Nalgene

Nalgene makes durable water bottles that work in most situations - at work, in your bag, at the gym or out in nature. The bottles are lightweight, leak-proof and easy to wash. They come in several sizes and with both wide and narrow openings depending on your preference.

The material is BPA/BPS free and largely recycled. These are bottles that will last a long time and withstand tough use without any problems. Nalgene has been making bottles for many years and is one of the most well-known names in its category.
