Nothing ruins the well earned panoramic view from your own local Cima Coppi like the vertiginous effects of dehydration, so stay on top of your thirst when you're hitting the top of the KOMs with Twin Six's Vertigo Bottle. Don't let the graphical treatment hypnotize you into thinking the Vertigo is all style and no substance, though Twin Six opts for the much loved Purist bottle to use as the canvas for its design. The bottle's interior is finished with a 5 nanometer thick application of silicon dioxide, an inert compound that's dishwasher and microwave safe. It prevents plasticizers from leeching into the bottle's contents and eliminates that accumulation of mysterious funk that tends to make bottles one season affairs. The soft, rubbery mouth won't ding your teeth when you pull it open, and the MoFlo design gives a substantial dose of refreshment when you need it.
