PAST Outdoors Originals Titanium Canteen Cup 1 Litre Nalgene

Exactly what's required to fit onto a Nalgene 1 or 1.5 Litre. Has a vented lid and fold out handles. Excellent quality. Not cheap, but quality isn't. Happily recommend this item.

Great size for heating water & cooking my morning oats. Also a bonus that a Nalgene/similar 1L bottle fits inside it, my different branded bottle fits snugly. Paired perfectly with my Soto Windmaster stove. Absolutely love having it in my hiking/camping kit.

Lightweight and functional, this titanium mug performs as expected in terms of basic use. However, I specifically chose it because it was advertised to fit snugly around a 1L Nalgene bottle—which it does not. It sits loosely and often slips off when removing it from my bag. Given the price point, I expected a secure, precise fit. This was a key selling point and ultimately a disappointment.

Great mug that sits flush with the nalgene (great for reducing space in the pack) and fits drip filter coffee bags. Being able to double as a smaller pot with the lid is a bonus!

This is a great mug.
Perfect example of one thing that does a few things. Cook a meal in it, boil water in it, drink a coffee out of it.
It’s light and strong.
The handles are good and don’t carry the heat from the stove for very long.
Side note, it’s not too large to use with an Aeropress.
