These saddle bags are a decent temporary bag. I say this because I have had them for only one season and the zippers on both sides have already started to come apart. They work well but I feel they would be best used on an as needed bases and if you plan on needing something daily as I do to store my lunch and safety gear each day the zippers seem to wear out very fast.
However, installing them was easy and they are very lightweight so I didn't even notice them when I put them on the bike!

I have a sportsbike, that doesn't have much storage. This allows me to carry much more around. It's too small if you are considering using this as suitcase for long adventure, however perfect for everyday commutes and small errands. If you need to give a passenger a ride, no problem, just unclip it and let them wear it on the back, acts as extra protection too!

update: after about 6 months of ownership, still holds great, but the color faded.

Attached are some pictures. For scale, my helmet is a XL and my lunch box is one of the bigger ones you can get, an unusual size that's bigger than most cloth lunchboxes.

This advertises that a helmet can fit, but mine is a pretty common helmet (Scorpion line) and at XL it does not fit. Well, it fits but it won't zip completely. The picture attached shows the helmet in and as far as I can zip which isn't far at all. I'm sure a L would fit, but I can't say for sure.

On the flip side, my large lunch box does fit! Which is what I wanted this for, mostly, for those items that I want to carry with me while I'm actively riding.

The helmet not fitting is not that big of a deal because I usually take my helmet with me wherever I go.

Which brings me to my next point"¦

This is not very well secured to prevent theft.

You can get put a small, TSA baggage sized lock on the zippers, but all a thief needs to do is unbuckle the pack from the attached straps and walk off with the whole bag and then destroy the lock in a secure place. There is NO way to secure those straps.

The straps do make it so someone can't just up and take the bag off your bike in one go and it also does keep it secured while riding. I've put about 100 miles on my bike with this thing on and it hasn't come off yet. It's still snug in there. Max speed I've gone with this on is 80 MPH to further give you an idea of how well it stays attached without falling off.

It is universal so likely will fit your bike. This is attached to my 2022 Kawasaki Ninja 650 and it fits well under the rear latching compartment. It does take up my backseat, so no riders will be able to sit back there while this is on. But the pack does come with backpack straps, so you could either wear the pack or strap it to your passenger.

I see the waterproof cloth and it seems to be made of decent quality. It has rubber elastics all around so it should fit very snug under the bag to keep it in place in case of rain.

It has made it slightly more difficult to get onto my bike as I would usually have to glide my leg over my back seat and that's a little more difficult with this on and will be even more challenging with something like my lunchbox in it. But it's not impossible to get on even by yourself without help.

All in all, it's great and I like it. I like that it has reflectors on it which will also help keep me more noticeable in darker environments too. They're not extremely noticeable, but it adds to what I already had just a tad without being too much.

Holds a decent amount of groceries and comes with backpack straps incase you want to use as a helmet bag and make your backpack wear it as a backpack. Amazing bag for the price.

Straps are not good but bag overall is good quality. I had to use extra bungee cords that came with it
