Gear research at the Dawson house goes on despite Dad’s absence (he’s out on a hut trip for a few days). During a recent shopping trip, I found a Nalgene Cantene. It has a wide mouth, a bottom gusset for standing upright, is available in 16, 32, 48 and 96 oz. sizes and it collapses when empty. Best of all, it’s a whopping 4.4 ounces lighter than my regular Nalgene bottle. I plan to use it on my next trip and ace everyone out with the lightest pack. See you at the top Dad!
