Review: Great bag! - I really like this bag! It’s rigid, so you don’t have sag. I’ve had it for a couple of years and it’s held up to my limited use. Haven’t tested it in the rain. Zippers are good. Holds a lot of stuff! I usually keep it full of tools and tubes and pump and other repair stuff. The Velcro straps keep it very secure, and it’s easy to take off and take with you. I highly recommend this bag.
Review: GREAT BAG, PERFECT FOR ME! - I bought this to replace a 25 yo Trek bag that was always bigger than I needed, and, though still completely intact, was begnning to sag a bit on the sides. I decided to try a hardshell, because of the clean, streamlined appearance, and after looking at several, chose this one, wisely, I think. The deciding factor for me was the fact this one was higher in the front, tapering to a lower profile in the back, whereas the others were just the opposite. It seems to me not only a more logical shape, functionally, but also a more aerodynamic, and attractive look. The new bag also afforded the opportunity to clear out many things I've been carrying for years, but have never used, transferring only those items that have potential utility. It's just the right size for me, seems of good construction, straps on tightly, and includes quality zippers. I really like it, and look forward to many years of service.
