There was a time before ‘technical’ this and ‘technical’ that. A time when ‘fleece’ meant actual sheep fleece and wool was worn by everyone from North Sea fishermen to Everest expeditioners. There’s a reason for that: wool works.

Inspired by the North Wales climbing clothing of the 1950's and 1960's, Berwyn is a natural fibre chunky knitted jumper made from 100% pure lambswool.

Wool is nature’s great insulator with a properties like natural moisture management and temperature regulation that make it an ideal midlayer for outdoor activities. If it can keep a whole herd of Herdwicks alive on the fells through winter, it’ll certainly keep ewe cosy (sorry) during crisp early morning bouldering sessions and claggy pre-Sunday dinner walks.  

A thick, open knit traps lots of toasty insulating air in still conditions or under a shell, but is still incredibly breathable. A fitted cut with a ribbed hem and cuffs also enables easy layering and the stretch of the knit allows you to move unimpeded. 

Unlike that ripe old fleece you keep forgetting to wash, wool is naturally odour resistant. In fact, an airing-out in a stiff breeze is all you’ll need to do to look after your Berwyn most of the time.

Not forgetting that wool is 100% natural, biodegradable and renewable (sheep produce new fleece and sheep produce new sheep... usually in spring... they gambol... you know all this...) – what's not to like?
