Nalgene Ultralite Narrow Mouth 4oz BPA-Free HDPE Round Storage Bottle

Four ounces of leakproof, ultralight HDPE storage — the workhorse of the backcountry kit.

The Nalgene Ultralite 4oz Narrow Mouth Round Bottle is the right size for most trail-side liquids — enough capacity for a multi-day supply of camp soap, fuel treatment, sunscreen, or cooking oil without the bulk. Made from durable, BPA-free HDPE, it's shatter-resistant, leakproof, and built for real outdoor use.

Why It Works

HDPE is chemical-resistant and won't absorb odors or flavors, making it safe for food-grade liquids and camp chemicals alike. The narrow mouth gives you controlled dispensing. At 4oz, it's the sweet spot between the micro bottles and larger containers for most backcountry applications.

Ideal For

Backpackers, thru-hikers, hunters, anglers, overlanders, and anyone decanting liquids into trail-ready containers for multi-day trips.
