Great bag cover

Cheap and fits perfect. Even good to tuck in loose straps which hang down from my bag which I don't use, they usually end up getting caught in my spokes.

Bag Cover - Wee bit on the small side

Does the job but is only just big enough for my 30 litre rucksack I commute with, even though it's not normally full.

Quick fit Rain Bag cover

I like the new cover which I bought after I realised that the bag was not exactly waterproof, but with the quick cover which is in Bright Yellow colour plus the reflective silver patterns which makes it luminous at night - the added safety feature. It is compact so it is always in my 20L bag. And of course, the price is reasonable at $6/-.

Nedrží vršek

Pokud máte batoh, který má popruhy vedené až k vrchu batohu (švu), bude vám pláštěnka často sjíždět do půlky batohu, jelikož nemá za co pořádně držet, není jí za co navléknout. Je to spíš pro batohy, kterým popruhy začínají pod vrchním švem batohu, než na něm a je tak prostor ji tzv.navléknout. Ale je to problém spíše teda mého batohu, výrobek jako takový je při použití správného batohu funkční.

Skvělá koupě

Syn nechce nosit vestu, toto je skvělé řešení. Mohlo by být i větší, než na 30l, popřípadě delší gumička.
