For downpour protection in fast and light activities like trail running, biking and adventure racing.

Gravitas is one of the worlds lightest breathable and fully waterproof jackets. A 3 layer jacket with simple but effective features to maximise protection and minimise fuss. Packing down into it’s own stuff sack and weighing less than your lunch, it’s ideal for chucking in your bag ‘just in case’ - safe in the knowledge if the weather breaks, Gravitas has got you covered.

Gravitas uses state of the art ultra fine 7 denier nylon yarns in the face and back, and a super thin PU membrane, to give the lightest 3 layer waterproof fabric we could find. 3L fabrics are more comfortable next to the skin, and more durably waterproof than 2 or 2.5L fabrics.
