This is the perfect saddle bag, I got the smallest size. It looks great and fits everything you need, you just set it and forget it. Some highlights:
- Great design: Colors and overall design is minimal and stealthy, especially with the black-out Topeak logo on the side.
- Great functionality: It sits tightly under my saddle, I'm confident it won't fall off and it doesn't shift around at all while I ride.
- Perfect size: I was worried that the small wouldn't fit everything I need (two tire levers, co2 canister with shiny object, inner tube, and multi tool), but it does fit everything snugly so nothing rattles around when I ride. See the load-out photo.

This is the perfect saddle bag.
I originally had the Giant Waterproof Seat Bag, Large; this bag used a seat rail wedge that allowed the bag to clip on and off with ease. The build of the bag itself was perfect except for the plastic wedge that eventually broke off at the top of Mt. Evans.
And friend of mine, whom I biked to Alaska from Texas with, had the Topeak wedge drybag, which ultimately survived the journey and continues to be of perfect use.

I was upset initially because after of researching for the perfect, most durable, and waterproof saddle bag, I chose the wrong one before finding out about this one.

If you're on the edge of buying it, I would strongly suggest doing so. This thing can take a beating and survive pretty much anything. I've witnessed this first hand on a 4,500 mile journey via bike.

Do not get the Topeak drybag that is has a similar build to this one but instead has the wedge clamp system for the seat rails. The straps are the way to go.

I personally got the large version because I knew it wasn't going to be too bulky since the bag sits at an angle with your seatpost rather than sticks out horizontally.

I shopped around for a long time to find a way to carry needed tools and spare parts on my daily bike commute to work. I tried water bottle style holders but they took up the bottle cages I needed for water in S Florida. This medium size bag is made of very durable, waterproof material and holds everything I need to carry including a tire tube, 2 CO2 canisters, the canister valve, two tire levers, some first aid items, a short length of replacement chain, a chain remover, and a tire pressure gauge. I could probably fit a small bike multitool also. The moulded body holds its shape and the top has a velcro closure where it rolls down. The bag mounts under the seat, out of the way and does not interfere with my Topeak rear rack bag. It is also easy to remove and put back on, and seems it will last a very long time. I wish I found it sooner. Very pleased!

Bought the medium size and it's pretty much perfect especially since it puts an end to having to dry out my saddle bag and its contents after a rain-soaked ride. I am using it to carry a tube, small multi-tool, tire lever, CO2 inflator, 2 CO2 cartridges and a small bag of parts (e.g., misc. nuts/bolts, chain links/pins/connectors...) and there's about 1/3rd of the capacity left (maybe for keys, wallet, some food...though I tend to carry these in my back pocket). So it's a bit bigger than I need but the small size would've been too tight a fit. Fortunately it doesn't look ridiculously large nor does it get in the way of my peddling.

I especially like the quick release clips/strap for attaching the bag to the seat rails - these work so much better than velcro straps. I also like the bag's secure closure system which involves: 1) velcro to close the bag's opening, 2) folding this velcro area under once, and 3) then attaching two other quick release clips to hold it closed - it's takes more time to access the bag and then close it back up vs. via a zipper (but it's the price you pay for a water-tight bag I guess).

My only gripe (which is inherent in the bag's strap-mounting system) is that my seat post has some some sharp edges and bolt ends that come in contact with the bag. I added some stick-on felt padding in these areas so that the bag's waterproof barrier would not be worn through in no time due to this issue. BTW - For those concerned about this issue try the version that uses the QuickClick system to clamp the bag to your saddle's seat rails since it doesn't sit so closely to the underside of your saddle/seatpost as the strap-mount version (I would've preferred this version for this reason but, alas, my seat is mounted too far forward to allow the QuickClick clamp to attach to my seat rails - oh well).

I like the way its fts snugly beneath the saddle. It is well made and seems waterproof (not tested). However it is smaller than I thought so my pump won't fit. It has enough room for inner tube, puncture kit and a set of tools so does the job.

Bought this strap dry back so I could swap between my road bike and mountain bike. Would definitely recommend it.

Excelente calidad y era de esperarse por ser un producto Topeak. Yo la uso para almacenar una cámara de llanta, un par de guantes de latex, unos cuantos curitas y un multiherramienta Topeak Alien II y todavía tiene espacio como para una cartera pequeña. Compré esta bolsa pensando que la usaría para poner mi iPhone 7 plus cuando me agarrara la lluvia inesperadamente, pero en lugar de eso preferí comprar una funda especial. No me arrepiento de la compra, pues a pesar de que no es indispensable llevar las herramientas en un lugar que no se mojen, es un plus cuando sales a pedalear en la lluvia. La uso en una bicicleta de montaña Turbo Deimos W. Algo a considerar es que queda poco espacio para instalar salpicaderas.

strong quality and watertight. Rigid material makes it a little difficult to open and close. Overall I appreciate it very much.

Pros - robust, weather resistant seal, rear light strap works well & offers good light visibility
Cons - saddle rail straps should be longer for more seat post & saddle positioning choices
