Big bag, holds all sorts of stuff
Works as advertised. I prefer it when going on longer road rides to carry several tire changing supplies, and tools.

It fits my small manual bike tire pump.
I didn’t really feel like mounting my small 8.5 inch long traditional bike tire pump on my bike frame. I’ve always used a seat pack for a spare inner tube and tools + ID, cash, keys, etc. Additionally, I mount a small, rechargeable flashing rear light on the end of the bag. This bag does it all. Holds my pump and the other items. I can also mount the flashing red light on the end of the bag. I like the way this bag has two clips and straps on each side of it in order to easily strap the bag onto the bottom of the seat. The only thing I don’t like is that when the bag fully extends – the last few inches are flaccid. I suspect my flashing rear light probably points down towards the ground a little. – BUT no big deal. Mission accomplished when my bike pump fit in it with the other items.

Great & designed, from trial & use !s
Everything, but too much to write, in a word “great” ! Obviously designed and improved on over time by cyclists ! Pack all the essentials & still room for a shirt if I want to get a tan ! Very pleased !

Good size and and quality
This bag has plenty of room for all my essentials it even fit my 11″ pump and a set of full size hex wrenches.(not the stubby ones that come with a lot of kits and not T handles) The zippers work really well even the one that extends the bag to a longer length.( I watched a video of another brand of the same style bag and the reviewer was having major issues with the extension zipper.) I’m happy to say this isn’t the case with this brands bag. As far as being waterproof I just rode this morning in a steady rain not a heavy downpour but a steady rain none the less and my stuff inside stayed dry. I have a couple bikes and I can swap it from 1 to the other in no time at all. VERY HAPPY WITH THE SIZE QUALITY AND EASE OF USE

All you’ll need or want in a convenient size
Oh this works. I bought a smaller version that couldn’t my cellphone, mistake. This size is a real advantage, it carries phone, wallet, keys, first aid kit, clean wipes, and still has room. It looks sleek and sits great under the seat. The construction makes this ones that should last for quite a while. You’ll find it easy to install, takes no time. Really convenient piece of equipment.

Good waterproof bag
Even when getting blasted with water from the rear tire, everything stayed dry. There’s a decent amount of room, you can definitely fit a tube, multi tool, and wallet. The structure seems nice and durable, there’s a hard shell around the top, bottom, and back side.

Spacious and Well-Built
This saddle bag is spacious and well-built from quality materials. I liked it so much that I bought a second one for my other bike.
