Hi,
I am after a hydration bladder and hose which leaves the least amount of residual plastic taste. I've tried two, a Karrimor one and a Nathan one, and both tasted pretty bad, especially the Nathan one. Note I'm not talking about any odor which develops due to not cleaning, etc. This is a taste you feel straight away new from the box (and stays even after washing out with soap a few times).
I think the problem usually lies with the mouth-piece itself rather than the bladder. I'm completely fine with the taste from platypus bottles, but haven't tried their hydration system. Are all mouth-pieces always bite-valves, or are there other systems too? (screw top?) Might be less convenient, but I have a feeling my problem is with this soft material on the valve that you bite into.
No need for it to be ultralight.
Thanks!
Greg
