Nick’s Design Notes: I wanted to create a lightweight waterproof that could be a utility outer shell, any time of year. The piece of kit I know is always there when it's needed. I couldn't see examples with clean lines & plenty of pockets. That means street style & wilderness practicality. A jacket I can go out around London in, not just a soggy mountain. Oh, and a banging hood that fits, and stays! Here you go. Enjoy!

What don't packable waterproofs have? Enough pockets. What should they look like? Not like bin bags. Can they we do better than the Big Brands? Well, not wanting to be immodest, but, yes...

At the core of the 4 Seasons Waterproof is a fully sealed, soft, matt-textured 3-layer stretch nylon fabric created for us in North Eastern Italy. Rated 20,000 waterproof & breathable, it has supreme technical performance, but doesn't have that shiny plastic bin bag quality that plagues waterproofs. The inner layer is soft and does not stick to your skin. With a high proportion of elastane, it moves freely, for impromtu break-dancing or bouldering.

The hood is special. A 6-panel construction with a proper storm-peak allows exact shaping around the head, once the front and rear shockcord adjusters are adjusted. This gives the hallowed result of full peripheral vision, with face coverage and a close fit, without looking like Kenny from South Park. It is our pride & joy.

There are concealed, unique vents under the arms, like a shark's gills, that allow warm, moist air out. We have added large cargo pockets and a fully waterproof chest pocket fit for a next-gen phone. Chunky high-strength fully waterproof YKK Aquaguard zips sit alongside Italian stainless steel barrel cordlocks and rare Japanese rubber zip pulls.

Hardcore tech, subtly presented, with all the usual FRAHM features of toughness, utility, adjustability and beautiful detailing.

Use in all weathers as a rain and windproof shell, in high winds, snow, sustained or torrential rain, at high or low temperatures. With a single layer the ideal temperature range is 8c to 22c. As this is a breathable shell these ranges can be exceeded in high temperature/humidity rain or even snow, over heavier layers.

The fit is structured but forgiving, particularly due to it's stretchiness, and can accommodate a thick jumper or multiple layers.
