Is the Leatt ADV Multitour fully waterproof?

Yes. It uses a laminated waterproof membrane bonded to the shell, so the outer fabric itself blocks rain. That is more reliable in sustained rain than a jacket with a removable inner liner.

Does it come with armor?

It ships with CE-rated shoulder and elbow protectors. A back protector is not included, but there is a pocket sized for one.

How does it compare with the Alpinestars Andes?

The Leatt is more focused on wet-weather touring with its laminated shell. The Andes offers more venting and a removable thermal liner, which suits riders in hotter climates better.

Is it good for hot weather?

Not ideal. Ventilation is limited compared with mesh or heavily vented adventure jackets, so it suits cool to mild conditions better than summer heat.

What sizes and colors are available?

It comes in men's sizes from S to XXL, in blue, red, white and gray.

Can I wear it over a hoodie or mid-layer?

Yes. The adjustable waist and arms let you size for a mid-layer, though the laminated shell has limited stretch, so try it on with the layers you plan to wear.
