More than a liter, less than a hassle — the 48oz Silo for big hydration days and eco-conscious adventurers.
The Nalgene Wide Mouth Sustain 48oz Silo bottle in Slate Blue with Black Cap gives you 1.5 liters of capacity in Nalgene's tall Silo form factor — perfect for long days on the trail, at the gym, or at the desk when you don't want to refill constantly. Made from Tritan Renew resin derived from 50% recycled plastic, it delivers the same legendary Nalgene durability with a reduced environmental footprint.
The 48oz Silo hits the sweet spot between the standard 32oz and the oversized 64oz — enough capacity for a full morning of activity without the bulk of a half-gallon jug. Sustain Tritan performs identically to standard Tritan but is made with 50% recycled plastic waste.
Ideal For
Hikers, gym-goers, office workers, and eco-conscious buyers who want high-capacity, sustainable hydration without constant refills.
