Drinking Bladder

[Wolf_Larson]

Ill do the bottle thing n all.

I have a Sigg too but I like that I can drink from the bladder without having to dig a bottle out of the side pockets of the rucksack (which I can never reach without taking it off)

just get your mate to get it out for ya, that way you dont have to stop at all! you can get a conversion thing to give a sigg a bladder-esque drinking tube but i dunno how good they are.
