Product description of Montane Cetus Lite jacket

Description summary

Breathe easy on the trail with the MONTANE Cetus Lite jacket. Engineered for high-intensity adventures, this PFC-free waterproof shell excels at moving moisture away from your body, thanks to its exceptionally breathable (RET 5) PETRICHOR TECHNOLOGY™. The 3-layer, 100% recycled nylon fabric provides durable 20K waterproof protection. Featuring an adjustable hood, YKK Aquaguard zips, and articulated sleeves, it´s built for comfortable, efficient movement when you´re working your hardest in the mountains

Built to breathe out The Cetus Lite delivers next-generation PFC/PFAS-free, 100% waterproof performance that’s exceptionally breathable. Built around Montane’s new PETRICHOR TECHNOLOGY™, the lightweight, durable 3-layer fabric has a 20K hydrostatic head with a breathability rating of RET 5. A 100% recycled nylon face fabric sits over a windproof, non-porous hydrophilic membrane, which physically transports moisture away from the body, through the microclimate inside the jacket and into the air outside. This is ideal for dynamic outdoor missions with high-intensity output, because the harder you work, the harder this membrane works to deliver comfort, and conserve energy in the mountains.


Features:

- Fully Adjustable Hood: For a precision fit and unhindered vision
- YKK Aquaguard Hand Pockets: Storage sealed against the weather
- Offset Seams: Improve construction, durability and comfort
- Fully Adjustable Hem: Optimises the fit to keep the weather at bay
- Articulated Sleeves: For unrestricted movement with adjustable hook and loop fastenings
- Laminated Technology: Peak, hem and cuff tabs laminated to reduce seams and improve durability
- YKK Aquaguard Front Zip: Weather-proofed zip for a versatile fit
- PFC-Free DWR: Coating on face fabric applied to bead and shed moisture
- Suitable for: Hiking, Walking, Trekking, Trail Running, Fastpacking
- Fit: Regular - Standard fit for core outdoor activities


Specifications:

- Materials: Shell Face: 100% nylon (recycled), Shell backer: 100% nylon
- Weight: 295 g


Technology:

Petrichor Technology™ 3l. High-Performance Breathability:
- Montane’s PETRICHOR 3-layer technology delivers waterproof (20k Hydrostatic Head), exceptionally breathable performance to the Cetus Lite Jacket. It scores a RET rating of less than 5, which means it is ideally suited for high-output activities in the outdoors, where it will remain breathable to keep you dry inside and out. This is achieved through the windproof, non-porous hydrophilic membrane that transports water vapour and moisture away from the body, an effect that increases in strength as you work harder. The 3-layer construction sandwiches the waterproof membrane between a 100% recycled, 21D Ripstop nylon face fabric and the lining, for improved durability and next-to-skin comfort.

Offset Seams. Lightweight Construction:
- The Cetus Lite Jacket has been built using offset seams. Instead of lining different seams up with each other where they meet on the garment, offsetting them enables us reduces the number of seams needed during construction, as well as its weight, and boosts the lifespan of the garment. This is one of the reasons why the more durable 3-layer construction remains lightweight. Seams are further reduced by having the peak, hem and cuff tabs laminated, a process that also increases durability in those areas.
