Terra Fieldworks Ultralite Nalgene

The only Nalgene we run in the backcountry. The Ultralite (HDPE) 32oz Nalgene is the perfect balance of weight and strength. At only 3.5oz, HDPE is ~45% lighter than your typical Nalgene Tritan bottles you'll see your crunchy coworker carrying around the office. HDPE has a slight flex to it, so if you happen to slam it against a rock, you won't have to worry about it shattering.
