Better to protect the contents with poly bags or similar.

There are sprays, such as those from Nikwax. Although that only really makes the nylon showerproof,
if you want to waterproof nylon it needs a coating of some kind such as PU, which need to be done
when the nylon is made.

Rucksac seams often dont lend themselves to easy sealing, you could seal as you might with a tent
seam, but a lot of work.

This is why most people just use a stout polythene rucsac liner, easy to replace when it
starts leaking.

There are nylon bags that are waterproof (they are a bit like tall stuffsacs), these are
designed for primarily for watersports and are waterproof to the extent that they will withstand
immersion in water.

Not really: the fabric on most sacks is typically waterproof but the seams aren't, so they typically
leak through the seams. If the actual PU coating on the fabric has all rubbed off you might improve
general leakage through the fabric with something like Nikwax TX10, but I very much doubt that will
render it "waterproof".

A pack cover will keep the rain off it to start with (though make access fiddlier) and internal
liners will keep contents dry in any case. Either is probably better than trying to render your
basic pack waterproof.

There is no such animal as a waterproof rucksack. Either invest in a rucksack cover ot get one of
the polyethene liners - both work well and keep stuff dry. Pack covers are better when you put yer
pack on the ground and it's raining IMHO

After mine started leaking at a seam I started using a liner. It wasn't much just enough to make a
pair of trousers damp. I also tried proofing but it was only partially successful. I tried wax both
spray and manual application. Nothing wrong with the quality of the sac. It was loaned out for the
umpteenth time and got very badly pulled. Just enough to ease the needle holes a bit wider. I still
use it and lend it. No problems now.

I think that you will find that it breaks some sort of law or BS Standard to have a waterproof
rucksack :-(

'Euro Norm' now, if you please <g>. Seriously though, I can see why equipment manufacturers shy away
from using the very strong word 'waterproof', but it would be helpful if there was some universally
understood set of terms to describe degrees of resistance to water.

Packs seem to be like boots. No matter what you try, water is eventually going to get in if the
conditions are bad enough. Some good suggestions with bag liners and pack covers (although I no
longer use pack covers either). Go to your local veterinarian (sic?) and ask if you can buy a couple
of their 'doggie' bags (what they place dead animals in for disposal). I have found these to be
extremely strong and durable, and you can usually get a couple of sizes, say smaller one for
sleeping stuff / spare clothing, and a larger one if wanted for general gear. I usually just screw
the bag top up and push it down one side. Cheers.

Just to follow up on waterproof bags, I strongly recommend Mountain Equipment's new Pneumo range,
which combines stuff sack with dry bag. I have had one for a few months now and it's been excellent.

Nothing ever got wet inside my Berghaus Cyclops Roc, which I used from the late eighties onward and
which is still in good condition, very hardwearing. Made of very tough cordura, there was also some
sort of lining inside, presumably waterproof, but that's long since worn away. Still doesn't leak
though, but I've always wrapped everything in stuff sacs and plastic bags anyway.

Mine is essentially the same but without the big pockets and it's only 70 litres.

You can't break unenforceable laws!

I doubt that.

My Macpac never let any water in for the first 10 years of its life. The last couple of years,
things have started to get wet in really heavy rain.

Vau De, Ortlieb and Craghoppers make waterproof packs. Ortliebs with a rolltop will take submersion
under pressure. But of course, they're not waterproof if you open the top in a downpour, or put in a
soggy tent fly in the morning...

I can't say that's ever happened with my Berghaus Cyclops Roc. Damn good sack.

What size do you ask for for a 45 litre sack...a Jack Russell or a Labrador?

Shops that cater to paddlers often have a good selection of dry bags. Ortlieb, Vau De and Seal Line
(from Cascade, the Thermarest folk) are all pretty good.

Unfortunately the back just didn't fit me that well so not much use to me, but the nice thing
IMHO about the old Cyclops was it wasn't covered in whistles and bells just for the sake of
them. Whistles and bells generally mean extra seaming, and extra seams means leaks. Rucksacks
(at least decent ones) are typically made of waterproof cloth, but the seams aren't taped so
water can get in there.
