Polar 24 oz bottle, Camelbak
podium chill cover. The Polar comes in clear, and with the Camelbak cover there is no nipple to pull out and push back in - just squeeze to drink. So far, the Polar bottles are the only ones that the podium chill covers fit on. The podium chill is insulated, so it only holds 21 oz, while the polar holds 24 oz.
