excellent size and design, one small gripe
I really like the design and size of this top tube bag, I’ve used it both on my Cannondale Scalpel XC rig and my Yeti 130 trail bike and it works great. Plenty of room for phone, snacks, puncture repair tool and multi tool. Love this option for shorter rides where I don’t need a hydration pack. My one small gripe is the zippers- they’re loud! The pull and slider are both metal and they rattle against each other incessantly. I’ve learned to tuck them into the bag itself which mostly works until they eventually work their way back out and begin rattling again. This bag is a great value and perfect size, just fix the zippers!
Little bag, BIG difference!
I was looking for a small bag that gave me the convenience I needed while riding around. This was the PERFECT size for my wallet, power bank, a flash light and my garage remote. It’s small, simple and it does exactly what I need it to do. No extra fluff or gimmicks to charge an insane price. Great bag at a great price point! Great job REI! A simple quality product! A !
