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

Great item. I use it on my morning bike rides. Easily fits my cellphone and keys. Built sturdy. Mounting on the bike is easy.

I'm liking this very much. Look and works great

This is extremely sturdy with excellent shape and very good zippers. It seems a bit smaller than the claimed 1.5 liter size, and the velcro, while super secure when perfectly aligned, is unnecessarily stiff and makes fitment a bit fussy when the seat is set fully forward. 10-15% more interior space, less dense materials, and some mounting refinements would earn my fifth star.

Light weight tool bag with lots of space. Secures solidly to seat post & its size and geometry fits under saddle and looks great

This is a nice little bag at a good price. It attaches easily and securely. This was bought for my wife's bike. I have Cannondale bag on my bike that I've had for nearly 30yrs and it does not have a mounting system that is as easy to use as this bag. I would buy this again, if mine fails.

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!

Excellent quality, easy to install, very functional, and looks great. Fits my cell phone, glasses, wallet, arm warmers. Couldn’t be happier.

Excellent saddle bag for my Giant Cypress LX. Plenty of space for my use and attaches easily to the seat post.
