Nalgene Blue Loop-Top Replacement Lid/Cap for 16/32oz Narrow Mouth Bottle

Lost your cap? Don't replace the bottle — just replace the lid.

This genuine Nalgene Blue Loop-Top Replacement Lid fits all 16oz and 32oz Nalgene Narrow Mouth bottles, including Oasis models. The loop-top design keeps the cap attached to your bottle so it won't get lost again, and the leakproof seal is as reliable as the original.

Why It Works

A lost cap shouldn't mean a new bottle. This is the exact same lid that ships with Nalgene's narrow mouth bottles — same fit, same seal, same durability. The loop keeps it tethered so it stays with the bottle on the trail, at the gym, or in your bag.

Ideal For

Anyone replacing a lost or damaged cap on a Nalgene 16oz or 32oz Narrow Mouth bottle, or stocking a spare for long trips.
