I had been looking for a compact comfortable daybag that was completely waterproof and this perfectly fits the bill. Ideal for keeping valuables like mobile and camera safe as well as other gear in a downpour. It is lightweight but with a slightly padded back which helps it keep its shape. The chest and waist straps are a nice addition and the fact that the waist strap can be removed is really useful as it is not normally needed and would otherwise get in the way.
I nearly bought the 15 litre version but realised that the 25 litre would be more versatile especially as the elastic cord on the front can be pulled up to compress the bag to the size required. Will easily accomodate everything needed for a day out walking.
All in all very pleased.
