ROCKBROS Bike Seat Bag, Bicycle Saddle Bag Under Seat 3D Shell Cycling Seat Pack for Mountain Road Bikes Black

looks and feels comstructed well. Bag has reflective strips on outside making it noticeable at night and day hours.

Incredible! Love it! Large and tough, easy access.

Let’s all agree nothing is perfect. The under saddle bag is very nice. Material seems quality, the zippers are decent, Velcro straps seem well sewn and quality. Overall a super nice bag ! Roomy and easy to fill

This is the BEST bike saddle bag I’ve ever purchased. Velcro is strong. No worries about it coming undone. Stitching and material is high-quality. No worries about it ripping. Zipper is a sturdy and strong fastener. Size of bag is just right. Fits perfectly and snuggly under the seat and is big enough to hold what every cyclist needs. No need to cram things in it, or worse yet, feel like you’re hauling a suitcase along for your ride. They thought of everything. Whether you’re a serious cyclist or a casual one, this is the saddle bag for you. Buy it!

Easy to install. May require you remove rear reflector. Fits perfectly under seat.

It's hard to really write an in-depth review of an under-seat bike bag. But I'll hit the high points. I haven't tested the theory, but it seems waterproof, or at least very water resistant. The zippers move freely, and it has room for two tubes, 2 CO2 canisters, tire tools, and a dollar bill. IYKYK. The straps are long enough to mount securely without feeling like you're putting tension on them just trying to get the bag mounted. And I like that it has a spot for a rear reflector or light to mount on the rear. I may review again after I've used it for a while, but so far so good.

This bag sits up against the seat really close. and since it is a bit stiff you can fit critical items in it. I like bags that have straps while this has Velcro strips. I guess you can snug it up quicker but getting through the rail is not as easy but not a deal breaker. it has an attachment for a light which is nice even though I am sure the light sways since it is not a solid attachment. might not work so well for rear camera or radar. I do not know. has a few inner pockets so you can sperate things and I like the net in the opening part so I can have easy access to keys or money or any small item that you might want to have easy access to during a ride. A wallet is not going to fit if you have tools and bars and CO2 inflater. Maybe if wallet is small. mine is not.

Great! Good quality and just what I was looking for. It is securely attached to the bike.
