Incase Canvas Vertical Bag / Muzetto and rain?

[ravenvii]

I'm wondering if anyone has one of those:

Incase Coated Canvas Vertical Bag

I was about to buy it, but noticed the reviews below - some people complained of rain being "channeled" into the bag by the flap design. I looked at the Muzetto, and seems their flap design is similar.

Have anyone experienced this? Is it as bad as it sounds?

There is a noticeable gap between the sides of the bag and the flap over it. I tend to carry mine bandolier-style, and when it rains water gets between the gap. When I carry it over my shoulder, water does occasionally channel down into the bag but no worse than when it falls into the bag itself. I love the bag, but it's definitely not my go-to bag when it's supposed to rain any more than a sprinkle.
