What is the Cetus Jacket?
It's a highly breathable, comfortable and packable waterproof shell that does things a little differently than traditional waterproof jackets. It utilises Montane's innovative PFC-Free Petrichor waterproof technology for high-performance weather protection and breathability for various outdoor activities across the seasons.
What is it made from?
The Cetus Jacket features Montane's innovative Petrichor 3L waterproof technology. Petrichor delivers exceptional breathability and waterproof protection for all manner of wet-weather adventures. It scores a waterproof hydrostatic head rating of 20,000mm and a breathability rating of RET 7, meaning it excels in various activities in adverse conditions, where it will remain breathable to keep you dry inside and out.
Montane's Petrichor uses 100% recycled nylon fabrics in a 3-layer sandwich construction to deliver a lightweight and comfortable shell jacket that's noticeably quieter to wear. The 30-denier nano ripstop face fabric provides lightweight durability, whilst the 20-denier solution-dyed tricot lining offers efficient moisture transportation and next-to-skin comfort. Sandwiched in the middle of these lightweight fabrics is the super-thin Petrichor membrane, which is both waterproof and windproof. All fabrics used to construct the Cetus are free from harmful PFC/PFAS chemicals and are also Oeko-Tex® and Bluesign® approved for extra reassurance that the jacket was created responsibly.
Montane's Petrichor membrane does things a little differently from traditional waterproof jackets. For those unfamiliar with waterproof clothing technology, conventional waterproofs rely on hydrophobic membranes with thousands of tiny, microscopic holes in them and a difference in either temperature or pressure inside the jacket to pull water vapour through the membrane to allow it to escape. Though widely used, this technology can be hindered if the DWR on the face fabric of your jacket fails and 'wets out' or the tiny holes become blocked over time by dirt and skin oils from sweat, resulting in a very clammy, gross-feeling waterproof jacket that might feel as if it's leaking.
Petrichor, in contrast, is a completely solid non-porous hydrophilic membrane that actively breathes to physically transport moisture away from the body and damp layers, pulling it out into the air where it can escape. It utilises channels within the material to pull moisture through the membrane to continuously manage your microclimate, keeping you comfortably dry all day long, an effect that increases in strength as you work harder - the tougher the trail gets, the more breathable the jacket becomes. This innovative design delivers supercharged breathability and allows this super-thin solid membrane to be not only waterproof but windproof too. Neat right?
The jacket is finished with a PFC-free DWR (durable water repellent) to encourage water, dirt and snow to bead off the material, further enhancing the jacket's protective capabilities.
For those of you who are wondering, PFAS/PFC's are also known as 'forever chemicals' because they stay permanently in the environment, bioaccumulate in animals and cause lasting damage to our ecosystems. Due to their harmful nature, many companies are working to eliminate their use in products and manufacturing processes. Montane's Petrichor technology is at the forefront of responsible, highly breathable waterproof clothing and is helping pave the way towards a PFC/PFAS chemical-free future.
What are its features?
Starting from the top, a fully adjustable hood delivers protection from the elements, while a laminated peak helps keep rain and snow away from the face. The hood can be cinched right in close to the face for maximum protection in adverse weather without hindering your line of vision. At the front, a YKK centre front zip helps keep rain and wind from reaching you inside the jacket.
For storage, you'll find two YKK aqua guard zipped hand pockets and a zipped internal chest pocket. The hand pockets are ideal for keeping items such as energy gels, trail snacks, a GPS device and small guidebooks close to hand. Whilst the internal pocket provides secure storage for more valuable items such as a mobile phone and keys.
The Cetus features Montane's regular fit, which offers enough wiggle room for layers underneath without hindering movement whilst still sitting close enough to the body for optimal thermal retention. Articulated sleeves offer a natural range of movement for various activities, whilst grown-on adjustable cuffs allow you to achieve a snug fit, even around gloves.
A fully adjustable bottom hem helps stop cold wind and rain from blowing up inside the jacket on exposed routes. Montane has used a clever offset seam construction throughout the jacket to enhance comfort levels and provide added durability across the seams.
Finishing details such as a laminated peak, hems and cuff tabs add durability to key areas whilst still keeping the jacket's overall weight and pack size to a minimum.
