Can't find anyone that makes these surely a waterproof backpack is a no brainer! And I don't want one with those stupid rain covers that don't fit very well. Anyone know of any?
No. Use this inside, cost 5p

^ That doesn't keep the pack dry though.
Ortlieb make a courier backpack - roll top...
Would like an mtb specific one
Gourdon with a bladder down the pad pocket works for me when i want to carry more than my mule will handle.
My alpkit gourdon has a compartment for a hydration pack. Never used it though as is just my commuter pack.
Deuter speedlite. Different sizes available and waterproof.
Wingnut
Why do you need to keep the pack dry? Surely even 'tarpaulin' material packs get wet & muddy on outside - the only difference is wetting out.
Use gear proof from Nikwax, protect what you need to inside in plastic bags.
Evoc rain cover fits perfectly, keeps dry
Gourdon with bladder is the only sanely priced option not involving extra covers or liners I think.
I just use a hydrapak and use zip locks for anything that needs to stay dry though. Will be looking at Ospreys when I need a new pack ad I like the Axis I picked up for commuting very much...
Why do you need to keep the pack dry?
Because that is what the OP was asking. Not whether it is a good idea or not.
I use a cheap drybag from Wilkinsons inside my rucksacks
as per Matt_OutandAbout
It worked today. Wet outer, with dry inner 🙂 Proper Job!

Not tried one but look good and for £25 I'm very tempted...
There's that hugely expensive Acre one. Pretty sure Dakine have (had) something too.
Kriega - simply the best there is.
Unless you go for a rolltop drybag like the Alpkit Gourdon best option is to pack your stuff in multiple drybags inside a waterproof liner.
Doffs cap at red thunder.
Wingnut mine's ace
Turn it inside out.
As above. Wingnut.
[*]Alpkit Gourdon, it is MTB specific, if you want it to be.

Just take the elastic off, it gets stuck in trees.

^^ this
alpkit gourdon.
simple and therefore brilliant.
fits nicer them my 'proper' evoc bag.
no internal compartments for the OCD part of my brain which took some coming to terms with but now i`m over it all is well.
when its really minging (which seems to be everytime i have time to ride atm) i find bag covers still allow the contents to get wet through the non waterproof bit on yer back.
Genius all that - take a pack twice the price of a Gourdon and use a plastic bag to make it less waterproof than a Gourdon 🙂
Gourdons are ace - one of my favourite mtb products of all time.
Wing nut is pretty good. Ah Proper Job! Always pay the Glastonbury store a visit when seeing my Dad.
They're all waterproof. Otherwise they would let all the water out.
So, what bladder for a Gourdon, then?
Most Deuter rucksacks have a pull out cover for when the torrential rain starts...
My old crossair was great until I ripped it after 4 years of use.
