Look forward to rainy days with our Cypress Cape pattern! It's perfect for cycling, dog-walking, and long walks in the rain. Wide semi-circular sleeves allow you to easily stretch your arms and reach in front, with pleats at centre back for extra mobility. A hood keeps you dry in wet weather.
The Cypress Cape is unlined, to keep it light and packable. Hems are bound with bias tape. The cape closes with a centre front zipper, which is covered by a windflap with velcro closures. Add optional reflective piping for extra visibility. Flap pockets give you a place to keep your keys or cards.
Make it in a waterproof or water-resistant fabric for wet-weather style!
