Cnoc Hydriam 750ml Collapsible Flask, 42mm - Blue

Ultralight hydration at your fingertips

Looking for a spacious yet discreet way to carry water while running, trekking, or fastpacking? The Cnoc Hydriam 750ml Flask, 42mm - Blue is one of the lightest models in the brand's range, designed for the most demanding ultralight gear enthusiasts. Soft, durable, and highly functional – it is always ready to provide you with instant hydration.

A perfect fit for your gear

The design of the Hydriam softflask stands out with its modern, tapered profile. This feature is a key advantage that makes it significantly easier to smoothly slide the filled bottle into the snug pockets of running vests or the side compartments of a backpack. The benefit for you is maximum comfort while on the move and fluid access to your drink, without stopping or unnecessarily breaking your pace on the trail.

Instant filtering straight from the stream

This model is equipped with a sturdy neck featuring a wide 42mm thread. The advantage of this common standard is full, immediate compatibility with fast hiking filters, such as the reliable Katadyn BeFree. The ability to screw a filter on directly provides a powerful benefit – it allows you to safely refill and drink water from sources found on the trail, so you can drastically reduce the weight of fluids carried on your back.

Thoughtful details for full control

A clear volume scale is printed on the back of the bottle, and the cap itself is securely connected to the body using a strong tether. The advantages of these seemingly small additions are precise water measurement and the total elimination of the risk of losing the cap in moss or tall grass. This translates into a concrete benefit: stress-free cooking of hot meals at camp and complete peace of mind even at the end of an exhausting day on the trail.

Compactness that makes a huge difference

The main reservoir is made of certified, flexible TPU material. Thanks to this, the large 750ml capacity bottle weighs only 36 grams and, when completely emptied, can be quickly rolled up into a tiny bundle. The advantage of this solution is maximum transport space savings. Your benefit? A noticeably lighter step and optimized space in your backpack for other essential emergency gear or clothing.
