How does stainless steel compare to aluminum in weight?
Pura Stainless bottles are comparable to similarly sized aluminum and stainless bottles. That said, a full plastic, aluminum or stainless bottle weigh virtually the same amount because water is heavy... and what is the point of carrying an empty bottle?

| 1.2L/1.5L | 9.3oz | 9.5oz |
| 0.8L/1.0L | 8.1oz | 5.0oz |
