Nalgene

When you need greater capacity, the Nalgene Silo is the ticket. It is leakproof and easily slides into standard packs and backpack side pockets. It is very durable and has the standard 63mm Loop-Top cap. The neck configuration works with most major water purifiers and filters.

Nalgene Sustain bottles are made with material derived from 50% plastic waste. Each bottle is created from resin powered by next generation recycling technology that transforms plastic destined for landfills into high-performance bottles.

Made in the USA.

Nalgene is in the process of transitioning logos, which means your bottle may or may not have the Sustain logo. Both types are the Sustain bottle.
