This review is from: VeloChampion Slick Bike Seat Pack - Black, Blue, Red or White Saddle Bag (Misc.)
This pack is made from fairly thin, cheap PVC. Sadly, so are the velcro straps that loop around the seat rails. If you carefully pack it with the usual multitool, tyre levers, inner tube and so forth, it will work ok for a while, and then fairly suddenly, the straps will start to split. You'd better hope that the seat post strap is snugly fitted and that it doesn't tear itself free from the bag when the other straps go :)
It's probably a fine pack if you just want to carry a pertex and a tube of powergel, but I wouldn't put tools or anything heavy in there, and I certainly wouldn't trust it with a mobile phone. Probably better to go with a sturdier but boring-looking black nylon pack, that won't become brittle as quickly.
