Hello. I purchased a couple of Nalgene hardsided “UL” bottles for a guided mountaineering trip where we weren’t allowed to use bladders or soft bottles. I normally use evernew bags in conjunction with a Sawyer, but I’m now moving to a Steripen where I need a wide bottle. I actually like the hardsided Nalgene very much compared to the Nalgene collapsible canteen. I know this is BPL, but does anyone carry these despite the 50 g penalty?
