Title: Little annoying to fill to 3L......
Review: Filling the first liter? Pour it in. Force of the fluid pushes the back of the bladder out of the way and there's no issue.Filling the second liter? Requires a bit more coordination, but still pretty easy.Third liter though? That requires grabbing the handle in one hand, holding the bladder effectively horizontal, shoving the "retained" cap out of the way, and then pouring in the 3rd liter..... when you're finished, disposing of your container, and then tightening down the cap, because 3L essentially comes to the lip of the fill hole.Once filled though? Works quite well.
Is the review positive or negative?
