Nalgene | Sustain 16oz (500ml) Wide Mouth Bottle

Compact Hydration Built for Streamlined Trail Flow

When you are heading out for a quick, fast-paced training loop on local singletrack or looking to balance your gear payload on an self-supported weekend fastpack, a massive one-liter bottle can feel like overkill. The Nalgene Sustain 16oz (500ml) Wide Mouth Bottle packs all the legendary, shatterproof reliability of its larger counterpart into a compact, low-profile footprint. Designed to celebrate the simple joy of quiet afternoons in the woods, this space-efficient bottle slides effortlessly into compact pack pockets, waist belts, or travel kits, ensuring you stay perfectly hydrated without carrying unnecessary bulk or shifting weight.

Eco-Conscious Durability with Next-Gen Recycled Resin

Protecting the vibrant, moss-covered trails we love means choosing gear that tethers performance to sustainability. The Sustain series is mindfully crafted from Tritan Renew copolyester, a next-generation material powered by 50% certified recycled plastic waste. This shift drastically minimizes environmental impact while preserving the iconic impact resistance that made Nalgene a backcountry standard. Whether it slips from your grip onto a granite ledge or gets rattled around with climbing gear, it won't crack, puncture, or shatter. Entirely free of BPA, BPS, and phthalates, it leaves your water tasting crisp, clean, and completely free of plastic aftertastes.

Flawless Field Performance and Total Leakproof Security

Out in the woods, a leaky bottle can instantly ruin your day by soaking your dry layers or electronics. Engineered with continuous, straight-shouldered, semi-buttressed threads, the heavy-duty cap locks down to form an absolute, airtight seal you can trust inside any pack payload. The 53mm wide-mouth opening provides excellent real-world utility—it easily accommodates ice cubes for hot summer miles, simplifies post-run cleanup, and links up cleanly with specialized water filtration adapters for quick, hassle-free refills at wilderness streams.
