I need to have Gatorade (my favorite electrolytes) on long rides in Florida, but I hate putting the sugar in my bike bottles. This allows me to carry a Gatorade bottle in addition to my two Camelback bike bottles. Works well.

Feels like a good quality product - BUT... Mounting it to the seat didn't fit properly. Made it work but not great. Water bottle holder is very tight.Biggest complaint is I feel it touch the back of my legs while pedaling. Overall just cannot use it and will be returning.

My bike was stolen the second day I used this saddle bag, fit perfectly and held a tube and a tool set.

This is a nice little bag. It has a side pocket for small items like keys and tools. The internal compartment is small but adequate for an inner tube, a tire removal tool, and CO2 bottle for a flat. The back sleeve for a water bottle is tight but I think it will loosen up with use. The little slot for a reflector/light is not very sturdy. We put a light on it but it was so flimsy that we decided to mount the light on my wife's helmet for fear it would fall off the bag. That is the reason I gave it four stars instead of five. Other than that, it fits the bill for us. My wife has an e-bike and it does not allow for good water bottle mounting options. She had a large rack mounted bag but after 5 years decided she didn't like the look of that arrangement so I removed it and replaced it with this little seat mounted bag. All she needed was something to keep her tube, tools and a water bottle. This bag seems to have met our requirements.

Needed another water bottle holder for a triathlon coming up. This bag was affordable and offered decent compartment size and a bottle holder (albeit, a tight, and not easily accessible holder). I tried swapping bottles once empty to full for my single frame mount, and I couldn't do it while riding. So, not great for tri speed work, but whatever. I'm no pro.The mounting was confusing and not very easy. It depends on your seat, angle, where on the rails you're mounting the clip (on the flat part or the angled back side, in my case with an aero carbon seat post). So, it did not look at all like the photo mount, but it worked eventually.It's a bit wobbly, but it has more weight than my other bags, so to be expected I guess.Seems waterproof enough.All in all, a decent bag for a good price, but I don't expect it to last as long as my other bag.

I have the bag portion stuffed with a tube 2 CO2 cartridges, 1-700x28/32 tube, 15 mm stubby racket wrench, CO2 inflator, crank bros Allen wrench/ multi-tool. I have a Chrome Industries stainless steel bottle in the bag. Bag is great. No problem. It tightens up nicely against the seat and seat post. I don't even know that it's there when I'm riding. Great value and good quality for the money.

I’ve probably had 20 of these - this the best one yet. Angles nicely for full suspension
