Replaced my saddle bag with this and very happy. Easy to remove and lay out on ground for easy access what I need for flat fixes, etc. very secure as well - doesn�t jiggle and rattle like a bag.
Also fits my saddle rails where many others don�t. My saddle sits fairly forward on an aero post (Cervelo S5) so not much rail access for placing a bag. This fits great and doesn�t have to attach to the post.
Item works as described. Enough room to hold two road tubes, a multi-tool and other small items. Velcro closure is secure. Prefer this item over a traditional seat bag.
About as good as they come without something very high end. Wraps tight... not going to get much more than the basics in it and of course will start making holes where your CO2multitool and seat clamp rub. Overall fine for roadie kits.
