Cnoc HydriamX 500ml Collapsible Flask, 28mm - Green

The extreme durability and lightness you're looking for

Are you looking for a reliable softflask that will perform in the toughest trail conditions, during mountain runs or fastpacking expeditions? The Cnoc HydriamX 500ml Flask, 28mm - Green is a flexible, collapsible reusable bottle made from reinforced, thicker TPU (used in the heavy-duty VectoX series). It is an ultra-durable yet ultralight container for enthusiasts of top-class gear.

Safe transport of hot liquids

Unlike standard softflasks, the HydriamX model features an exceptionally wide operating temperature range – from -17°C to as high as 100°C. This unique feature allows for the safe pouring of boiling water and hot drinks (the recommended usage temperature is up to 80°C to avoid burns and material fatigue). The advantage of this design is its versatility: the bottle can serve as a warmer tucked into a sleeping bag on a cold night or a container for a warming drink after hitting the slopes. The benefit for you is year-round functionality and the certainty that the container will not deform or be damaged.

Ergonomic shape for running vests

Cnoc engineers used a tapered design, thanks to which the filled softflask has a streamlined shape. The advantage of this construction is the lack of resistance when efficiently sliding the bottle into and out of backpack side pockets or running vest compartments. This means the benefit for you is convenient and instant access to liquids while on the move, without stopping or wrestling with your gear.

Universal filtration directly on the trail

The softflask is equipped with a universal 28mm thread – exactly the same as used in the iconic Cnoc Vecto. The advantage of this standard is immediate, direct compatibility with popular hiking filters, such as Sawyer (Squeeze, Mini, Micro), Platypus QuickDraw, or HydroBlu Versa Flow. You get a powerful benefit: you can filter and drink clean water directly from a stream during long runs, saving time and drastically reducing the weight of the gear you carry.

Refined in every detail

The bottle is equipped with a cap attached to a flexible strap (tethered cap) and a volume scale printed on the back. The advantages of these solutions are precise water measurement during camp cooking or preparing isotonic drinks and no risk of dropping the cap in the grass. Due to the porous structure of the TPU material, it is recommended to thoroughly wash and air out the bottle before first use. The benefit is complete peace of mind, hygiene, and reliability on every route.
