Nalgene Sustain 32 oz. Wide-Mouth Water Bottle (Tritan, Leak-Proof)

The Nalgene Sustain 32 oz. Wide Mouth Water Bottle is a classic reusable water bottle made from durable Tritan plastic (BPA/BPS/phthalate-free). The wide-mouth design simplifies filling, ice-cube addition, and cleaning—a hallmark of Nalgene's design philosophy. This version is single-wall (no insulation), so it won't keep drinks hot or cold for extended hours; it's best for room-temperature hydration or shorter outings.

Key features:

• Temperature range: −40 to 212°F (suitable for hot and cold beverages)
• Completely leak-proof seal when closed
• Dishwasher-safe (top rack)
• Lightweight (~0.04 lb) and compact (3.15" W × 7.87" H)
• No insulation—fastest warm-up in the sun

Nalgene bottles are trusted for their indestructible build, iconic branding, and affordability. The Sustain line uses recycled plastic, appealing to eco-conscious buyers. Ideal for office, gym, hiking, and everyday carry where durability and leak-proofness matter more than temperature retention. Not a contender for all-day cold retention against insulated rivals.
