I bought 2, one to attach to the handlebars, one to the luggage rack. It is very solid, waterproof, practical to use, and the eyelets can be useful. It's probably not the lightest, but that's the price of strength.

I purchased this bag to use on my rear rack (not its intended use) for day trips to hold my lunch, flask, skyline chair, waterproofs and an extra layer it serves this purpose better than a trunk bag because its extendable, waterproof and easily strapped to the rack however it could really do with an air valve to let air out as it inflates when rolling so unless you have three arms one to squash the air out and the other two to roll it down and buckle its like a balloon!, ive taken to using my forearm leant across while rolling (not so easy) to get some extra air out. another improvement would be to have the the mollie style webbing down the other side this way you could lace bungee cord to attach gear to the outer I did assume it had this from the pictures. I also think the metal buckle should be replaced with plastic, metal parts on bike bags not such a good idea when the could come into contact with bike paintwork they do look premium tho this has to be said. as a whole and for what I bought it for its very good the material used seems very durable and abrasion resistant, I would recommend just a few things stop it from being excellent

After 10 days of bike packing the volume is great but the fact that we can't compress it is a big problem… too bad it didn't have a valve like on the riverside saddle cover model

I can't use all the capacity due to the shape of the handlebar and the distance between its ends

Practical opening on both sides, fragile clips.

A good product. 2 remarks however: - the first most important +++: indeed, a valve is really missing. From the first use it is quite obvious, and even with the tutorial video there is still a lot of air despite all the efforts that can be made (in the video as well). The ideal would indeed have been a product somewhat similar to the saddle bag, which is designed as a completely waterproof compression bag. For example, I use the handlebar bag to put my floor mat and my big sleeping bag in it, but I can't compress the whole thing satisfactorily. Damage. - the 2nd but it's a detail: there is a way to secure the bag by securing it to the harness by passing the straps of the harness through the eyelets of the bag. But the strap attachment system being (super but) a little wide, it is sometimes complicated to pass them through the eyelets. But it's really detail. Brief! One more valve and it would be really perfect!

The quality-price-volume ratio is very good. I've used it on a bike trip, on the 520 touring, without the harness just using straps, and it works well and is stable enough! Of course if you ride a lot on rough terrain, it will lack stability and you will probably have to consider a harness As for the waterproofness, I could not test it in heavy rain, but there were no problems under the thins!

Even without a harness, it is suitable for attaching to the handlebars, it easily accommodates a hammock, mattress, tarp, light sleeping bag and a first aid kit, fasteners on both sides allow you to hide something handy (e.g. a first aid kit) at the end, if there is room and get to these things without unpacking the whole bag.

Used with the harness on my gravel during a one week hike and 500 kms, at the end of July, well watered! Very good bag, 100% waterproof, classic roll closure, strong buckles; Useful loop for the harness straps, which avoids lateral displacement. Very decent solidity.

Compared to other vacuums, it holds perfectly thanks to the sewn-on straps.

I just did 4 days of roaming with this pocket, I'm very happy with it. Capacity, tightness, solidity. I would say that the only negative point is to make the air vacuum. I think the next model deserves a small valid (like at topeak) to empty the air once the pocket is closed.

Good capacity
