The opinion of Aventure Nordique

The HydriamX Collapsible Flask 42mm is a flexible water bottle with a tapered design that slips easily into the pockets of a trail running jacket or rucksack. Designed by the young and still confidential brand Cnoc. It offers an unbeatable weight/compactness/volume ratio!


This version with a large 42-mm threaded cap is compatible with 42-mm water filters from Katadyn Befree, LifeStraw (Peak Series Collapsible Squeeze), etc.


Lightweight and compact, the HydriamX Collapsible Flask 42mm weighs 31.2 grams and holds half a litre.


This X version has thicker materials. This more robust flask can withstand temperatures from -17 to 100°C. This container can therefore hold liquids boiled at 100°C, but Cnoc recommends a lower temperature (80°C) to avoid burns and material fatigue.

Points to remember

The HydriamX Collapsible Flask 42mm is a reliable, practical water bottle that is compatible with the Katadyn (Befree) and LifeStraw (Peak Series Collapsible Squeeze) water filters. The X version is more resistant and durable.
