REI Garage offers the MSR Alpine 33.8-oz. Stainless Steel Water Bottle in Brushed Stainless for $16.73. Choose in-store pickup to dodge the $5.99 shipping fee. That's $24 under the lowest shipped price we could find today, although we saw it in another color for $2 less in March. It features BPA-free 18/8 stainless steel construction, a tri-lobe design, quick-connect adapter lid for integration with all MSR water filters (sold separately), and small sipping port.
