A 2L reservoir full of water weighs approximately 2.2kg (2kg water + 200g bladder). A 3L system weighs about 3.3kg. This is significant and does affect balance, especially when the bladder is full at the start of the day. Position the reservoir against your back (which is standard) for the best center of gravity. As you drink and the bladder empties, the weight decreases and the pack becomes more manageable. Use compression straps to keep the load tight as the bladder shrinks.
