Nalgene Tritan Bottle Wide Mouth (1.4L)
Widely used and loved, Nalgene Tritan bottles are leak proof (and no O-ring!), BPA free, dishwasher safe, ultra durable and resistant to picking up taste or odour. They can withstand temperatures from -40°C to 100°C. It's hard to find an outdoor adventurer that doesn't have at least one.
