BTR Waterproof Bike Saddle Under The Seat Storage Bicycle Bag

It is a small bag, but fits neatly under the seat. It is good for your important items you wish to keep dry and take with you. Nothing better really for keeping these items dry.

Good quality bag that has plenty of room for a small pump, some snacks, a spare tube and an extra layer for longer cycles. The only issue is that it does chafe slightly against the backs of your thighs while riding so I’ll only be using it when I definitely need the space.

It does the job intended Fully waterproof It can be rolled down to fit nicely under seat

This was perfect for my needs. I was worried about being able to fit my mini-pump inside, and due to its design it was a great fit - I doubt a zipped bag with similar dimensions would've been big enough. The bags "wrap-up" design and buckles allows for more flexibility. It also stays snug under the seat once fastened tightly.Lastly it has a useful loop for a rear light.Very happy with the purchase!

Simple to use. Looks understated so hopefully won’t get stolen

Its not bad, and does its job, but its not that spacious; I have keys, a spare tube and basic tools in there, and there is not much room for anything else. i cannot get my mini pump in there, and there is no room for a spare jacket or anything. Might just squeeze some gloves in but who meeds a spare set of them ? I am not complaining, because I didnt want some huge thing sticking out the back, but I was surprised how little i could get in it.

Purchased and takes all the items I wanted in it ✔️Third trip out in a couple of weeks and the seat post strap has ripped the adjuster catch right off the strap.Shame as seemed waterproof and easy to access.Saddle rail straps kept loosening when out on a ride. Had to keep tightening.Poor quality in the mounting systems in general. Rest of bag seemed good.

Like the capacity, plenty of room for tools, spare tube and cafe lock. The fastenings are chunky and secure, best one I’ve seen.
