Santa Monica Pier Yamatomichi UL All Weather Hoody Nomad. Ultralight by name, ultralight by nature, the UL All Weather Hoody is a seriously well thought out piece of outerwear from Japans Yamatomichi. The brand describe their UL All Weather gear as a new type of clothing they call All Weather Activewear which rethinks the way we use rainwear. Rather than rely on heavy waterproofs, they propose using ultra light, breathable shells that you can keep moving in. This anorak is a perfect example of what theyre talking about. Made from a revolutionary nylon nanofiber called Pertex Shield Air, not only is it unbelievably light, but its a lot more breathable than traditional rainwear, meaning that it works particularly well for those travelling at pace. That unique fabric is combined with a zipless design and ultrasonic welded seams to keep the raindrops out.
