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 is our PFC/PFAS-free high-performance waterproof jacket built for outstanding breathability (RET 5) using Montane’s new PETRICHOR TECHNOLOGY™ . The 100% recycled nylon outer has a PFC-Free DWR coating and 3-layer durability. This jacket’s 100% waterproof, hydrophilic membrane excels in transporting water vapour and moisture away from your body and out into the air during high-intensity outdoor adventures, while keeping out the wind and rain (20K hydrostatic head). The harder you work, the harder it works to ensure comfortable, efficient movement in the mountains.

- Fully Adjustable Hem: To prevent the weather getting in
- Laminated Technology: Peak, hemand cuff tabs laminated to reduce seamsand improve durability

- Weight: 320 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 5 rating, 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 by 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, enabled by the 3-layer construction. This 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 to where they meet on the garment, offsetting them enables us reduces the number of seams needed during construction, along with its weight, while extending the lifespan of the jacket. 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 strengthens those areas.
