I bought one of these on ebay some time ago, and has served me well on several backpacking trips.

I would now however like to replace it with something more modern, but not sure how big a sac to buy. The berghaus is about the right size, but how big is it? I can't find any reference to this rucsac on the web at all. I suspect its about 70 litres ish, but would be grateful if someone could tell me for sure, it would help in choosing my new sac.

Cheers Steve

Err I think the cyclops 2 is about 90ltr's

Is it a large green one, with detachable side pockets?

No its not the military one. It has no side pockets, and is a kind of turquoise colour with red back.

Have a look at:

this could be double dutch to me but i reckon 70 litres

According to Altavista Babel fish, this is what it says.

The back pocket...

But to start at the main point. My back pocket is kicked off Berghaus
Cyclops II Aztec. There, according to me, litertje enter or 70. I have
got him of my aunt, because he became large for its old back. Thank
you, however, Jacquelline.

So Rugzak translate to back pocket - However I agree it referes to 70 litres.

Thank Hamish.
