Mono Hooded Sweatshirt


This perfect deep winter piece, worn alone or with our signature MERINO + CARBON baselayer, provides great thermo-regulation on the coldest of winter runs. The merino terry loop backing gives great next to skin comfort while excellent stretch gives a full range of motion. A close-fitting ninja hood is fitted should the conditions need it. A piece worn as much as a lifestyle garment as on the road or trails, our bet is that it will be your favourite piece in no time.

A word from founder, Stuart: “This is my most used piece of kit from October through to March, either worn against the skin or in colder climates over a jersey or baselayer. The heat regulation on this piece is second to non, so even running in deep winter with freezing temperatures, I don’t feel cold but once warmed up and into my rhythm it maintains my comfort by cooling me to keep me warm rather than hot and sweaty. The ninja hood and hidden mitts in the cuff are incredibly useful that provide that extra warmth in the freezing conditions. It’s also my go to travel essential”.
