The bag is from OGIO, Dainese has just put its own label on it. I have had it for 10 years with daily use in winter and summer on the bike. It is still like new.
It has gone through several tests with a lot of weight and not a single seam has come apart. (Price 2014: €100)

I have had it for 5 years. Excellent in quality, space, zipper, waterproofing. Not a single seam has come undone. Daily use in winter and summer.

I have had it for 4 years with daily use and heavy loads with tools and everything you can imagine. Absolutely satisfied... many compartments for organizing things. The hard case on the top is also very useful for small items that you don't want to get damaged. It's worth every last euro. You only change it if you get bored of it.

It is an excellent quality backpack.
It has numerous compartments to put papers, glasses, tablets, coins, anything else.
I take it on a motorcycle, I put clothes, groceries, everything.
It has not been tested at high speeds, so there is no damage so far.
Also very convenient as a carry-on on the plane. You can put clothes for a few days without any problem.

The brand is overpriced now, it is a bit expensive but it compensates when you use it.
I would like to try the competition in the future.

The best of the best.. cases up to the point where you can't believe it. Very high quality.
An investment for anyone who wants to have things with them on the bike

I have it for 3 years. Although a bit expensive, it has countless compartments and you can take it everywhere

I have had it for almost two years... with almost daily use, I am completely satisfied. Also, on trips with a motorcycle and at high speeds, I did not have any discomfort with anything... in moderate rain, it also did not let water pass through. The back is quite comfortable and the straps are easy to use with a leather jacket (I say this because the leather restricts movement, so in order to wear it more comfortably, you have to loosen it completely). Personally, I highly recommend it... even at the current price... I think I bought it for 130€ if I remember correctly...

After 3 months of daily use, the straps have come off. Possibly due to weight. Waiting for a response from the Italians! Otherwise, a very nice product with plenty of space, but it lacks the quality of construction, as with a similar load, I would change the bag every 2-3 years due to wear and tear.

A little expensive but perfect quality.
Very comfortable and with countless compartments inside and outside.
And very beautiful.
