Nalgene has been the gold standard in reusable water bottles for decades — the wide-mouth design opens big enough for ice cubes and easy cleaning, and the attached loop lid means the cap doesn’t get lost or dropped on a trail. The Tritan copolyester construction is BPA-free, virtually indestructible, and resists odors and staining even after years of daily use.
The 48-ounce Sustain holds a full day’s hydration in a single fill and uses Tritan Renew, a material made partly from recycled content. The wide mouth fits standard filters and ice, and the graduations let you track intake through the day. It’s oversized without feeling awkward — room for long hikes, long commutes, and long shifts.
Nalgene has manufactured laboratory and outdoor bottles in Rochester, New York since 1949. Originally a scientific-grade container company, Nalgene became the default backpacking bottle after employees started taking them on hiking trips in the 1970s. Every bottle is still molded, assembled, and printed in New York State.
