Subject: RE: Profile designs areo drink: messy!!!I don't use the yellow thing. Just the foam rubber gasket/disk think under the cap. I never get splashed...BUT I used to get soaked with back spray after taking a drink. So I got a Camelback bitevalve and jammed it over the end of the straw. It took a little work the first time, but it does go on. Since installing that, not a single drop of spray on me. |
