Size feeling is good

Motorcycle with Cowl on the Tandem part of the Seat, so you don't have to hit it.
The ZipperSlider in the main compartment is Single, so it is not easy to take things out from the top. But I think this makes it hard for water to get in.
There is a Belt on the SIDE that can be used to tighten the zipper, but it must be removed when opening the zipper. Also, the part of the belt that holds the excess of the adjuster is not threaded through a hole but is of the sandwiching type, so it sometimes comes off and flaps in the wind.
The Shoulder section has a Belt that can be extended, but the Belt is sewn on. Therefore, a Magic tape attachment/removal mechanism is required on the expansion parts side.
The main compartment is closed with the zipper down and the small one with the zipper up, so I have to check it many times because I am worried about it, but it is good in terms of ease of opening and closing.

It is compact but has a lot of capacity, and I like that it has a transparent zippered compartment inside for ease of use.
Shoulder section is also painless.
I carry this guy on my back most of the time when I ride Motorcycle. View detail
