That's a great fit for that bike size and tank shape. And being able to anchor the bottom straps under the seat is so much better than having straps down the side of the bike tied to the frame. Almost looks factory. Nice bike too.
The bag looks nice, and the price is good. I had one for about three months a few years ago, got it on a great deal with my Pilot Panniers at the time. Not being waterproof was the deal breaker for me. - Frank
Thanks for the review. I'll probably get the small one for my 390adv. I see that you got what looks like the comfort powerparts seat. I know the stock seat is garbage and I bought the 1 piece dirt-style "high" seat and it's not a whole lot better. Is your seat actually good for long rides?
I think the small one is perfect for this bike. Honestly for my butt the comfort seat doesn’t seem that much different, but everyone’s butt is different. I think the best thing that makes the biggest difference for long rides is padded bicycle shorts. They make all the difference!
