U.S. Army Canteen

The M1 NBC cap is a specialized closure designed to allow for drinking while wearing a gas mask, featuring a threaded port that connects to a mask's drinking tube. For standard outdoor use, it functions as a secure, leak-proof seal, though it is slightly more complex to operate than a standard screw cap.

These canteens are manufactured to military specifications using durable, food-grade plastic. While they are designed for rugged field use, they are older military-standard designs and not explicitly marketed as BPA-free, so users concerned about plastic leaching may prefer a stainless steel alternative.

Yes, this is a standard 1-quart USGI canteen, meaning it is designed to fit perfectly into all standard-issue military canteen pouches and most aftermarket tactical gear designed for 1-quart vessels.

No, this canteen is made of plastic and will melt if exposed to direct heat or open flames. If you need to boil water in the field, you should transfer the water to a metal canteen cup or a dedicated metal pot.

Like most plastic hydration vessels, this canteen can retain odors if sugary or flavored drinks are left inside for extended periods. We recommend rinsing it thoroughly after each use and sticking to water to keep the interior fresh.
