Nalgene 48oz W/M Silo Sustain, Gray w/ Blue Cap (2nd)

The original. The trailblazer. The Sir Edmund of water bottles. If you’re looking for a water bottle that will keep you well hydrated, hold up against bangs, bumps, and drops, and not leak a single drop ever, then the iconic 32-ounce wide mouth is your water bottle. There’s a reason why we haven’t changed its design in decades—because it works (extremely well).
