It's been an hour since your last sip of water. You're parched. Luckily you have a 1L Nalgene water bottle on your backpack. You take a gulp. It's refreshing. So refreshing, you drop your bottle on some rocks. No worries, the Nalgene doesn't mind.
The seemingly indestructible 1 liter Nalgene water bottle is a staple for nearly any activity you can think of. Backpacking? You bet. Mountaineering? Obviously. Bikepacking? That too. Commuting to work? 100%.
