knife - sucks to get peanutbutter on your multitool.

Have a great trip!
