Roll Top Waterproof Backpack?

[Vikeonabike]

Due to the amount of Electronics I'm now carrying backwards and forwards to work I'm after a fully waterproof back pack. Any recommendations?
Looked at Polaris Aquanaught, Oxford Aqua V20, OverBoard so far.
Has anyone got the Lidl Special?

Tried this one?

Yup - I have this and carry phones (x2) and my laptop through all weathers

I have one of these and it is excellent and comfy.

I use an Overboard - the 20l pro light, it is a brilliant bit of kit, lightest rucksack I've ever had, comfortable and kept my kit dry in torrential rain.

To be totally fair I should point out that I have a connection with Overboard, but I still would recommend it regardless

I just place a drybag in backpack/pannier.

Look up "Boblbee"
They are generally hard shell back packs but tough as old boots and extremely comfortable no matter how full and heavy they are.

Whilst I like the rucksack (my favourite one to fit my back), the actual bag isn't that padded and I'm not sure I'd want a laptop in it, unless it was in a fairly padded case. Mine has been going for about 9 years now.

I loathe my Polaris Aquanought.

A brand called Lomo sell the exact same bag for a third of the price http://www.ewetsuits.com/acatalog/drybag-daypack.html?gclid=CNvThbyH9swCFbQV0wodNBcOcA

The Lomo looks great value for money. Why do you loathe your Polaris Aquanought?

The rubber cover on the front zip peeled after about a week and the area around the zip began to fray - just not great quality for a £70rrp bag. Polaris just said 'talk to the company you bought it from' which was a store in eBay which was pretty annoying to deal with. The Lomo bag is exactly the same but with different label, as far as I can tell.

Got an Alpkit here and it's been brilliant so far;definitely waterproof,light and really comfy on the bike

It is only a simple open bag but you could use another padded case for the laptop in it;I use another Alpkit bag insude to keep all the loose stuff(phone,glasses,pump,etc) together.

I should add that I don't actually own an Alpkit bag - I just thought they might be the kind of thing the OP was looking for.
