Torrent Stretch Fabric

Designed for aerodynamic performance, the Pro Fit Light Rain Jacket has a smooth face to make you look good while cutting through rain efficiently. The waterproof Torrent Stretch fabric is a 3-layer woven composite with an impressive 2-layer DWR laminate that does a great job at retaining your body heat while warding off the elements.

Some severe oomph augments the Torrent in the form of 37.5 Technology’s woven Cocona particles, which are the stuff that makes this top-of-the-range garment as breathable as it is water resistant. The little spies are in for a treat, too, with a long drop tail and articulated sleeves that tick all the boxes.

The best part is that the Torrent is also lightweight and packable. It might not be as aesthetically pleasing as the Gore-Tex Idro jacket, but the Pro Fit Light is an impressive piece of kit and is well worth the premium you’ll have to pay.
